Answer:
y = -2x + 6 and y = 1/3x - 7
Step-by-step explanation:
For A, using rise over run, you can count 2 units up and 1 unit left of any given point to get to the next point. Because left is the negative direction on a graph, the 1 unit is negative. To calculate slope, divide the rise (2) over the run (-1) and substitute the slope as m into y = mx + b. In the formula, b is the y-intercept (where the line crosses the x axis). The y-intercept of A is 6, so replace b in the formula with 6:
y = -2x + 6
The slope of B is 1/3 and the y intercept is -7, so substitute those values into the formula again to get the answer for B:
y = 1/3x - 7
Answer:
I would say B
Step-by-step explanation:
when you are going down you tend to go faster because of gravity. So you would go down, up, down, up, and a little down. This would make B the answer because the speed is increasing when it goes down so that is the only answer that would make sense. Hope this helped! Have a good day! :)
Answer:
C. 2.5 or 5/2
Step-by-step explanation:
Answer:
17
Step-by-step explanation:
(x+28y)/x =50
Multiply each side by x
(x+28y)/x *x =50*x
x+28y = 50x
Subtract x
x-x+28y = 50x-x
28y = 49x
Divide by y
28y/y = 49x/y
28 = 49 x/y
Divide by 49
28/49 = x/y
We want to find
(y+28x)/y
Rewriting as
y/y +28 (x/y)
1 + 28(x/y)
Replacing x/y with (28/49)
1 + 28(28/49)
1 +28*28/49
1+784/49
1+16
17
