7. $(f(4 + h) - f(4))/(h) = 8$
   $h((f(4 + h) - f(4))/(h)) = h(8) \nf(4 + h) - f(4) = 8h$
   $(h + 4)^(2) + (4)^(2) = 8h \n(h + 4)(h + 4) + 16 = 8h \nh(h + 4) + 4(h + 4) + 16 = 8h$
   $h(h) + h(4) + 4(h) + 4(4) + 16 = 8h \nh^(2) + 4h + 4h + 16 + 16 = 8h$
   $h^(2) + 8h + 32 = 8h \nh^(2) + 32 = 0$
   $h = \frac{-(0) \± \sqrt{(0)^(2) - 4(1)(32)}}{2(1)}$
   $h = \frac{0 \± \sqrt{(0)^(2) - 4(1)(32)}}{2}$
   $h = (0 \± √(-128))/(2)$
   $h = (0 \± 8i√(2))/(2)$
   $h =(8i√(2))/(2)$
   $h = 4i√(2)$

8. $f(x) = (x^(2) + 4x - 32)/(x - 4) \nf(x) = (x^(2) + 8x - 4x - 32)/(x - 4) \nf(x) = (x(x) + x(8) - 4(x) - 4(8))/(x - 4) \nf(x) = (x(x + 8) - 4(x + 8))/(x - 4) \nf(x) = ((x - 4)(x + 8))/(x - 4) \nf(x) = x + 8$

$g(x) = x(2x - 5) - 2(x^(2) - 3x - 4) \ng(x) = x(2x) - x(5) - 2(x^(2)) + 2(3x) + 2(4) \ng(x) = 2x^(2) - 5x - 2x^(2) + 6x + 8 \ng(x) = 2x^(2) - 2x^(2) - 5x + 6x + 8 \ng(x) = x + 8$

The dashed figure is a dilation of the solid figure. Which of the following statements is true?a.The dilation is an enlargement.
b.The dilation is a reduction.
c.The dilation has a scale factor of 1/3.
d.The dilation has a scale factor of 3.
e.The dilation has a scale factor of 9.

Answers

The dilation is an enlargement and the dilation has a scale factor of 3. Therefore, options A and D are the correct answer.

From figure given below, square C has side of length 3 units.

What is a dilation?

Dilation is the process of resizing or transforming an object. It is a transformation that makes the objects smaller or larger with the help of the given scale factor. The new figure obtained after dilation is called the image and the original image is called the pre-image.

From given figure we can see the dashed figure, square has side of length 9 units.

Here we understood that the image has enlargement.

Now, scale factor = Dimensions of new image ÷ Dimensions of original image

= 9/3

= 3 units

Therefore, options A and D are the correct answer.

Mrs. Ramiriz is making pies to sell at the local farmer’s market. It costs her $5 to make each pie, plus a one-time cost of $30 for baking supplies. She plans to sell the pies for $12 each. Which equation can be used to find the number of pies she needs to sell to break even?a.5x – 12x = 30
b.5x + 12x = 30
c.5x + 30 = 12x
d.12x + 30 = 5x

Answers

To answer the problem above, we must first define the word break even. Break even means there is no gain or loss, the difference between the capital amount and the sale amount is zero. In equation, let x be the number of pies. 5x + 30 = 12x, $5 times the number of pies plus $30 is equal to $12 times the number of pies sold. The answer is letter C.

Answer:

c.5x + 30 = 12x

Step-by-step explanation:

Given :Mrs. Ramiriz is making pies to sell at the local farmer’s market. It costs her $5 to make each pie, plus a one-time cost of $30 for baking supplies. She plans to sell the pies for $12 each.

To Find: Which equation can be used to find the number of pies she needs to sell to break even?

Solution:

Let no. of pies be x

It cost her $5 to make each pie

so, cost of making x pies = 5x

Since there is a one-time cost of $30 for baking supplies.

So, total cost for her is 5x+30

If she sells each pie for $12

Then cost of pies = 12x

Now equation can be used to find the number of pies she needs to sell to break even:

5x+30=12x
