Two functions are shown in the table below.

SVETLANKA909090 [29]

Answer:

$(d)\ x = 4$

Step-by-step explanation:

Given

$f(x) = -x^2 + 4x + 12$

$g(x) = x + 8$

Required

Find x such that: $f(x) = g(x)$

This gives:

$-x^2 + 4x + 12 = x+8$

Collect like terms

$-x^2 + 4x -x + 12 -8=0$

$-x^2 + 3x +4 =0$

Expand

$-x^2 + 4x - x+4 =0$

Factorize

$x(x - 4) - 1(x-4) = 0$

Factor out x - 1

$(x- 1)(x - 4)=0$

Solve:

$x =1\ or\ x = 4$

camela is trying to find the equation of a line that passes through the points (-1, 16) and (5, 88). does the equation y= 12

lutik1710 [3]

I'm assuming you meant does y=12x pass through those coordinates, and if that's the case, then the answer is no.

Hope that helps :)

What is the slope and y-intercept of the line y=1/3x-7

Juli2301 [7.4K]

Answer:

1/3, -7

Step-by-step explanation:

Before answering this, I will need to assume that you actually meant

y = (1/3)x - 7. Comparing this to y = mx + b, we see that the slope, m, is 1/3 and the y-intercept, b, is -7.
