What is the solution of the system?
1 answer:
Answer:
(-13,-4)
Step-by-step explanation:
4x-8y=-20
9x+113=y
Substitute in y for 9x+113
4x-8y=-20
Substitute
4x-8(9x+113)=-20
Simplify
4x-72x-904=-20
Simplify
-68x-904=-20
Additive Prop. of Equality
-68x-904+904=-20+904
Simplify
-68x=884
Isolate the variable(x)
<u>-68x</u>=<u>884</u>
-68x -68x
Simplify
x=-13
Solve for y
9x+113=y
9(-13)+113=y
-117+113=y
-4=y
Check
4x-8y=-20
4(-13)-8(-4)=-20
-52+32=-20
-20=-20
9x+113=y
9(-13)+113=-4
-117+113=-4
-4=-4

Answer:
11/14
Step-by-step explanation:
11/4 / 3 1/2
3 1/2= 3*2+1= 6+1=7/2

Assuming 5a3 equals 5a^3, and the same for everything else, you would plug in 4 for a, so 5(4)^3 - 2(4)^2 + 4 - 45, which equals 247.
