Use the definition of absolute value.
• If 4x + 3 ≥ 0, then
|4x + 3| = 15
4x + 3 = 15
4x = 12
x = 3
• Otherwise, if 4x + 3 < 0, then
|4x + 3| = 15
-(4x + 3) = 15
4x + 3 = -15
4x = -18
x = -9/2
Then the solutions are {-9/2, 3}.
Y=3x+4
it’s hard to tell where the line is meeting the corners of the small squares but slope intercept is y=mx+b
m is slope
b is y intercept
it appears as the line intercepts the y axis at 4 so that is your y intercept. the slope is 3/1 which is just 3 so you would end up with y=3x+4
Answer:
its 3
so its
(4x+4)^2-2(4x+4)-5
so first you have to do
(4x+4)(4x+4)
the answer is 16x^2+32x+16
and then you do -2(4x+4) and then you add them so then its
16x^2+32x+16-8x-8-5
and then you just add like terms so its
16x^2+24x+3
and then you insert 0 for x
so the answer is 3
