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:
x = 50
Step-by-step explanation:
Given
(x + 10) + (2x + 20) = 180 ( remove the parenthesis )
x + 10 + 2x + 20 = 180, that is
3x + 30 = 180 ( subtract 30 from both sides )
3x = 150 ( divide both sides by 3 )
x = 50
