Apply the markup or markdown to each item and then find the retail sale price of the following items. ​Round to two decimal places. Question:

$2.99 picture frame; 100% markup

Answers

Answer:

5.98

Step-by-step explanation:

2.99 * 1= 2.99

2.99+2.99= 5.98

First you had to multiply 2.99 by 1 because 100% in decimal is 1.

You get 2.99 and you add it to the original price.

And that is how you get 5.98

5.98 because 100% is 2.99 then add them together

Abe has 150 t-shirts to sell before the playoffs begin. The table shows the linear relationship between the number of t-shirts remaining, y, and the number of days he has been selling, X. T-shirt Sales Number of Number of Days T-shirts Remaining х

Which function can be used to find y, the number of t-shirts remaining after x days?​

Answers

Answer:

Y= -12x + 150

Step-by-step explanation:

1. You do the change in y over the change in x to get the slope.

y1 - y2 / x1 - x2 and you get the slope of -12

2. Making a point-slope form equation

y-y1=m(x-x1)

y-138= -12(x-1)

3. Turning point-slope form equation to slope-intercept

y-138= -12(x-1)

distributive property

y-138=-12x+12

add 138 on both sides

y= -12x+150

A) Substitute 7 for a.
B) Pick any value for a and substitute.

C) Simplify the equation after substituting the value for a.

Find the equation of the line that is
perpendicular to the line y = 2x 5. (If you solve this I’ll make you brain list)

Answers

Answer:

y = ½x + 6.

Step-by-step explanation:

You get y = -2x +5, so the slope is –2. Perpendicular lines have opposite-reciprocal slopes, so the slope of the line we want to find is 1/2. Plugging in the point given into the equation y = 1/2x + b and solving for b, we get b = 6. Thus, the equation of the line is y = ½x + 6.

y=-1/2x+6
