Answer:

one

Step-by-step explanation:

y = 1/2x + 4

x + 2y = -8

x + 2(1/2 x + 4) = -8

x + x + 8 = -8

2x = -16

x = -8

y = 1/2 (-8) + 4

y = 0

solution: (-8, 0)

Answer: one

The given linear system has a single solution at the point (-8, 0) after solving the equations by substitution.

To determine how many solutions the given linear system has, we can substitute y from the first equation into the second equation:

y =  rac{1}{2}x + 4

x + 2(rac{1}{2}x + 4) = -8

x + x + 8 = -8

2x = -16

x = -8

Then, substituting x into the first equation:

y =  rac{1}{2}(-8) + 4

y = -4 + 4

y = 0

The linear system has a single solution, which is (x, y) = (-8, 0).

[tex]\large\boxed{(3+\sqrt{-16})(6\sqrt{-64})=-192+144i}[/tex]

Step-by-step explanation:

[tex]\sqrt{-1}=i\to i^2=-1\\\\(3+\sqrt{-16})(6\sqrt{-64})=(3+\sqrt{(16)(-1)})(6\sqrt{(64)(-1)})\\\\=(3+\sqrt{16}\cdot\sqrt{-1})(6\cdot\sqrt{64}\cdot\sqrt{-1})=(3+4i)\bigg((6)(8i)\bigg)\\\\=(3+4i)(48i)\qquad\text{use the distributive property}\ (b+c)a=ba+ca\\\\=(3)(48i)+(4i)(48i)=144+192i^2\\\\=144i+192(-1)=-192+144i[/tex]

The value of the given expression (3+√-16)(6√-64) is (-192+144i).

As the given two factors are complex numbers, therefore, we must know about the value of i

i = √(-1)

i² = (-1)

The solution of the product,

[tex](3+\sqrt{-16})(6\sqrt{-64})\\\\ = (3\times 6\sqrt{-64}) + (\sqrt{-16}\times 6\sqrt{-64})\\\\= (3+4i)(6\cdot 8i)\\\\= (3+4i)(48i)\\\\= 144i + 192(i)^2\\\\= 144i + 192(\sqrt{-1})^2\\\\= 144i + 192(-1)\\\\= -192+144i[/tex]

Hence, the value of the given expression (3+√-16)(6√-64) is (-192+144i).

Answer:

[tex]y=-5x-27[/tex]

Step-by-step explanation:

Since we are finding a parallel line, the slopes will be the same, so the second equation will also have a slope of -5.

Then, to find the y-intercept, we can use the point given and plug in.

[tex]y=-5x+b[/tex]

Answer:

D. 0.857

Step-by-step explanation:

The coefficient of determination, R-squared, is simply the square of the  correlation coefficient;

R-squared = r^2

R-squared = 0.926^2

R-squared = 0.857

Therefore, the coefficient of determination is 0.857.

Answer:

The correct answer option is D. 0.857

Step-by-step explanation:

We are given the correlation coefficient, of a data set to be 0.926 and we are to find the coefficient of determination to three decimal places.

To find that, we will use the following formula:

Coefficient of determination = [tex] r ^ 2 [/tex]

[tex] r ^ 2 [/tex] = [tex] ( 0 . 9 2 6 ) ^ 2 [/tex] = 0.857

For this case we must make a conversion. We have that by definition 1 liter equals 0.264172 gallons.

So, making a rule of three we have to:

1L ----------------> 0.264172 gallons

15L --------------> x

Where:

x: Represents gallons equivalent to 15 liters.

[tex]x = \frac {15 * 0.264172} {1}\\x = 3.96258[/tex]

Rounding out we have that 15 liters equals 3.96 gallons.

Answer:

3.96 gallons

15 liters is approximately 3.96 gallons.

Given that we need to calculate 15L is approximately how many gallons rounded two decimal places for final answer.

To convert liters (L) to gallons (gal), you need to know the conversion factor between the two units.

The conversion factor between liters and gallons is 1 L = 0.264172 gal.

Now, let's calculate how many gallons are approximately equal to 15 liters:

15 L x 0.264172 gal/L = 3.96258 gal

Rounding to two decimal places, the approximate value is 3.96 gallons.

Therefore, 15 liters is approximately 3.96 gallons.

Answer:

B

Step-by-step explanation:

B is incorrect.  Some systems have infinitely many solutions.

Answer:

The answer is Both a(x) and b(x) have the same output value at x = 2.

Step-by-step explanation:

The answer is Both a(x) and b(x) have the same output value at x = 2. Because when a(x)=b(x) the lines intersect at that point lines intersect they have a point in common. Also, a(x)=b(x) means that the outcomes are the same

The statement that is true about a(x) = b(x) at x = 2 is

Both a(x) and b(x) have the same output value at x = 2.

Option B is the correct answer.

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

a(x) and b(x)

At x = 2,

a(x) is equal to b(x)

a(x) = b(x)

This means that,

a(x) and b(x) have the same output value at x = 2.

Both a(x) and (x) have a maximum or minimum value at x = 2.

This is not true because we have to differentiate the function and put it as zero to get the maximum and minimum value at x=2.

Both a(x) and b(x) crosses the x-axis at 2.

This is not true because the function on the graph is at a point of intersection between x = 2 and the y value.

Both a(x) and (x) crosses the y-axis at 2.​

This is not true because the function on the graph is at a point of intersection between x = 2 and the y value.

Thus,

The statement that is true about a(x) = b(x) at x = 2 is

Both a(x) and b(x) have the same output value at x = 2.

Option B is the correct answer.

Answer:

Step-by-step explanation:

To solve this problem we need to solve a system of equations. We have two machines:

The machine "Paint Pro" is used for two hours.

The machine "Goldilocks" is used for an hour and a half.

When they are working at the same time, they can paint 55 square feet per minute. Together they painted 5850 square feet of wall.

Therefore, we have the following system of equations:

P + G = 55 ft^2/m

120P + 90G = 5850 ft^2 → 4P + 3G = 195

Solving the system of equations we have that:

P = 25

G = 30

Therefore, the paint pro paints 30sqft per minute and Goldilocks paints 25 sqft per minute.

Answer: [tex](-\infty,-5]\ U\ [3,\infty)[/tex]

Step-by-step explanation:

Given the inequality [tex](x-3)(x+5)\geq 0[/tex], to find the solutions, we need to follow this procedure:

- First case:

[tex]x-3\geq 0[/tex] and  [tex]x+5\geq 0[/tex]

Solve for the variable "x":

[tex]x\geq 0+3\\x\geq 3[/tex]

 [tex]x\geq 0-5\\x\geq -5[/tex]

Then:

[tex]x\geq 3[/tex]

- Second case:

[tex]x+5\leq 0[/tex] and [tex]x-3\leq 0[/tex]

Solve for the variable "x":

[tex]x\leq 0-5\\x\leq -5[/tex]

[tex]x\leq 0+3\\x\leq 3[/tex]

Then:

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

A.) There are many different expressions that can be equivalent to 4/2 and -2/3, but you just need one expression. 4/2 is equivalent to 2/1 and -2/3 is equivalent to -4/6.

Reason:

There are two ways you can find a fraction equivalent to another.

1.) First one is by reducing the fraction if possible.

Example: 5/10=1/2, 10/30=1/3, 9/16=3/4.

2.) The second one is by multiplying the numerator and the denominator by the same number, usually by 2 or 3.

Example: 1/2 x 2/2 = 2/4, so 1/2= 2/4. Another: 1/3 x 3/3 = 3/9, so 1/3=3/9

That said, 4/2 = 2/1 because it was reduced. While -2/3 = -4/6 because it was multiplied by 2/2.

Hope this Helps!

4/2 is equivalent to 1/2 when reduced by 2.

-2/3 is equivalent to -4/6 when multiplied by 2/2.

Answer:

The values of y are -33 , -15 , -5 , -5 ⇒ answer C

Step-by-step explanation:

* We will use the substitution method to solve the problem

- The quadratic equation is y = -x² + x - 3

- The values of x are -5 , -3 , -1 , 2

- We will substitute the values of x in the equation to find the

  values of y

# At x = -5

∵ y = -x² + x - 3

∵ x = -5

∴ y = -(-5)² + (-5) - 3 = - 25 - 5 - 3 = -33

∴ y = -33

# At x = -3

∵ y = -x² + x - 3

∵ x = -3

∴ y = -(-3)² + (-3) - 3 = - 9 - 3 - 3 = -15

∴ y = -15

# At x = -1

∵ y = -x² + x - 3

∵ x = -1

∴ y = -(-1)² + (-1) - 3 = - 1 - 1 - 3 = -5

∴ y = -5

# At x = 2

∵ y = -x² + x - 3

∵ x = 2

∴ y = -(2)² + (2) - 3 = - 4 + 2 - 3 = -5

∴ y = -5

* The values of y are -33 , -15 , -5 , -5 ⇒ from left to right
