Use rounding or compatible numbers to estimate the sum 271 + 425
zysi [14]

Answer:

700

Step-by-step explanation:

For this one I'll do estimates. 271 estimated would drop down to 270. And 425 would bump up to 430. Adding 270 and 400 you would get a round number of 700!

Hope this helped.

Write an equation for this
Cerrena [4.2K]

Answer:

Y=(-x/2)-3

Step-by-step explanation:

You have two points:

(0,-3) and (-4,-1)

The formula of line trough two points is:

(Y-y1)/(y2-y1)=(x-x1)/(x2-x1)

So put these two point like (x1,y1) and (x2,y2) you will get

(Y+3)/(-1+3)=(x-0)/(-4-0)

Y+3=2x/(-4)

Y=-x/2-3
