The answer is -10.
20/-2=-10
You would earn 60 for 6 hours of work.
We have to compute: Δ y / Δ x.
The interval is [ 2, 5 ] and y = 4 x - 9.
y 1 = 4 · 2 - 9 = 8 - 9 = - 1
y 2 = 4 · 5 - 9 = 20 - 9 = 11
Δ y / Δ x = ( y 2 - y 1 ) / ( x 2 - x 1 ) =
= ( 11 - ( - 1 ) ) / ( 5 - 2 ) = ( 11 + 1 ) / 3 = 12 / 3 = 4
Answer:
Δ y / Δ x = 4
Answer:
Step-by-step explanation:
x- axis is 2 units away
Answer: 3
Step-by-step explanation:
Let say x the width of the tank,
x+4 its length,
x+2 its height

<u>width=3</u>
length=3+4=7
height=3+2=5
