Answer:
x-intercept: 2.8 hours
y-intercept: 0.7 . . . . fraction of power remaining
Step-by-step explanation:
The equation is in slope-intercept form, so the y-intercept can be read directly: 0.7.
To find the x-intercept, set y=0 and solve for x:
0 = -0.25x +0.7
0.25x = 0.7 . . . . . add .25x
x = 2.8 . . . . . . . . . multiply by 4 (that is, the reciprocal of 0.25)
The x-intercept is 2.8; the y-intercept is 0.7.
Answer:
79200ft/1 hour
Step-by-step explanation:
Formula
multiply the length value by 5280
1, 2, 4, 7, 14, 28
You can look at it as
1 x 28 = 28
2 x 14 = 28
4 x 7 = 28
hope this helps :)
Step-by-step explanation:
2(x-9) = 9 (- 1/3)
2x-18=-3
2x=18-3
x=15/2
x=7.5
