Answer:
2x + y = 7
 x=7/2
 y=7
Step-by-step explanation:
to find y itercept =0
to find x intercept=0
 
        
             
        
        
        
Step-by-step explanation:
using the formula :
2.d.s = V²-Vo²
2(-0.15) (60) = V² - (8.55)²
-18 = V² - 73.1
V² = 73.1 - 18
V² = 55.1
=> V = √55.1 = 7.4
so, the velocity when she ends the race =
7.4 m/s
 
        
             
        
        
        
Answer:
y= 1,000x+55,000
Step-by-step explanation:
55,000 is y intercept. 1,000x is slope.
