=5x²+5x²+3x+5x+4-1
=10x²+8x-3
Answer:
x=6 and y=2
Step-by-step explanation:
3x-2y=14 _1st equation
5x+y=32 _2nd equation
Multiplying 2nd equation by two and adding both equation
3x-2y=14
10x+2y=64
_________
13x=78
x=78÷13
x=6
Putting the value of x in 1st equation
3×6-2y=14
18-2y=14
2y=18-14
2y=4
y=4÷2
y=2
Answer:
the Answer is

Answer:
1.07^(-2)
Step-by-step explanation:
First, figure out what 10 to the fourth power is. This will give us 10,000.
Now, divide 107 by 10,000. That gives us 0.0107. Now put this in exponential.
In expoential, we get 1.07^(-2)
