Answer:
y = 30
Step-by-step explanation:
We can use ratio's to solve this
40 20
----- = -----------
100 20 + y
Using cross products
40 * (20+y) = 20*100
Distribute
800 + 40y = 2000
Subtract 800 from each side
40y = 2000-800
40y = 1200
Divide by 40
y = 1200/40
y =30
C; this is because the line of beat fit isn’t linear but curved in that one graph.
Answer:
B
Step-by-step explanation:
Subtract 20 from both sides:

Divide both sides by -1:

Square both sides:

Subtract 9 by both sides:

Divide both sides by -8:

That means that either a or b is correct and since 9/8 is positive that means it needs to bee less than 9/8 so the correct answer is B
