To find x intercept ,
let f(x) = y
therefore y= 8x - 4
in solving for x intercept, me plug in y = 0
thus
8x - 4 =0
solving for x
8x = 4
dividing through by 8
8x/8 =4/8
x =4/8
x =1/2
therefore, the x intercept is 1/2
Answer:
The total cost to install the 1,200 ft of the pipe is $21000.
Step-by-step explanation:
Consider the provided information.
You buy 900 ft pipe with a cost of $15 per foot and the remaining 300 ft pipe with a cost of $25 per foot.
Therefore, the total cost is:
Hence, the total cost to install the 1,200 ft of the pipe is $21000.
26 pounds
Because
E is the objects gravity in earth
M objects gravity on moon
E=km
Or
90=15k
90/15=15k/15
6=k
156=6m
156/6 =6m/6
26=m
Have a great day
