Answer:

14x - 9 + 8x + 3 = 9x - 8 - 3x - 14
Combine like terms:
14x + 8x - 9 + 3 = 9x - 3x - 8 - 14
22x - 6 = 6x - 22
Subtract 6x from both sides:
22x - 6x - 6 = 6x - 6x - 22
16x - 6 = -22
Add 6 to both sides:
16x - 6 + 6 = -22 + 6
16x = -16
Divide both sides by 16:
16x/16 = -16/16
x = -1. There is only one solution to this equation.
Answer: it is (-2) because rise over run
When a line is represented in the slope intercept formula as in the question you must remember that it is always set up like so...
y = mx + b
m is the slope and b is the y-intercept of the line
Since in the equation y = -3x + 1 the m is -3 then the slope is -3

We know that the diameter of the wheel is 80cm. Thus we can find the circumference of the wheel by the equation C=2(pi)r or, knowing that the Diameter is 2r, C=D(pi).
Now, we know that the circumference of the wheel is 80(pi)cm.
If the wheel rotates 170 times, that means we multiply the circumference of the wheel by 170 to receive the answer.
80 x 170 x pi = about 42725.66cm
we then can divide our answer by 100 to convert to meters -->
(42725.66cm)(1m/100cm) = 427.2566 which we round to 427m
