The mistake Jadyn made in the long division is

Mistake in subtraction
the first quotient

<h3>What is long division ?</h3>

Long division refers to a way of dividing large numbers

performing the long division correctly gives

divisor dividend quotient multiplication subtraction new dividend

8 335 40 8 * 40 = 320 335 - 320 15

8 15 1 8 * 1 = 8 15 - 8 7

8 70 0.8 8 * 8 = 64 70 - 64 6

8 60 0.07 8 * 7 = 56 60 - 56 4

8 40 0.005 8 * 5 = 40 40 - 40 0

The quotient is then added as

40 + 1 + 0.8 + 0.07 + 0.005 = 41.875

Answer:

Part 1) $y=32.5x+11.95$

Par 2) see the explanation

Part 3) $\$401.95$

Step-by-step explanation:

Part 1) Write an equation in slope intercept form to represent this problem

Let

x ----> the number of tickets

y ---> the total cost

The linear equation in slope intercept form is equal to

$y=mx+b$

where

m is the slope or unit rate

b is the y-intercept (one-time processing fee)

In this problem we have

$b=\$11.95$

ordered pairs (4,141.95) and (7,239.45)

Find the slope

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

substitute the values in the formula

$m=\frac{239.45-141.95}{7-4}$

$m=\frac{97.5}{3}$

$m=32.5$

substitute the values in the linear equation

$y=32.5x+11.95$

Part 2) What does your slope represent in this problem? What does your y-intercept represent in this problem?

a) The slope of the linear equation represent the unit rate, so the slope represents the cost of one ticket

$m=\$32.5\ per\ ticket$

b) The y-intercept is the value of y when the value of x is equal to zero

In this context, the y-intercept represent the one-time processing fee

$b=\$11.95$

Part 3) Use the equation to find how much Alan would have to pay for 12 tickets

For x=12 tickets

substitute in the linear equation

$y=32.5(12)+11.95$

$y=\$401.95$

2. If x=2, y=3 find value of x²-5y+2

Damm [24]

Answer:

-9

Step-by-step explanation:

Substitute the give values into the correct place in the equation.

Since x=2, y=3,

Place "2" in the x of the equation, and "3" into the y of the equation.

x²-5y+2

= 2² - 5(3) + 2

= 4 - 15 + 2

= -9
