Maria has made $28 selling bracelets at a craft fair. She spends $52 on supplies to make the bracelets. She sells each bracelet
Ray Of Light [21]

Answer: D. 3x +28 > 52

Step-by-step explanation:

Based on the information given, the inequality that Maria can use to find how many more bracelets she needs to sell to make more money than she spent on supplies will be calculated thus:

With the question above, the total sales must be greater than the amount spent on supplies. Let the number of bracelets that needs to be sold be represented by x.

Therefore, (3 × x) + 28 > 52

= 3x + 28 > 52.

We can calculate further

3x > 52 - 28

3x > 24

x > 24/3

x > 8

Therefore, 9 or more bracelets needs to be sold since x is greater than 8.

Therefore, the correct option is D 3x +28 > 52

A-line includes the points (8,9) and (9,1). What is its equation in point-slope form?
sergij07 [2.7K]

Answer:

y-(9)=(-8)(x-8)\\

Step-by-step explanation:

(x_1, y_1) = (8, 9)\\(x_2, y_2) = (9,1)\\

Step one: Find the slope (m)

slope=m=\frac{rise}{run} =\frac{y_2-y_1}{x_2-x_1} = \frac{1-9}{9-8} =\frac{-8}{1} =-8

Step two: Plug your known values into the point-slope equation

m=-8\\y_1=9\\x_1=8\\

Point-slope form is y-y_1=m(x-x_1)

y-(9)=(-8)(x-8)\\

If you want to convert point-slope form to general form, isolate for y.

y-9=-8x+64\\y=-8x+73
