If two linear equations have one solution, then the... A- Slopes are the same but the y-intercepts are different
B- Slopes are different
C- Slopes are the same and the y-intercepts are the same

A-Slopes are different

Step-by-step explanation:

The slopes need to be different and if there is only one solution then the y-intercepts we wouldn’t need to worry about that because if the slopes are different then it will intercsect

no not all of them.

step-by-step explanation:

some of them have a square base.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
