Given: " If h(x) = -3x <span>−</span><span> 10, find h(-3). "
So; we plug in "-3" for all values of "x" ; to solve for " h(-3)" ; as follows:
</span>→ h(-3) = -3(-3) − 10 = 9 − 10 = - 1 .
The answer is: " - 1 " .

Vertical line is when x=0
so the vertical line passing through (7,-5) would be y=-5
Horizontal line is when y=0
So the horizontal line passing through (7,-5) would be x=7
Answer:

Answer:
B
Step-by-step explanation:
Jamal's score is 80
<u>Explanation:</u>
Given:
Number of questions = 100
Let w be the number of wrong answers
Let r be the number of right answers
According to question,
r = 4w
r + w = 100
Solving both the equations we get:
4w + w = 100
5w = 100
w = 20
If w = 20 then r = 4 X 20 = 80
Therefore, Jamal's score is 80
