They are all regular polygons
Answer:
1 pair of boots and 6 sweaters
Step-by-step explanation:
70+20s = 135
-70 -70
20s = 135
divide 20 both sides
s = 6.75
She can buy 6 sweaters because she cannot buy half a sweater.
s - sweaters
I need brainliest please
Set -x+7 = 3x+10
4x = -3
x = -3/4
y = 7.75
It depends completely on the specific scatter plot. Do you have an image? If the scattering is moving upwards as you go right on the x-axis it is a positive correlation.
