Answer:
probably 2 or 4
Step-by-step explanation:
In order to utilize the graph, first you have to distinguish which graph accurately pertains to the two functions.
This can be done by rewriting the equations in the form y = mx + b which can be graphed with ease; where m is the slope and b is the y intercept.
-x^2 + y = 1
y = x^2 + 1
So this will be a basic y = x^2 parabola where the center intercepts on the y axis at (0, 1)
-x + y = 2
y = x +2
So this will be a basic y = x linear where the y intercept is on the y axis at (0, 2)
The choice which depicts these two graphs correctly is the first choice. The method to find the solutions to the system of equations by using the graph is by determining the x coordinate of the points where the two graphed equations intersect.

Answer:
She worked 12 hours for the week
Step-by-step explanation:
Given that :
Hours worked :
Mondays = 40 hours
Tuesdays = 8 hours
If 1/4 of regular hours was worked in a certain week, the number of hours worked that week can be calculated thus ;
1/4 (Monday hours + Tuesday hours)
1/4(40 + 8)
(1/4 * 40) + (1/4 * 8)
10 + 2
= 12 hours
If you multiply 8.5 by 50 cents your answer will be 4.25
