Answer:
x + x = 10
x - x = 5
2x = 10
x = 10/2
x = 5
Step-by-step explanation:
They are both equal to y so you can set them equal to each other to solve for x:
14x - 6 = -4x + 48
18x = 54
x = 3
To solve for y just plug 3 into the x of one of the given equations
y = 14(3) - 6
y = 42 - 6
y = 36
To check:
36 = 14(3) - 6
36 = 42 - 6
36 = 36
36 = -4(3) + 48
36 = -12 + 48
36 = 36
Hope this helped!
Answer:
x = 5 , y = 2
Step-by-step explanation:
5x + 2y = 29 ....................(1)
x + 4y = 13 Multiply this equation by -5:-
-5x - 20y = -65.................(2)
Add equations (1) and (2):-
-18y = -36
y = 2
Substitute for y in equation (1):-
5x + 2(2) = 29
5x = 25
x = 5
Check the results in the second equation:-
x + 4y = 13
5 + 4(2) = 13 - It checks out.
For that problem, they give you y/z
y=-6
z=-20
So you plug that in (-6/-20). This simplifies to 3/10
ANSWER
B.
EXPLANATION
The given functions are:
f(x)=x+6
and
We want to find
This is the composition of functions, where one function becomes the input of the second function.
We plug in x+6 into the expression for g(x) to obtain,
The correct answer is B.
