Basically f(x)=5x means whatever number you plug in will be your x coordinate, and the result will be your y coordinate.
(1,5) (2,10) (3,15) (4,20) and so on. 1,2,3 and 4 are x coordinates plugged into the equation, the y coordinate is whatever 1,2,3 and 4 multiplied by 5 is.
Answer:
57.6
Step-by-step explanation:
If hê works 15 grades in 24 min how long hê will take to finish 36 grades
15 grades= 24 min
36 grades=?
Cress cross
15grades?=24min x 36grades
15 grades?=864 min grades
15grades/15grades?=864mingrades/15grades
?=57.6 min
Answer:
n
Step-by-step explanation:n
Let x = amount invested at 8%
26000 - x = amount invested at 6%
0.08x + 0.06(26000 - x) = 1860
solving the equation you get x = 15000
and subtract that from 26000 you get 11000
8% investment = 15000
6% investment = 11000
