You add five to each product when you multiply numbers by five. if 5x10 is 50, 5x11 is 55. so 5x 12 would be 60 because 55+5=60
85/136 x 100 = 8500/136 = 62.5%
Answer:
Step-by-step explanation:
As written, they all are linear functions.
If we assume that x3 is supposed to be interpreted as x³ = x^3, and that x2 is supposed to be x² = x^2, then the equations containing those terms are not linear equations.
The equation y = 1/5x is usually interpreted to mean y = (1/5)x. If it is intended to be y = 1/(5x), then it is not a linear function either.
___
A linear function is a sum of terms that are either constant or containing a single variable to the first power.
The fraction of 12% is 3/25ths and the decimal to 12% is 0.12
A) When the relation is inverse, the product of the two related values is a constant. Here we have
n·c = 4·312
n·c = 1248 . . . . an equation relating n and c
You can rearrange this to
c = 1248/n
B) Using 6 for n, we have
c = 1248/6 = 208
The cost per person decreases from 312 to 208, so decreases by $104.
