Answer:
Option A, 19
Step-by-step explanation:
<u>Step 1: Find how many students are less than 69 inches</u>
65" + 66" + 67" + 68"
1 + 1 + 9 + 8
19
Answer: Option A, 19
Subtract 3x from both sides:
-6y = -3x + 6
divide both sides by -6 to get y by itself:
y = 1/2x - 1
function notation is rewriting y as a function:
f(x) = 1/2x -1
