-2x + 2y=2<br><br> What’s the slope for m and y and b
stellarik [79]

Answer:

y=x+1

m=1

b=1

Step-by-step explanation:

-2x+2y=2

+2x      +2x

2y=2+2x

divide by 2

y=1+x

rewrite

y=x+1

Since b is the y intercept, b would equal 1.

The slope of the line, or m, would be 1 as well.

If a 12-sided regular polygon rotates about its center, at which angle of rotation will the image of the polygon coincide with t

A polygon can rotate a total of 360. This one has 12 sides and 12 angles that are all congruent. So to coincide with original image, it must rotate 1/12 of the way around

360/12=30

0.01v+0.09(8000-v)=650
vova2212 [387]

Answer:

v = 875

Step-by-step explanation:

0.01v + 0.09(8000-v) = 650

Multiply the parenthesis

0.01v + 720 - .09v = 650

Combine like terms

720 - 0.08v = 650

Add 0.08v to both sides

720 = 650 + 0.08v

Subtract 650 from both sides

70 = 0.08v

Divide by 0.08 on both sides

v = 875

Hope this helps :)
