Ok so idk if I'm right but y= -2x+21
Answer:
C. 5/7
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
The solution to a systems of equations is the intersection point of the lines. If no solution is possible then their is no intersection point. The lines must be parallel.
Answer:
I am not sure how your teacher wanted you to estimate the answer but I solved it for you. Hopefully this helps.
Step-by-step explanation:
7x-y=7
x+2y=6
14x-2y=14
x+2y=6
add both equations
15x=20
x=20/15
x=4/3
x+2y=6
4/3+2y=6
2y=6-4/3
2y=18/3 -4/3
2y=14/3
divide both sides by 2
y= 14/3 divided by 2
y=14/3(1/2)
y=14/6
2y=
Answer:
y = 6x - 24
Step-by-step explanation:
Slope intercept form: y = mx + b.
Fill in x, y, and the slope to solve for b as follows:
First find the slope.
60 - 6
14 - 5
54/9
Slope = 6
y = 6x + b
(6) = 6(5) + b
6 = 30 + b
Subtract 30 from both sides.
-24 = b
y = 6x - 24
