6 0

Answer:

The parent function is x^2

Step-by-step explanation:

y = (x-2)^2 - 5

Remove the shift down

y = (x-2)^2

Remove the shift to the right

y = x^2

The parent function is x^2

Since the maximum budget that Jennifer has is $62.10. You can input P=62.10 so now you can start solving.

Steps:
62.10 = (20+0.5x)+0.15(20+0.5x)
62.10 = 20 + 0.5x + 3 + 0.075x
(Combine "like" terms: so for here you combine x together)
62.10 = 0.575x + 20 +3
62.10 = 0.575x + 23
-23 - 23
39.10 = 0.575x
(Now divide 0.575 on both sides.)
$\frac{39.10}{.575} = \frac{.575x}{.575}$
You should end up with:
x = 68

Jennifer can have 68 pages in her book to fit her budget.

Y is inversely proportional to x when y=7,x=9

Leni [432]

Answer:

Y = k/x for some fixed number constant k

7 = k/9

k = 63

so Y = 63/x

14 = 63/x

14 x = 63

x = 63/14 = 9/2

Step-by-step explanation:

not too hard ;)

The first hexagon is dilated to form the second hexagon. Select answers from the drop-down menus to correctly complete the state

shusha [124]

Answer: The scale factor is 1.3 .

Step-by-step explanation:

Given: The first hexagon is dilated to form the second hexagon.

The side length of first hexagon=5 units.

The side-length of second hexagon= 6.25 units

When a shape having measure x is dilated by using a scalar factor of k, then the side measure (y) of the image is given by:-

$y=kx$

Substitute, y=6.5 and x=5 to find the value of k we get

$6.5=5k\\\Rightarrow\ k=\frac{6.5}{5}=1.3$

Hence, the scale factor is 1.3

How to translate the verbal phrase Seven-eighths of r is added to 12 into an algebraic expression

satela [25.4K]

Answer:

'Seven-eighths of $r$ is added to 12' can be represented algebraically as:

$\frac{7}{8}r+12$

Step-by-step explanation:

Given:

Verbal phrase : 'Seven-eighths of $r$ is added to 12'

To write the verbal phrase into an algebraic expression.

Solution:

The verbal phrase 'Seven-eighths' means 7 parts out of 8 and tus can be represented as a fraction = $\frac{7}{8}$

'Seven-eighths of $r$ ' : The phrase represents the fractional part of variable $r$ .

Thus, we have : $\frac{7}{8}\times r=\frac{7}{8}r$

'Seven-eighths of $r$ is added to 12' can be represented algebraically as:

$\frac{7}{8}r+12$
