Step-by-step explanation:

Set your -2x+10y=5 equation equal to y

-2x+10y=5

-10y -10y

-2x=5-10y

-5 -5

-2x-5+-10y

-10 -10 -10

-1/5x-1/2=y

Now you can put your equations into your graphing calculator and examine the lines made

You are purchasing books summer reading for $4.50 each. Part A: Your total cost, C, depends on,The input is,and the output is,Pa

Crazy boy [7]

Answer:

Part A) see the explanation

Part B) $C(12)=\$54$

Step-by-step explanation:

Part A)

we know that

A relationship between two variables, x, and C, represent a proportional variation if it can be expressed in the form $k=\frac{C}{x}$ or $C=kx$

Let

C ---> is the total cost (represent the output or dependent variable)

x ----> is the number of books (represent the input or independent variable)

In this problem

we have a proportional relationship between the variables x and C

Part B) we know that

The linear equation is given by

$C=kx$

The constant of proportionality k is the same that the slope or unit rate of the linear equation

In this problem the constant k is given

$k=\$4.50\ per\ book$

$C=4.50x$

For x=12 books

substitute in the equation and solve for C

$C=4.50(12)=\$54$

In function notation

$C(12)=\$54$

James can jog twice as fast as he can walk. He was able to jog the first 9 miles to his grandmother’s house, but then he tired a

ipn [44]

Let the speed of walking of James = x mile/hour

speed of jogging = 2x mile/hour

9/2x + 1.5/x = 2

or, (9 + 3)/2x = 2

or, 12 = 4x

or, x = 3

Average speed of walking = 3 mile/hour

Average speed of jogging = 2 * 3 = 6 mile/hour
