Step-by-step explanation:
#This is simple case of addition, who numbers and fractions:

Hence, the summation of this two fractions is 1 3/4
Answer:
-2?
Step-by-step explanation:
You find this value by factoring. Factoring finds the zeros of the function. When the ball hits the ground, it has 0 height. Therefore, when the function goes through the x axis, it has a y value of 0. That means that when y = 0, the ball has hit the ground. Use the quadratic formula to factor

. Notice I rearranged the terms. When you factor that you get zeros of -3.19 and 2.19. The two things in math that will never EVER be negative are time and distance/length. Therefore, that tells us that the ball hits the ground 2.19 seconds after it was thrown.
2 this is because it is up 2 and over 1 (rise over run) and therefore 2/1. 2/1 =2
hope i helped and you understand slope now:)
Answer:
Option A
Step-by-step explanation:
We know that the "3x ? 2" line must be positive, so it cannot be C or D. The other line is negative, so the "2x ? 5" line must be -2x. This gets rid of option B, leaving us with our answer of A!
Have a nice day!
