Answer: a) w = -26, -2
b) x = -4, -1
c) k = 17, -1
d) z = 65, 935
Multiple choice: D)
Step-by-step explanation:
a) (w+26)(w+2) = 0
w = -26, w = -2
b) (x+4)(x+1) = 0
x = -4, x = -1
c) (k-17)(k+1) = 0
k = 17, k = -1
d) (z-65)(z-935) = 0
z = 65, x z 935
Multiple Choice
D)
Multiply all terms by 2.

<h2>
x≤5</h2>
Step-by-step explanation:
The line is vertical, so it is <em>on x</em>
the line is on <em>x=5</em>
the line is whole so it is less or greater than and equal to
the shaded part is to the left, so it is less than
So, the inequality represented by the graph is x≤5
