Number of questions worth 5 points = 10
Number of questions worth 2 points = 25
Further explanation:
The given system is a system of linear equations in two variables.
We will use the subsitution method to solve the system
Given equations are:

From equation no 1:

Putting x=35-y in second equation

Hence,

Answer:
1 hour and 15 minutes
or
1.25 hr.
Step-by-step explanation:
40 miles ⇒ 1 hr.
50 miles ⇒ total hours
= 1.25 hours
Simple ....
we know to find slope is (y1-y2)/(x1-x2)
if we plug in what we know......
(-8,-6),(2,-3)
(-6--3)/(-8-2)
it turns into...
(-6++3)/(-8+-2)
(-3)/(-10)= 3/10
Thus, your answer is that she made no mistake. (C)
It's is a square and you know just by graphing it
