A semicircle has endpoints (-4, 1) and (7, 1) What is the length of the semicircle to the nearest tenth?explain A.) 17.3
B.) 4.3
C.) 34.6
D.) 9.4

9 x 8 divided by (5-3)=36

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

b. 2 and 4

step-by-step explanation:

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5
