Answer:
Step-by-step explanation:
Part A
The units on 9500 must be miles. So if x is time, then 55 must be the rate at which she travels ie 55 miles per hour. So the answer must be A.
Part B
The trip began when the time was zero. Therefore x is zero. What remains is the mileage on the odometer when x = 0. The answer must be 1950.
I would start with the standard form equation of the parallel line.
.. 5x -2y = 5(-2) -2(3) = -16
Then solve for y.
.. 2y = 5x +16 . . . add 2y+16; then divide by 2 for the next equation
.. y = (5/2)x +8 . . . . . . . corresponds to selection (B)
Answer:
2sqrt(10)
Step-by-step explanation:
Use the Pythagorean theorem.
x^2 + 3^2 = 7^2
x^2 + 9 = 49
x^2 = 40
x = sqrt(40)
x = 2sqrt(10)
Answer:
Shown below
Step-by-step explanation:
First allocate the power of three to every number
= 
not sure what you mean by positive exponents, the exponents already are positive. Maybe you mean positive exponents and integers?
Slope is 4/3, y intercept is 2, equation is y=4/3x +2
