The minimum happens at x=-b/2a, in this case, b=-10, a=1
so x=5

Can someone pls help me with number 5 pls show your work so i can understand thanks
Natali [406]

Step-by-step explanation:

Let's represent Aaron's age with x and

Charlene's age with x+8

x+x+8=44

2x+8=44

2x=44-8

2x=36

x=36÷2

x=18

Aaron is 18 years old.

While Charlene is 18+8=26 years old.

<em>Hope this </em><em>helps!</em>

9. Solve the equation.<br> 4(6 – x) + 4 = 2 (3x + 1) – 6
sasho [114]

Answer:

x=3.2

Step-by-step explanation:

4(6 – x) + 4 = 2 (3x + 1) – 6

24 - 4x + 4 = 6x + 2 - 6

28 - 4x = 6x -4

-4x - 6x = - 4 - 28

-10x = - 32

divide both sides

x = 16/5 or x = 3.2

hope this helps :)

The vertex form of a function is g(x) = (x – 3)2 + 9. How does the graph of g(x) compare to the graph of the function f(x) = x2?
Alekssandra [29.7K]

we have

g(x)=(x-3)^{2}+9

This is the equation of a vertical parabola with vertex at point (3,9)

The parabola open upward------> the vertex is a minimum

f(x)=x^{2}

This is the equation of a vertical parabola with vertex at point (0,0)

The parabola open upward------> the vertex is a minimum

so

the rule of the translation is

f(x)------> g(x)

(x,y)-----> (x+3,y+9)

that means

the translation is 3 units to the right and 9 units up

the graph of the function g(x) is the translated graphic of the function f(x) 3 units to the right and 9 units up

therefore

<u>the answer is</u>

g(x) is shifted 3 units right and  9  units up
