Answer:
see below
Step-by-step explanation:
Order of operations is parenthesis, exponents, multiplication, division, addition, subtraction.
since there are no exponents in this problem the next step is -2(2.2)
Simplify the previous step and you get -4.4
final answer is -7.6 - 4.4 = -12
Answer:
Step-by-step explanation:
I think EFD because according to Google, "Two angles are Adjacent when they have a common side and a common vertex (corner point) and don't overlap.
"
Answer:
x+4y=-35
-8x-4y=28
Step-by-step explanation:
The answer to the original equations is (1, -9). You can solve that by using substitution by moving the 4y over and substituting that equation for x on the second part of the top equation. Using elimination, the second set of answers will give you the same, (1, -9)!
Answer:
7.13 x 10^-5
Step-by-step explanation:
We don't know what ( 5 2 , 7 2 ) is supposed to represent, but it seems unlikely that the sum of those numbers is -6. Hence that is not a solution to the system.
The sum of -4 and 10 is +6, not -6, so that point is not a solution, either.
Neither offering is a solution to the equations.
