Answer:
(a) 
(b) 
Step-by-step explanation:
(a) 
can also be written as 
x 
the = ± y
Therefore :
= ±
since it was given that y < 0 , then the factor will be
(b) 
can also be written as : 
x
Therefore , one of the factor is
N-8=21 should be the answer
<span><span>Make it a solid line for y≤ or y≥, and a dashed line for y< or y>
</span><span>Shade above the line for a "greater than" (y> or y≥)
or below the line for a "less than" (y< or y≤).
So, the answer is A) </span></span><span>x + 4y ≥ −4
</span><span>x + 4y ≥ −4
4y </span>≥ -x - 4
y ≥ -x/4 - 1

Answer: x = 3</h3>
To get that answer, we replace y with 8 and then isolate x.
5x-7 = y
5x-7 = 8
5x = 8+7
5x = 15
x = 15/5
x = 3
