Mia currently has 10 email subscribers to her blog and gains an average of 10 new subscribers per day. Julie currently has 100 e

user100 [1]

Answer:

Equations:

Mia: 10 + 10x = y

Julie: 100 - 5x = y

Solved: (6, 70)

Step-by-step explanation:

Mia: 10 + 10x = y

She already has 10 (10) and gains 10 (+10) per day (x). Total is y gained.

Julie: 100 - 5x = y

She already has 100 (100) and loses 5 (-5) per day (x). Total is y gained.

Then I simply solve

10 + 10x = y

100 - 5x = y

Resulting in (6, 70)

Given the function, check all transformations that occurred from the graph of the function y=x^2

Hatshy [7]

Answer: left 7 units, up 4 units, and vertical compression

Step-by-step explanation:

Given

The function is $y=x^2$

First shift it to the left by 7 units, so the function becomes

$y=(x+7)^2$

Now compress it to make it one-third

$y=\dfrac{1}{3}(x+7)^2$

Now, sift the graph upward by 4 units

$y=\dfrac{1}{3}(x+7)^2+4$

Thus , the conditions are left 7 units, up 4 units, and vertical compression.

Equation- s=db-6, solve for d

Liono4ka [1.6K]

Answer:

$d \: = \frac{s + 6}{b}$

Step-by-step explanation:

$s = db - 6$

Isolate d

$s + 6 = db$

Divide both sides of the equation by b

$\frac{s + 6}{b} = \frac{db}{b}$

Simplify

$\frac{s + 6}{b} = d \\ d = \frac{s + 6}{b}$
