Perhaps you miswrote the question because in your second equation there is no x variable. However, I inferred that you meant to write -4x+y=1, and was able to solve this system of equations. You can do this either by the substitution method or the graphing method, of which I used the latter. The solution to this system of equations is (0,1). Best wishes! c:

Hope this helps btw you have to multiply.
Answer:
if you plug in 100 and 121 in the function, it equals 10 and 11.
Therefore your avereage rate of 1
Step-by-step explanation:
C. (4,-7)
y=2x-15
-7=2(4)-15
4x+3y=-5
4(4)+3(-21)=-5
Answer:
460
Step-by-step explanation:
This quiz is Said to consist of 920 questions. Each if these questions have 2 options of answering them only. Which is True or False.
True represents correct = 0.5
False represents wrong = 0.5
The probability of correct is = 0.5
With a sample size of 920
Mean = no
= 920x0.5
= 460
So the mean number of correct answer from this calculations I just did is equal to 460
