Taya2010 [7]4 years ago
3 0

Answer:

x= (y+2)/5

Step-by-step explanation:

Let f(x) = y

y = 5x -2

Adding 2 on both sides

y +2= 5x

Divinding by 5 in both sides

(y+2)/5 = x = f*(x)

Therefore,

f*() = (y+2)/5

.

Hope this helps you...

Answer:

20%

Step-by-step explanation:

Step 1: Subtract starting value minus the final value (decrease)

\$5.75 - \$4.60\\\\= 5.75 - 4.60 \\\\= 1.15

Step 2: Divide the decrease by the original number

1.15 \div 5.75\\\\= \frac{1.15}{5.75}\\\\= 0.2

Step 3: Multiply the result by 100 to get a percent decrease

0.2 \times 100\\\\= 20

Therefore, the percent decrease of the price of paper per package is 20%

<em>Note: If the percentage is negative, it means there was an increase and not a decrease.</em>

I need help..... please answer ASAP if you know how to solve this

For part A, The answer is that the car gets better gas mileage. We can see it from the graph that the number of gallons used is on the X axis, and the distance traveled using those number of gallons is on the Y axis. The easiest way to compare would be to look at the 1 gallon of gas. You can see that you can travel 25 miles on 1 gallon of gas. The truck on the other hand will get you 18 miles per gallon. Imagine putting 1 in for X, the Y value would be 18 if you did this. The graph just shows us a visual way of saying the same thing. To determine how much farther the car with a girl on 8 gallons of gas, you would just multiply 8 by 25 for the number of miles traveled by the car. You would multiply 8 by 18 to find the number of miles traveled for the truck. The answers are 200 miles for the car and 144 miles for the truck. 200-144=56 miles farther for the car.

Area of rectangle = l x b

18 = l x b

Factors of 18 =

1 x 18 = 18

2 x 9 = 18

3 x 6 = 18
