Answer:
See below.
Step-by-step explanation:
To find the other two points such as the x-intercepts, set the equation equal to 0 and solve for x.

This means the points will be at (3.64, 0) and (-1.64, 0).
This graph is shifted 1 unit to the right and 7 units down from x^2.
Answer:
Step-by-step explanation:
Lifeguard=x
tutor=35-x
7x+10(35-x)=290
7x+350-10x=290
-3x=-60
x=20 hours as a lifeguard ($140)
35-x=15 hours as a tutor ($150)
adds to $290.
Hope that helps! :)
