For which values of p and q does the following equation have infinitely many solutions ? -90x+q=px+45 choose all answers that apply: a q=45q and p=-45 b q=-45q and p=45p c q=-45q and p=−90p d q=45 and p=-90p=−90

In order for the expression to have infinitely many solutions, we need to have a situation like this:

In other words, we need the left and right hand sides to be the same, so that the equality is actually an identity, and no matter which x-value you choose, the equality will hold.

In your case, if you mimic the template above, you have

And since we want , we want

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571

question: use the following table of a school bus during morning pickups to calculate its average speed between 2.8 km and 4.2 km

answer: 42 km/h

explanation: 1.4/0.033 42.42424 = 42 km/h
