(16pts) ()=^2+4. ()=(+4). ℎ()=(−1)^2
Determine how many solutions each has.

Find the slope of the line that contains the following points. r(-2, 4), s(6, -2)

Follow these steps using the algebra tiles to solve the equation −5x + (−2) = −2x + 4. 1. add 5 positive x-tiles to both sides and create zero pairs. 2. add 4 negative unit tiles to both sides and create zero pairs. 3. divide the unit tiles evenly among the x-tiles. x =

The height of a plant, in inches, p years after planting it is given by the polynomial function r(p) = -2p% + 270p. find the height of the plant when p = 90 years.
