The answer to your question is 5.100
Answer:
b
Step-by-step explanation:
You can plug -x - 1 for y in the first equation
2x - (-x - 1) = 10
2x + x + 1 = 10
Combine
3x = 9
Divide
x = 3
Plug 3 for x in any equation ( I'll use th second equation )
y = - (3) - 1
y = - 3 - 1 = -4
x = 3 ; y = -4
(3, -4)
A=78.54
A=1
/4πd2=1
/4·π·10^2≈78.53982m²
Hope this helps

A=πr2
d=2r
Answer:
m=40
Step-by-step explanation:
First you would subtract 50 from both sides to get -> m/40=1. So finally if you want to multiply 40 to both sides it would be m=40. Hope this helps!
