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

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

Consider this equation and the steps taken to solve it.

–9(a – 5) = –18 (distribute)
–9a + 45 = –18 (subtract 45)
–9a = –63 (divide by –9)
a = 7

What steps might you take to verify the solution? Check all that apply.

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

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

D) Verify that a = 7 is correct when the result is a true statement.

E) Verify that a = 7 is correct when the result is a false statement.

Ight everyone on i need help on part B but tell me if A is incorrect.
The elevation we call sea level is actually the average level of the sea. This means that at average sea level, the elevation is zero. In reality, the level of the sea rises and falls in what are called tides. Low tide is the point of lowest sea level in a tidal period. High tide is the point of highest sea level in a tidal period. The height above or below average sea level is called elevation. An elevation below sea level is considered a negative value, while an elevation above sea level is positive.

Winston lives near the ocean. He regularly brings an altimeter to the beach to measure the elevation of the ocean’s surface. You will use the data Winston gathered to complete tasks about the rising and falling of the ocean’s surface. When necessary, sketch a diagram of the situation on a separate sheet of paper to assist you.

On Monday at 1 p.m., when the ocean’s surface was at an elevation of 2.2 feet, Winston went to a surf shop that was 8.2 feet above the ocean’s surface. At 7 p.m. when the ocean’s surface was at an elevation of -2.4 feet, Winston ate dinner at a restaurant whose deck was 10 feet above the ocean’s surface.

Part 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.
