Answer:
Step-by-step explanation:
julia : 20 miles in 1.2 hrs = (20/1.2) = 16.67 miles per hr
katie : 20 miles in 1.6 hrs = (20 / 1.6) = 12.5 miles per hr
how much faster does julia ride then katie...
16.67 - 12.5 = 4.17 rounds to 4.2 miles per hr faster <==
X<-7 so the answer would be greater*
The equation youre using is y=mx+b
b is the y int which 3 and the slope between the points is 5/2 so your equation is y=5/2x+3
Answer:
Step-by-step explanation:
2x² - 7x - 3 = 1
Step 1: 2x² - 7x - 4 = 0
Step 2: incorrect.
Use Quadratic Formula to solve for roots.
x = [7 ± √(7² – 4·2(-4))] / [2·2]
= [7 ± √81] / 4
= [7 ± 9] /4
= -0.5, 4
