Answer:
x-intercept: -2 y-intercept: 4
Step-by-step explanation:
x-intercept is where the line intersects on the x-axis
y-intercept is where the line intersects on the y-axis
Using a system of equations, it is found that Debbie worked 45 hours during the week.
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are:
- Variable x: Amount of hours worked by Juan.
- Variable y: Amount of hours worked by Debbie.
Juan and Debbie each earn 9 per hour at their "jobs", and earned a total of 765 for the week, hence:
9x + 9y = 765
Simplifying the expression by 9:
x + y = 85 -> x = 85 - y.
Debbie worked five hours more than juan during the week, hence:
y = x + 5.
Since x = 85 - y, we replace in the expression:
y = 85 - y + 5.
2y = 90.
y = 45.
Debbie worked 45 hours during the week.

Answer:
4 cm
Step-by-step explanation:
x^2 = bh
b = 2x
h = x-2
x^2 = (2x)(x-2)
4^2=[2(4)][4-2]
16 = 16
