The top is correct, but they made a small typo. The correct answer is f(x) = (x – 8)^2 – 56. Hope this helps!

Answer:

f(x) = x² + 8 - 16x

= x² - 16x + 8

= (x² - 16x + 64) - 64 + 8

= (x + 8)² - 56

3. x + 4y = 30<br> x - 2y = 0
kolbaska11 [484]

Answer:

Step-by-step explanation:

Given that:

x + 4y = 30

x - 2y = 0

Subtracting both equations:

6y = 30

y = 30/6

y = 5

Putting in above equation

x + 4(5) = 30

x + 20 = 30

x = 10

Graph the linear equation using the slope and​ y-intercept.<br> Y=4X+3
JulsSmile [24]

The slope-intercept form: y = mx + b

m - slope

b - y-intercept

We have y = 4x + 3

m = 4 - slope

3 - y-intercept


m=\dfrac{\Delta Y}{\Delta x}\to4=\dfrac{4}{1}
