[tex]\large\boxed{y=2\pm\sqrt{28+4x}}[/tex]

Step-by-step explanation:

[tex]2(x-2)^2=8(7+y)\\\\\text{exchange x to y, and vice versa:}\\\\2(y-2)^2=8(7+x)\\\\\text{solve for y:}\\\\2(y-2)^2=(8)(7)+(8)(x)\\\\2(y-2)^2=56+8x\qquad\text{divide both sides by 2}\\\\(y-2)^2=28+4x\iff y-2=\pm\sqrt{28+4x}\qquad\text{add 2 to both sides}\\\\y=2\pm\sqrt{28+4x}[/tex]

Answer:

y is inverse:  2 ±[tex]\sqrt{28+ 4x}[/tex] .

Step-by-step explanation:

Given: 2(x - 2)²=8(7+y)​.

To find: Find inverse.

Solution : We have given

2(x - 2)²=8(7+y)​.

Step 1: inter change the x and y.

2(y - 2)²=8(7+x)​.

Step 2:

Solve for y

On dividing both sides by 2

(y - 2)² = 4 (7+x)​.

Distributes 4 over ( 7 + x)

(y - 2)² =  28 + 4x

Taking square root both sides.

[tex]\sqrt{(y-2)^{2} } = ±\sqrt{28+ 4x}[/tex].

y - 2 =  ±[tex]\sqrt{28+ 4x}[/tex].

On adding both sides by 2

y =  + 2 ±[tex]\sqrt{28+ 4x}[/tex] .

Therefore, y is inverse : 2 ± [tex]\sqrt{28+ 4x}[/tex].

Answer:

Step-by-step explanation:

y=40×(-2)^(n-1)​

The 5th terms means n=5

y = 40 * (-2) ^ (5-1)

  = 40 * (-2) ^4

  = 40 * (16)

  = 640

Answer:

the answer should be 1

Step-by-step explanation:

4[(-3+z)2-2(-3+z)]+1

4(-6+2z+6-2z)+1

-24+8z+24-8z+1

the 24's and 8's cancel out leaving 1

To find g(h(-3+z)), we first find h(-3+z) by substituting -3+z into h(a), it becomes z^2-8z+15. Then, substitute this into g(a) to get g(h(-3+z)), which results in 4z^2-32z+61.

In the field of Mathematics, to solve the problem g(h(-3+z)), we need to substitute h into g. It means that every 'a' in g(a) will be replaced by what h(-3+z) is equal to. To find h(-3+z), we substitute -3+z into h(a) in place of a. Therefore, h(-3+z) equals to (-3+z)^2-2(-3+z). After simplifying, it becomes z^2-6z+9+6-2z=z^2-8z+15. Next, we substitute this into g(a) to get g(h(-3+z))=4[z^2-8z+15]+1=4z^2-32z+61. Hence, the solution to the problem g(h(-3+z)) is 4z^2-32z+61.

Answer:

reciprocals

Step-by-step explanation:

Let's actually find the slopes.  Then we can better compare them.

8x - 9y = 5 → - 9y = 5 - 8x → slope is m = (-8) / (-9), or 8/9.

9x - 8y = 1  →  - 8y = 1 - 9x  → slope is (-9) / (-8), or 9/8

These two slopes are reciprocals (but not negative reciprocals).

Answer:

reciprocals, but not negative reciprocals

Step-by-step explanation:

8x - 9y = 5

9y = 8x - 5

y = 8/9x - 5/9

m1 = 8/9

9x - 8y = 1

8y = 9x - 1

y = 9/8x - 1/8

m2 = 9/8

Given - Length of the Rectangular Plot : 16 meters

Answer : One side of the Square Garden plot is 8 meter

Answer:

Side of the square plot = 8 m

Step-by-step explanation:

l = 16 m

b = 4 m

Area of the rectangular plot = l * b

                                                 = 16 * 4 = 64 m²

Area of square plot = Area of rectangular plot

          side  *  side    = 64 m²

Answer:

Option C is correct.

Step-by-step explanation:

Slope of line JK

J (1,-6) K (0,4)

slope of JK = y₂ - y₁ / x₂ - x₁

Slope of JK = 4-1/0-(-6) = 3/6 = 1/2

so slope of JK = 1/2

Slope of line LM

L (-5,-3) and M(0,3)

slope of LM = y₂ - y₁ / x₂ - x₁

slope of LM = 3-(-5)/0-(-3) = 3+5/3 = 8/3

Slope of line NO

N(-6,-5) and 0 (0,0)

slope of NO = y₂ - y₁ / x₂ - x₁

slope of NO = 0-(-6)/0-(-5) = 6/5

So, slope of line NO = 6/5

Slope of PQ

P(-5,4) Q(0,-2)

slope of PQ = y₂ - y₁ / x₂ - x₁

slope of PQ = -2-4/0-(-5) = -2/5

so slope of line PQ = -2/5

the two lines are perpendicular if slope of one line is m then slope of other line is -1/m

The slope of given line =m= -5/6

The slope of line perpendicular to the given line = -1/m = 6/5

So, line NO is perpendicular to the given line as its slope is 6/5

3. The Books

The numbers of the problem make it quite easy.

We can easily figure out how many books will be stacked in each dimension of the trunk.

Length:

Books: 10 inches

Trunk: 40 iinches.

How may books can you fit lengthwise in the trunk?  40 / 10 = 4

We then to the same for the width:

Books: 6 inches

Trunk: 24 inches

How many books can you stack wide-wise in the trunk?  26/4 = 4

And then the height:

Books: 2.5 inches

Trunk: 20 inches

How many books stacked in height? 20 / 2.5 = 8

So, we can saw the trunk is 4 books long, by 4 books wide by 8 books thick... so, the number of books you can fit in that trunk is:

B = 4 * 4 * 8 = 128

4. Tomato juice

First, we have to find the volume of that big can...

The vertex is: [tex](\frac{3}{2},\ \frac{7}{2})[/tex]

The axis of symmetry is:

[tex]x=\frac{3}{2}[/tex]

Step-by-step explanation:

For a quadratic equation of the form:

[tex]y=ax^2 + bx +c[/tex]

The vertex of the parabola will be the point: [tex](-\frac{b}{2a},\ f(-\frac{b}{2a}))[/tex]

In this case we have the following equation:

[tex]y= -2x^2+6x-1[/tex]

Note that:

[tex]a=-2\\b=6\\c=-1[/tex]

Then the x coordinate of the vertex is:

[tex]x=-\frac{b}{2a}[/tex]

[tex]x=-\frac{6}{2(-2)}[/tex]

[tex]x=\frac{3}{2}[/tex]

Then the y coordinate of the vertex is:

[tex]y= -2(\frac{3}{2})^2+6(\frac{3}{2})-1[/tex]

[tex]y=\frac{7}{2}[/tex]

The vertex is: [tex](\frac{3}{2},\ \frac{7}{2})[/tex]

For a quadratic function the axis of symmetry is always a vertical line that passes through the vertex of the function.

Then the axis of symmetry is:

The answer is [tex]\( 24xy^2 \)[/tex].

To solve the expression [tex]\( 3x \cdot 8y^4 \)[/tex], we first multiply the coefficients and the variables separately. The coefficients are 3 and 8, and when multiplied, they give us 24. For the variables, we multiply x by [tex]\( y^4 \)[/tex], keeping in mind that when multiplying exponents with the same base, we add the exponents. Therefore, [tex]\( x \cdot y^4 \)[/tex] remains [tex]\( xy^4 \)[/tex].

Combining the coefficient and the variables, we get \( 24xy^4 \). However, we can simplify this further by recognizing that any variable raised to the power of 1 is simply the variable itself. Thus, [tex]\( xy^4 \)[/tex] is equivalent to [tex]\( xy^2 \)[/tex] because [tex]\( y^1 \)[/tex] is just [tex]\( y \)[/tex].

So the final simplified expression is [tex]\( 24xy^2 \)[/tex].

Step-by-step explanation:

In this problem we have the following expression

[tex]a + b^2[/tex]

Note that it depends on two variables a and b

Evaluating the expression for a = 2 and b = 3 means that you must replace the variable "a" with the number 2, and you must replace the variable "b" with the number 3

So we have that:

[tex]a + b^2 = 2 + 3^2[/tex]

[tex]a + b^2 = 2 +9[/tex]

[tex]a + b^2 = 11[/tex]

Answer:

your answer would be just x

Step-by-step explanation:

you just subtract the exponents

The expression x^-8/x^-7 simplifies to 1/x. This is due to the rule for dividing exponential expressions with the same base, which involves subtracting the exponents.

To solve x^-8/x^-7, we need to understand the rule for division of expressions with exponents which is: x^a / x^b  = x^(a-b).

When you divide exponential expressions with the same base, you subtract the exponents.

In our case, x^-8 / x^-7 = x^(-8 - -7). This simplifies to x^-1 or x^-1 = 1/x. So, the result is 1/x.

Answer:

1. Number line 2

2. Number line 1

3. Number line 4

4. Number line 3

Step-by-step explanation:

1. x – 99 ≤ -104

Solving by adding +99 on both sides

x - 99 +99 ≤ -104 +99

x ≤ -5

Number line 2 represent x ≤ -5

2. x – 51 ≤ -43

Adding +51 on both sides

x -51 +51  ≤ -43 +51

x ≤ 8

Number line 1 represent x ≤ 8

3. 150 + x ≤ 144

Adding -150 on both sides

150 + x -150 ≤ 144 -150

x ≤ -6

Number line 4 represent x ≤ -6

4. 75 < 69 – x

Adding +x on both sides

75 + x < 69 -x +x

x < 69 -75

x < -6

Number line 3 represent x < -6

The correct matches are:

[tex]\(x - 99 \leq -104\)[/tex] with the number line showing [tex]\(x \leq -5\)[/tex].

[tex]\(x - 51 \leq -43\)[/tex] with the number line showing [tex]\(x \leq 8\)[/tex].

[tex]\(150 + x \leq 14475\)[/tex] with the number line showing [tex]\(x \leq 14325\)[/tex].

[tex]\(69 - x < 14475\)[/tex]  with the number line showing [tex]\(x > -14406\)[/tex].

To solve the given inequalities and match them to their corresponding number lines, we will first solve each inequality algebraically and then represent the solution on a number line.

1. For the inequality [tex]\(x - 99 \leq -104\)[/tex], we add 99 to both sides to isolate \[tex](x\)[/tex]:

[tex]\[x \leq -104 + 99\][/tex]

[tex]\[x \leq -5\][/tex]

This means that all values of [tex]\(x\)[/tex] less than or equal to -5 satisfy the inequality.

2. For the inequality[tex]\(x - 51 \leq -43\)[/tex], we add 51 to both sides:

[tex]\[x \leq -43 + 51\][/tex]

[tex]\[x \leq 8\][/tex]

This means that all values of [tex]\(x\)[/tex] less than or equal to 8 satisfy the inequality.

3. For the inequality [tex]\(150 + x \leq 14475\)[/tex], we subtract 150 from both sides:

[tex]\[x \leq 14475 - 150\][/tex]

[tex]\[x \leq 14325\][/tex]

This means that all values of [tex]\(x\)[/tex] less than or equal to 14325 satisfy the inequality.

4. For the inequality [tex]\(69 - x < 14475\)[/tex], we subtract 69 from both sides and reverse the inequality sign because we are dividing by a negative number (-1):

[tex]\[-x < 14406\][/tex]

[tex]\[x > -14406\][/tex]

This means that all values of [tex]\(x\)[/tex] greater than -14406 satisfy the inequality.

Now, let's represent these solutions on number lines:

- For [tex]\(x \leq -5\)[/tex], the number line will have a closed circle at -5 and shading to the left of -5.

- For [tex]\(x \leq 8\)[/tex], the number line will have a closed circle at 8 and shading to the left of 8.

- For[tex]\(x \leq 14325\)[/tex], the number line will have a closed circle at 14325 and shading to the left of 14325.

- For [tex]\(x > -14406\)[/tex], the number line will have an open circle at -14406 and shading to the right of -14406.

Matching the inequalities to the number lines:

- The inequality [tex]\(x - 99 \leq -104\)[/tex] corresponds to the number line with a closed circle at -5 and shading to the left.

- The inequality [tex]\(x - 51 \leq -43\)[/tex] corresponds to the number line with a closed circle at 8 and shading to the left.

- The inequality [tex]\(150 + x \leq 14475\)[/tex] corresponds to the number line with a closed circle at 14325 and shading to the left.

- The inequality [tex]\(69 - x < 14475\)[/tex] corresponds to the number line with an open circle at -14406 and shading to the right.

Therefore, the correct matches are:

[tex]\(x - 99 \leq -104\)[/tex] with the number line showing [tex]\(x \leq -5\)[/tex].

[tex]\(x - 51 \leq -43\)[/tex] with the number line showing [tex]\(x \leq 8\)[/tex].

[tex]\(150 + x \leq 14475\)[/tex] with the number line showing [tex]\(x \leq 14325\)[/tex].

[tex]\(69 - x < 14475\)[/tex]  with the number line showing [tex]\(x > -14406\)[/tex].

Answer:

The coordinates of the point in question is (1, 3).

Step-by-step explanation:

Point (-1, 7) is above and to the left of the point (4, -3). The point in question is to the right and below the point (-1, 7).

What will be the horizontal distance between the point (-1, 7) and the point in question?

The horizontal distance between the point (-1, 7) and (4, -3) is 5. Let the horizontal distance between the point (-1, 7) and the point in question be [tex]a[/tex]. Let the horizontal distance between the point in question and point (4, -3) be [tex]b[/tex].  

[tex]\displaystyle \frac{a}{b} = \frac{2}{3}[/tex].

[tex]\displaystyle a = \frac{2}{3} \; b[/tex].

[tex]\displaystyle b = \frac{3}{2}\; a[/tex].

However,

[tex]a + b = 5[/tex].

[tex]\displaystyle a + \frac{3}{2}\; a = 5[/tex].

[tex]\displaystyle \frac{5}{2}\; x= 5[/tex].

[tex]a = 2[/tex].

In other words, the point in question is 2 units to the right of the point (-1, 7). The x-coordinate of this point shall be [tex]-1 + 2 = 1[/tex].

The vertical distance between the point (-1, 7) and the point (4, -3) is 10. Similarly, the point in question is [tex](2/5) \times 10 = 4[/tex] units below the point (-1, 7). The y-coordinate of this point will be [tex]7 - 4 = 3[/tex].

Thus, the point in question is (1, 3).

The correct Answer is D[tex]\sqrt{13} - \sqrt{11}[/tex]

Step-by-step explanation:

[tex]x(x-3)=x\\x^2-3x-x=0\\x^2-4x=0\\x(x-4)=0\\x=0\vee x=4[/tex]

[tex]\text{Hey there!}[/tex]

[tex]\text{In order for you can do the distributive property then work from there}[/tex]

[tex]\text{x(x - 4) = x}\\\\\text{x(x)=x}^2\\\\\text{x(-3)= -3x}[/tex]

[tex]\text{Subtract by the value of x on your sides!}[/tex]

[tex]\text{Your new equation becomes: x}^2\text{- 3x = x}[/tex]

[tex]\text{Like}\downarrow[/tex]

[tex]\text{x}^2\text{- 3x - x = x - x}[/tex]

[tex]\text{x - x = 0 }[/tex]

[tex]\text{-3x + (-1x) = -4x}[/tex]

[tex]\text{Our equation becomes: x}^2\text{- 4x = 0}[/tex]

[tex]\text{Next, we have to FACTOR on the LEFT side of your equation}[/tex]

[tex]\text{x(x - 4) = 0}[/tex]

[tex]\text{Set the numbers to FACTOR out to 0}[/tex]

[tex]\text{Like: x = 0 or x - 4 = 0}\text{ (solve that and you SHOULD have the x-values)}[/tex]

[tex]\boxed{\boxed{\bf{Answer: x = 0\ or \ x =4}}}\checkmark[/tex]

[tex]\text{Good luck on your assignment and enjoy your day!}[/tex]

Answer:h= [tex]\frac{(p/0.7-b)}{r}[/tex]

Step-by-step explanation:

1) p/0.7=rh+b

2) (p/0.7)-b=rh

3) [tex]\frac{(p/0.7-b)}{r}[/tex] =h

h= [tex]\frac{(p/0.7-b)}{r}[/tex]

The equivalent equation for isolated variable h = [tex]\frac{p-0.7b}{r}[/tex] obtained from the equation p = 0.7(rh + b).

Isolating a variable is the re-arrangement of the equation for the required variable. Even though rewriting the terms, doesn't affect the logic of the equation. It forms an equivalent equation.

The given equation is p = 0.7(rh + b)

Where,

p - home pay

h - working hours

r - the rate of dollars per hour

b - bonus received

Re-writing the equation for the variable h:

p = 0.7(rh + b)

⇒ p/0.7 = rh + b

⇒ p/0.7 - b = rh

⇒ h = p/0.7r -b/r

∴ h = [tex]\frac{p-0.7b}{r}[/tex]

Therefore, variable h is isolated and obtained an equivalent equation.
