The system of equations to find the value of x, the first number, and y, the second number are;
<em>y = -x + 84</em>
<em>y = x² + 6</em>
<h3>System of equation</h3>
The system of equation are equations that contains more than two equation and unknown.
Let the two unknown numbers x and y
If the sum of two numbers is 84, hence;
x +y = 84
y = -x + 84
If the square of the first number is 6 more than the second number, hence;
x² = y + 6
Substitute equation 2 into 2 to have:
x² = y + 6
x² = (-x+84) + 6
x² = -x+84 + 6
x² +x+84 + 6 = 0
x² +x + 90 = 0
Hence the system of equations to find the value of x, the first number, and y, the second number are;
<em>y = -x + 84</em>
<em>y = x² + 6</em>

Answer:
Domain of inverse: 
Range of inverse: 
Explanation:
The domain and range swap. This is because the inputs (x) and outputs (y) swap roles when going from the original function to the inverse, and vice versa.
I'm pretty sure that a rate is a ratio and a ratio is a rate because 2:3 can be saying a rate and it can be a ratio as well. I don't know how to explain it very well so sorry
