Answer:
$76.80
Step-by-step explanation:
120/80 equals how many times the next route is larger than the first one. Which is 1.5 times larger.
Take the first earning of 51.20 and multiply by 1.5 to get 76.80
120/80=1.5
51.20*1.5=76.8
On the next route the truck driver earns $76.80.
As we move from the first point to the second, x increases from 2 to 10, so the change in x is 8. At the same time, y increases by 1 from 4 to 5. Thus, the slope is m = rise / run = 8/1 = 8.
Using the point-slope formula, we get y-4 = 8(x -2), or 8x - 16.
Isolate y. To do this, add 4 to both sides, obtaining:
y = 8x - 12.
This is the slope-intercept form for the equation of the line thru (2,4) and (10,5).
Answer:
C) y= -3, D) x= -1, E y= -5/4x +2
Step-by-step explanation:
Simplifying
64 + -12w = 6w
Solving
64 + -12w = 6w
Solving for variable 'w'.
Move all terms containing w to the left, all other terms to the right.
Add '-6w' to each side of the equation.
64 + -12w + -6w = 6w + -6w
Combine like terms: -12w + -6w = -18w
64 + -18w = 6w + -6w
Combine like terms: 6w + -6w = 0
64 + -18w = 0
Add '-64' to each side of the equation.
64 + -64 + -18w = 0 + -64
Combine like terms: 64 + -64 = 0
0 + -18w = 0 + -64
-18w = 0 + -64
Combine like terms: 0 + -64 = -64
-18w = -64
Divide each side by '-18'.
w = 3.555555556
Simplifying
w = 3.555555556
