Answer: X and Y are variables which means they represent some number that you don't know. When you are working with Graphs, X and Y could be coordinates. When it wants you to solve for x you have to do the inverse opperation until you isolate the variable you are trying to solve. Basically, inverse opperations are if it is -30 on one side you would add 30 to both sides to cancel it out. When you isolate the variable it is only that one letter with everything else on the other side.

F(x) = 5x-2, find f(-3/5) what is the output of the given input

Natasha_Volkova [10]

F(x) = 5x - 2
f(-3/5) = 5(-3/5) - 2
f(-3/5) = -15/5 - 2
f(-3/5) = -3 - 2
f(-3/5) = -5

Part of the proceeds from a garage sale was $470 worth of $10 and $20 bills. If there were 14 more $10 bills than $20 bills, fin

Brums [2.3K]

There are 25 $10 bills and 11 $20 bills.

Step-by-step explanation:

Given,

Worth of proceeds from garage = $470

Let,

x be the number of $10 bills

y be the number of $20 bills.

According to given situation;

10x+20y=470 Eqn 1

x = y+14 Eqn 2

Putting value of x from Eqn 2 in Eqn 1

$10(y+14)+20y=470\\10y+140+20y=470\\30y=470-140\\30y=330$

Dividing both sides by 30

$\frac{30y}{30}=\frac{330}{30}\\y=11$

Putting y=11 in Eqn 2

$x=11+14\\x=25$

There are 25 $10 bills and 11 $20 bills.
