15 POINTS!<br> What is the correct answer for Dean's problem? Explain where he went wrong.

prohojiy [21]

Answer:

The slope is 5/-2.

Step-by-step explanation:

Slope is y1-y2 over m1-m2 (rise over run). The first ordered pair is -2 (m1) and 11 (y1). We then subtract the second ordered pair (4 (m2) and -4 (y2)) from the first.

11 - (-4) = 11 + 4 = 15

-2 - 4 = -6

Remember, slope is rise over run (y over x), so the slope is 15/-6. Now, we must simplify. 15/-6 = 5/-2

Dean went wrong because he thought that slope was run over rise (x over y). If he had switched the two numbers, his answer would have been correct.

Write a linear equation that represents the cost of buying T-shirts from Paula’s Printing. Identify the meaning of each variable

vivado [14]

Answer:

$y=21.50x$

Step-by-step explanation:

Let

x ----> the number of t-shirts

y ----> the cost of buying T-shirts from Paula’s Printing in dollars

take two points from the given data

we have

(2,43) and (4,86)

step 1

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

$m=\frac{86-43}{4-2}$

$m=\frac{43}{2}=\$21.50\ per\ t-shirt$

step 2

Find the equation of the line in point slope form

$y-y1=m(x-x1)$

we have

$m=21.50$

$(x1,y1)=(2,43)$

substitute

$y-43=21.50(x-2)$

step 3

Convert to slope intercept form

$y=mx+b$

Isolate the variable y

$y-43=21.50x-43$

$y=21.50x-43+43$

$y=21.50x$

This linear equation represent a proportional relationship (the line passes through the origin)

Solve and explain please

Leokris [45]

Therefore the inequality is x≤11

and maximum I can withdraw 11 bills.

Step-by-step explanation:

Given ,

Current balance $320

Minimum balance $100

I could spent =$(320-100) = $220

Let the number of bills be x.

Total amount of x bills = $20x

According to the problem,

20x≤ 220

⇔x ≤ $\frac{220}{20}$

⇔x≤11

Therefore the inequality is x≤11

and maximum I can withdraw 11 bills.
