Answer:
x = 15/p
Step-by-step explanation:
4(px + 1) = 64
4px + 4 = 64
-4 -4
4px/p = 60/p
4x/4 = 60/p/4
x = 15/p
Answer:
y=2x+8
Step-by-step explanation:
Alright so, to find the equation, we need to find the slope first. We can do that by turning the input and output into coordinates.
(1,10) and (2,12)
To find the slope, we do:

Which equals to 2
So right now we can say that the equation is:
y=2x+b
In order to find b, the constant, we just need to plug in the y values and x value of a coordinate:
10=2(1)+b
10=2+b
8=b
So now we can say that the equation is:
y=2x+8
Answer:
Step-by-step explanation:
Solve simultaneously
-5x-3y=9
4x-187-54=0
4x=241
x=60.25
To get y
Substitute for x in equal one
-5(60.25)-3y=9
-301.25-3y=9
-3y=9+301.25
-3y=310.25
y=-103.4
Provided his $100 budget is for millage only
100/22= $4.54 per day for miles
4.54/0.27= 16.835 miles per day
