Y=mx+b
m=slope
b=y intercept
we are given (3,-1)
one solution is x=3 and y=-1 or
when x=3 then y=-1
also slope=2
so
y=2x+b
subsitue 3 for x and -1 for y and solve for b
-1=2(3)+b
-1=6+b
subtract 6
-7=b
y=2x-7 is equation
answer is number 4
Answer:
yes

Answer:
2/3,3/7,5/9.
Step-by-step explanation:
I'm sure it's the right answer
s = 71.6
____________
0.75 - 5/8s = 44
3/4 - 5/8s = 44
3/4 - 3/4 + 5/8s = 44 + 3/4
5/8s = 44 3/4
5/8s / 5/8 = 44 3/4 / 5/8
s= (179/4 / 5/8)
s= (179/4 * 8/5)
s= (179/1 * 2/5)
s= (358/5)
s= (350/5 + 8/5)
s= (70 + 8/5)
s= (70 + 1 + 3/5)
s= 71 3/5
s= 71.6
I checked this and its correct :P Sorry about the late answer, hope this helps!
Answer:
1. $0.24
2. 89.2 miles
Step-by-step explanation:
To get the unit price, divide the total price by the amount that was purchased.
1. 3.12/13 = $0.24
For the second one, get the distance traveled per hour first then multiply by 8.
22.3 / 2 = 11.15
11.15 x 8 = 89.2
