Solve your equation step-by-step.
2700=2200(1+r)^5
Flip the equation.
2200(r+1)^5 = 2700
Divide both sides by 2200.
2200(r+1)^5 / 2200 = 2700 / 2200
(r+1)^5=27/22
Solve Exponent.
(r+1)^5=27/22
((r+1)5) ^1/5 = (27/22)^1/5 (Raise both sides to power)
r+1=1.041809
r+1−1=1.041809−1(Subtract 1 from both sides)
r = 0.041809
Check answers. (Plug them in to make sure they work.)
r = 0.041809 (Works in original equation)
Solve the equation for x by finding a, b, and c of the quadratic then applying the quadratic formula.
x = 7,3
So use cancelation
multiply first equation by 2
2x+8y=10
times 2
4x+16y=20
now add
4x+16y=20
<u>-4x-9y=-13 +
</u>0x+7y=7
7y=7
divide by 7
y=1
subsittue
2x+8y=10
2x+8(1)=10
2x+8=10
subtract 8 from both sides
2x=2
divide by 2
x=1
x=1
y=1

Answer:
y = 4x
Step-by-step explanation:
If you substitute the numbers for x and y, you'll find that y = 4x is the only equation that works.
