Find the factored form of
-7y - y2 = 0

Answer:

Step-by-step explanation:

Perimeter= 2L+2W. If L=3W(three times the width) then 2(3W)+2W=112. Or 6W+2W=112 which is equal to 8W=112. To solve for the width, divide both sides by 8 and find 112/8=14, therefore W=14.

Answer:

14 cm

Step-by-step explanation:

Given the length is 3 times the width

If each width is denoted by W, then each length is L = 3W

Perimeter (add up all lengths and widths),

= L + L + W + W

= 3W + 3W + W + W

= 8W

Given that the max perimeter is 112cm

hence 8W = 112,

W = 14 cm at most

Answer:

Height of parallelogram = 5.07 inches

Step-by-step explanation:

We are given Area of Parallelogram = 32 in^2

Height of Parallelogram = ?

Base of Parallelogram = 6.3 in

The formula to find the Area of Parallelogram is:

Area of Parallelogram = Base * Height

32 = 6.3 * Height

=> Height = 32/6.3

=> Height = 5.07 inches

So, height of parallelogram = 5.07 inches

The missing variable for this parallelogram is the height, which is 5.08 inches.

We begin with the formula for the area of a parallelogram:

We plug in all given information.  We know the area, 32 in², and we know the base, 6.3 in:

Next we solve for our variable, h.  Since 6.3 and h are beside each other, we know they have been multiplied.  To cancel this, we will divide both sides by 6.3:

This means that the missing variable, the height, is approximately 5.08 inches.

Answer:

(-7,3)

Step-by-step explanation:

Given that point (-7,1) is on the graph of f(x), means that

[tex]f(-7)=1[/tex]

To find the corresponding point for the function y=3f(x), you have to find the value of the function at x=-7.

Substitute x=-7 into the function's expression:

[tex]y=3f(-7)[/tex]

Since f(-7)=1, we have that

[tex]y=3\cdot 1=3[/tex]

Hence, the corresponding point has coordinates (-7,3)

To find the corresponding point for the function 3f(x), multiply the y-coordinate of the given point by 3.

To find the corresponding point for the function 3f(x), we need to multiply the y-coordinate of the given point by 3.

Given that (-7,1) is on the graph of f(x), we multiply the y-coordinate by 3 to get (1*3) = 3.

Therefore, the corresponding point for the function 3f(x) is (-7,3).

Answer:

Simplify by combining like terms, she combined 1/2 and 1 which equals 3/2. Your answer is A.

Step-by-step explanation:

The missing step in Fiona's solution to the equation 1/2 - 1/3(6x - 3) = -13/2 was the distribution of the 1/3 to each term in the parentheses and the multiplication of the equation by 2.

To find the missing step of Fiona's solution, we first need to simplify the equation. The given equation is 1/2 - 1/3(6x - 3) = -13/2. The missing step may be the distribution of the 1/3 onto the (6x - 3). This leads to 1/2 - (2x - 1) = -13/2.

Following this, we need to remove the fraction on the left side of the equation by multiplying the entire equation by 2. This gives 1 - (4x - 2) = -13. Finally, simplifying this further gives us -4x = -16, and solving for x we get x = 4.

Therefore, Fiona's missing step was the distribution of the 1/3 to each term in the parentheses and the multiplication of the equation by 2 to get rid of fractions.

Answer:

Step-by-step explanation:

We know:

1. Diagonals of a rhombus are perpendicular.

2. Diagonals divide the rhombus on four congruent right triangles.

3. The sum of measures of acute angles in a right triangle is equal 90°.

Angles CAD and ACB are alternate angles. Therefore they are congruent:

m∠DAC = m∠ACB ⇒ m∠ACB = x°.

From 3. we have the equation:

(5x - 18) + x = 90

(5x + x) - 18 = 90              add 18 to both sides

6x = 108             divide both sides by 6

x = 18

Answer:

Option D

Step-by-step explanation:

In any Rhombus the diagonals bisect the angles. The diagonals are perpendicular bisectors of each other.

So,

5x-18+x+90=180 ( Angles of a triangle add to 180 degrees)

Simplifying like terms:

6x+72=180

Subtracting  72 both sides :

6x= 108

Dividing by 6 both sides:

x=18.

Option D is correct.

Answer:

the first one is graph c and the second, graph b.

Step-by-step explanation:

They are both linear inequalities, so for both, you have to solve for x first. For the first one, since x is basically multiplied to 2 (2x), you have to divide both sides to get x by itself, and you get x>25. The graph has to have an opened circle, and the arrow should go to the right because all the numbers greater than 25 can be x. For the second one, you have to subtract 6 to both sides to get x by itself which then leaves you with ×<26. This one should also be an opened circle, and is going to the left, because all the numbers less than 26 can be x.

Answer:

f(6)  =  68

Step-by-step explanation:

f(6)

f(n+1)=f(n)-8

n = 5, so

f(6)=f(5)-8

and with n = 4

f(5)=f(4)-8 , so

f(4) = f(3) - 8

f(3) = f(2) - 8 = 100 - 8 = 92

f(3)  = 92

Then, we can go and find the result

f(4) =[92] - 8  = 84

f(5)=[84] - 8 = 76

f(6)  = [76] -8 = 68

[tex]f(n+1)=f(n)-8\\f(2)=100\\\\f(3)=100-8=92\\f(4)=92-8=84\\f(5)=84-8=76\\f(6)=76-8=68[/tex]

Multiply 9 by 6

Step-by-step explanation:

7:9 is the ratio

We multiply the first term by 6.

What we do to one side, we do to the other

7*6=42

9*6 = 54

That way we keep the ratio in the same proportion

42:54

Answer: Multiply 9 by 6.

Step-by-step explanation:

Divide 45 by 3 ( the quantity of consecutive numbers) This will give you the middle number, then use the number higher and lower.

45/3 = 15

14 + 15 + 16 = 45

The 3 numbers are 14, 15 and 16

For this case we have that the variable "x" represents the number of hours that Leticia uses to take care of children on Saturday.

IF on Friday I use 4 hours ($ 8 each) and on Saturday "x" hours ($ 8 each) obtaining a profit of $ 72, we have the following equation:

[tex]8 (4 + x) = 72[/tex]

We apply distributive property:

[tex]32 + 8x = 72\\8x = 72-32\\8x = 40\\x = \frac {40} {8}\\x = 5[/tex]

So, on Saturday she spent 5 hours.

ANSWER

b) The degree of the function is even so the ends of the graph continue in the same direction. because the leading coefficient is negative the left side of the graph continues down the coordinate plane and the right side also continues downward

EXPLANATION

The given polynomial function is

[tex]f(x) = - {x}^{4} + 1[/tex]

The degree of this function is even which is 4.

The function extends in the same direction at both ends.

In other words both ends continue in the same direction.

Since the coefficient of the leading term is negative, the graph extends to negative infinity at both ends.

The correct answer is B

Answer:

[tex]x=15.56[/tex]

Step-by-step explanation:

We can use the law of sines here. However, we will first need to solve for the missing angle.

The interior angles of a triangle add up to 180.

Therefore,

[tex]35+90+x=180[/tex]

where [tex]x[/tex] is the missing angle.

[tex]35+90+x=180[/tex]

[tex]x+125=180[/tex]

[tex]x=55[/tex]

So the missing angle is 55 degrees.

Now we can use the law of sines to set up a proportion.

[tex]\frac{19}{sin(90)}=\frac{x}{sin(55)}[/tex]

Now simplify the equation.

[tex]x=15.56[/tex]

Rounded to the nearest hundredth.

Answer:

x ≈ 19.6

Step-by-step explanation:

Since the triangle is right use the cosine ratio to solve for x

cos35° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{x}{19}[/tex]

Multiply both sides by 19

19 × cos35° = x, hence

x ≈ 19.6 ( to 1 dec. place )

Answer:

y-intercept=15 and x-intercept = 5

Step-by-step explanation:

We have the following equation:

3x + y = 15.

To find the x-intercept and y-intercept we have to do the following:

1. To find the y-intercept we need to make x=0, and solve for 'y' as follows:

3x + y = 15 ⇒ 3(0) + y = 15 ⇒ y=15

2. To find the x-intercept we need to make y=0, and solve for 'x' as follows:

3x + y = 15 ⇒ 3x + (0) = 15 ⇒ 3x = 15  ⇒ x=5

Therefore, the y-intercept=15 and x-intercept = 5

B. [tex]y-9=2(x-1)[/tex]

Step-by-step explanation:

We have been given graph of a line on coordinate plane. We are asked to find the equation of our given line.

First of all, we will find slope of our line using points [tex](-2,3)\text{ and }(1,9)[/tex] in slope formula:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\frac{9-3}{1-(-2)}[/tex]

[tex]m=\frac{6}{1+2}[/tex]

[tex]m=\frac{6}{3}[/tex]

[tex]m=2[/tex]

We can see that our given equations are in point-slope form of equation: [tex](y-y_1)=m(x-x_1)[/tex], where,

m = Slope,

[tex](x_1,y_1)[/tex] = Coordinates of point on line.

We can get two equations of our line in point-slope form as:

[tex](y-3)=2(x--2)[/tex]

[tex](y-3)=2(x+2)[/tex] or

[tex](y-9)=2(x-1)[/tex]

Upon looking at our given choices, we can see that option B is the correct choice.
