Given f(x) = -5x + 1. What is f(-3)?
babunello [35]

Answer:

f(-3) =16

Step-by-step explanation:

f(x) = -5x + 1

f(-3) means let x=-3

Substituting x=-3 into the equation

f(-3) = -5 (-3) +1

Multiplying -5 and -3

f(-3) = 15+1

f(-3) =16

A student has $1 bills and $5 bills in his wallet. He had a total of 15 bills that are worth $47. How many of each type does he
Mrrafil [7]

Total number of $1 bills=7

Total number of $5 bills=8

Further explanation:

Given

Let x be the number of $1 bills

and

y be the number of $5 bills

Then according to the given statements

x+y=15

x+5y=47

From first equation:

x+y=15\\x=15-y

Putting x=15-y in second equation

x+5y=47\\15-y+5y=47\\4y=47-15\\4y=32\\\frac{4y}{4}=\frac{32}{4}\\y=8

Putting y=8 in first equation

x+8=15\\x=15-8\\x=7

Hence,

Total number of $1 bills=7

Total number of $5 bills=8
