Answers

Get the slope of the line using the two known points:

slope = (7 3/4 - 6 1/4) / (1 1/4 - 3/4) = (1 2/4) / (2/4) = 3

Use the point-slope formula for a line to get the equation of the line. You can use any of the known points and the slope computed above. For example,

y - 6 1/4 = 3 (x - 3/4)   ⇒   y = 3x + 16/4 = 3x + 4

Then for some given value of x, the third point has y-coordinate 3x + 4.

"Which values" suggests there may be more to the question, namely some list of answer choices. If you have something like that, just check if the above condition is met.

The answer to your question is y=3x+4

The markup percentage regarding the sale of the good will be 136%.

How to calculate the percentage?

From the information given, the initial cost is $55.00 and the new price is $130.19. The increase in percentage will be:

= (130.19 - 55)/55 × 100

= 75.19/55 × 100

= 136%

Therefore, the markup percentage regarding the sale of the good will be 136%.

Answers

Answer:

A. 12 square feet

Step-by-step explanation:

So it's easier to find the area when you split the shape into 2 parts, and they already did that for you. So basically you find the area of both triangles and add them together. The formula for a triangle is base x height divided by 2. You don't have to do that because there are 2 triangles with the same base and height so you don't have to divide it by 2. 3 x 4 = 12, so A. 12 square feet is your answer.

the answer is A.) 12 square feet
