The correct answer is-2xy if it’s subtract
Answer:
x intercept = 8
y intercept = -24
Step-by-step explanation:
In the USA, the shoe sizes or men are approximated by the equation 3f-s=24, where f represents the length of the foot in inches and s represents the shoe size.
<u>When we represent this equation using a graph, we mark the independent variable on the x axis and the dependent variable on the y axis.</u>
Here the foot length is the independent variable and the shoe size is the dependent variable. Hence we take foot length on x axis.
To get x intercept put y=0, f =
= 8 inches .
This is the point from which where we start our shoe size.
The y intercept , s = -24.
You have to use the quadratic formula to solve this. The zeros of this quadratic are 2 + sqrt2/2 and 2 - sqrt2/2, which in "real" numbers is 1.707 and .2928
