Answer:
x=2, y=1
Step-by-step explanation:
2x + y = 5
5x − 2y = 8.
Multiply the first equation by 2
2( 2x + y) = 5*2
4x +2y = 10
Add this to the 2nd equation to eliminate y
4x+2y = 10
5x -2y = 8
--------------------
9x = 18
Divide by 9
9x/9 = 18/9
x = 2
Now find y
2x+y = 5
2(2)+y = 5
4+y = 5
Subtract 4 from each side
y = 5-4
y =1
Answer:
What is the question
Step-by-step explanation:
Answer: A) y = 7x
<u>Step-by-step explanation:</u>
In order to be a proportional relationship, the equation MUST pass through the origin (0, 0) and only contain two coordinates
A) 0 = 7(0) ---> 0 = 0 TRUE
B) 0 = 2 + 3(0) ---> 0 = 2 False
C) 0 = Vz(0) ---> Too many variables so False
D) 0 = 5 - 0 ---> 0 = 5 False
Answer:
B 10 pounds
Step-by-step explanation:
