Which variable are you talking about? In this question x is 4 and y is 5.
Hope this helped!
Good Luck!
It’s less than because it is a negative number
The leading coefficients are opposites.
For instance
f(x) = 2x^2 + 5x + 6
g(x) = -2x^2 + 8x - 3
here the leading coefficients 2 and -2 are opposites
Adding function f(x) and g(x) gets us
f(x) + g(x) = (2x^2+5x+6) + (-2x^2+8x-3)
f(x) + g(x) = (2x^2-2x^2) + (5x+8x) + (6-3)
f(x) + g(x) = 0x^2 + 13x + 3
f(x) + g(x) = 13x + 3
The two quadratics add up to a linear equation
78.45 or 78.46 or 78.47 or 78.48 or 78.49
Answer:
$46.20
Step-by-step explanation:
We can create a proportion to find the sale on the original price. A proportion is an equation where two ratios are set equal to each other. We create two fractions using the prices and percents. If the price is discounted by 30% then we pay 70% of the price.

We begin solving by cross multiplying numerator to denominator of each fraction.
