Get a calculator it will help girl get on an app or sum it help a lot I've done it
Answer:
A. Vertex is ( -1, 16)
B. Do they mean y-intercept for vertical intercept? That is (0,14)
C. X-intercepts are
(-3.838, 0) and (1.828, 0)
Step-by-step explanation:
plug the equation into desmos. It will graph and give you the info.
To find y-int, plug in 0 for x. This gives you the point 0, 14.
You can also use the quadratic equation to find the x-intercepts.
If we take S=3, and R=2, then the answer is C, since 3*3*2 = 18, and 3+3+2 = 8, and 8 != 18
Firstly: 3.3/4=15/4 h
She can walk 15÷(15/4)=4km in one hour
4*0.5=2km
So this woman can walk 2km within half an hour.
