Answer:
Option C
Step-by-step explanation:
we have
x+2y=2 ------> equation A
-4x+4y=-8 ------> equation B
Multiply equation B by -1 both sides
-1(-4x+4y)=-8*(-1)
4x-4y=8 -----> equation C
Adds equation A and equation C
x+2y=2
4x-4y=8
--------------
5x-2y=10 ----> equation D
An equivalent system of equations is equation A and equation D
so
x+2y=2 ------> equation A
5x-2y=10 ----> equation D
Answer:
(1,-4) and (3,-5)
-4+5/1-3
1/-2 , so the slope is -1/2
Y intercept is -3.5
ANSWER IS y=-1/2x-3.5
THANKSS :)
Answer:
just one solution
Step-by-step explanation:
4x + 8 = −2 − 2 + 5x
4x - 5x = -2 - 2 - 8
x = 12
Simple multiplication..
24 * 24.75 = $ 594.00 <== their total value
Answer:
- The slope is 1/2
- The equation that represents this function is x -2y = 2
Step-by-step explanation:
<em>Intercepts</em>
The table shows the x-intercept to be (2, 0), and the y-intercept to be (0, -1). These are not matched by any of the answer choices.
<em>Slope</em>
The slope is ...
slope = (change in y)/(change in x) = (0 -(-1))/(2 -0) = 1/2
<em>Equation</em>
You can choose the equation by seeing if it works for a couple of points. You know the last equation is incorrect, because that slope-intercept form has the y-intercept as +1, not -1.
