Step-by-step explanation:
To determine if (3, 1 ) is a solution to the system
Substitute x = 3 into both equations and evaluate. If the result is y = 1 for both then the point is a solution.
y = 
× 3 - 3 = 4 - 3 = 1
y = - 2(3) + 7 = - 6 + 7 = 1
Since both equations equal 1 then
(3, 1 ) is a solution to the system
It’s either the first one or the last one, most likely none of the answers are correct

Step-by-step explanation:
Raising her rate by 15% is equivalent to adding 15% of what she charged before to the original price.
Answer:
b = -80
Step-by-step explanation:
-16 = 0.2b
Divide both sides by 0.2
We have , -16/0.2 = 0.2b/0.2
Therefore, b = -80
