Add these together.
You get -15y=-45
So y=3
Now plug in to first equation.
8x-8(3)=-16
8x-24=-16
8x=8 so x=1
Check both values in second equation.
-8(1)-7(3)=
-8-21=-29
It works...so x=1, y=3
the answer is d (i think) because anything aboveboard .90, whether it is positive or negative
Answer:
14 points
Step-by-step explanation:
The second test Lee did was 13 points fewer than the first test, which was 91 points, so the second test's score is 91 - 13 = 78 points.
The third test had the score of 92, so this is the highest score, and the lowest score is the second one: 78 points.
The difference between Lee's highest and lowest scores is:
92 - 78 = 14 points
Answer:
5
Step-by-step explanation:
Use PEMDAS to complete the problem
PE doesn't matter, there's not parentheses or exponents
MD=Multiplication and Division. Do 3*6=9, now your problem looks like 9-4
AS=Addition and Subtraction. 9-4=5
If u just want the quick answer it’s -i bc i^14=-1 and i^16=1
