Answer:
-4 1/4
Step-by-step explanation:
R=i/pt
R=1680/3000*8=1,680÷24,000
=0.07*100=7%
The center is (-1,-2)
the radius is 4
Answer:
63 1/4
Step-by-step explanation:
Answer:
(7,2)
Step-by-step explanation:
Multiply the first equation by -3
(x-3y=1) = -3x+9y=-3
Combine like terms with the new equation and the second equation
(-3x+9y=-3) + (3x-5y=11) = 4y=8
Divide each side by 4
4y/4=8/4
y=2
Plug in 2 for y in any equation. It doesn’t matter which one
x-3(2)=1
Distribute
x-6=1
Add 6 to both sides
x-6=1
+6 +6
x=7
