Step-by-step explanation:
I’m not sure what h and t are but you would want to plug them in and solve. How I would do it is multiply h and t on the left, then multiply t squared and get an answer, then multiply that answer by -5, then multiply t by 20. Next add or subtract all of the numbers on the right and I think you would get your answer.
Hello! The formula for finding slope is y2- y1 / x2- x1. That means subtract the first y-coordinate from the second y-coordinate and the first x-coordinate from the second x-coordinate. Plug in the values to have it like this: -1 - 4 / 2 - (-3). When you subtract the numbers, you get -5/5 or just simply -1. The slope of the line is -1.
Option D is correct.
You can tell by observing that triangles ACD and BCD are congruent: they are both right triangles (because CD is perpendicular to AB) with a leg in common (CD) and the other leg congruent (AD = BD because CD bisects AB).
So, they must have the same hypotenuse as well, i.e. AC = BC
The slope would be B) -1/2
Because it is going down by one unit and 2 to the right
