(7x +6) - (5x - 4) = 180
BartSMP [9]

Answer:

x= 85

Step-by-step explanation:

(7x+6)-(5x-4)=180

There is a negative 1 between the two parenthesis

-1(5x-4)

-5x+4

Now plug it back into the equation and take out the parenthesis

7x+6-5x+4= 180

2x+10=180    Now we can solve

    -10  -10

2x= 170

2x/2 = 170/2

x= 85

I hope this helps! :)

PLEASE HELP
SVETLANKA909090 [29]

Answer:

f(x) = 2(x + 4)² - 2

Step-by-step explanation:

Equation of quadratic function whose vertex is (h, k),

f(x) = a(x - h)² + k

Equation of the function with vertex (-4, -2) shown in the graph will be,

f(x) = a(x + 4)² - 2

This graph is passing through a point (-6, 6) also,

6 = a(-6 + 4)² - 2

6 + 2 = a(-2)²

a = \frac{8}{4} = 2

Therefore, quadratic function is f(x) = 2(x + 4)² - 2
