3 & 4, And tell explanation<br><br> (P.S: Sorry for my sloppy handwriting)

Kazeer [188]

3) Altitude / Time = y2 - y1 / x2 - x1 = 30 - 60 / 6 - 3
m = -30 / 3
m = -10

In short, constant rate of change is y = -10x

b) Constant proportionality exists between two quantities, as the amount of changing in Altitude over fixed period of time is same (constant) for every instance.

4) Sales / Day = y2-y1 / x2-x1 = 2,000 - 1,000 / 6 - 3
m = 1000 / 3
m = 333.3

a) In short, Constant relationship is y = 333.3x

b) Constant proportionality exists between two quantities, as the amount of changing in Sales over fixed days is same (constant) for every instance.

Hope this helps!

Which expression is equivalent to 27 + 45?

PilotLPTM [1.2K]

9(3+5)

if you go through each answer choice you will notice that none of the rest are right

8(3+6) = 24 +48
8(19 +37) = 152 + 296
9(18 +36)= 162 +324
