Rita makes and sells necklaces. The materials to make each necklace cost $2.75. Last week she made 8 necklaces and wants to make

a total profit of $78. Using the equation mc020-1.jpg, Rita determined that she needs to sell each necklace for $7 to make a total profit of $78. Which error did Rita make?

Answer:

The answer is C. The equation should be 8(x-2.75)=78, and she needs to sell each necklace for $12.50.

Rita's error is in the sign of 2.75 in her equation. If x is her selling price, Rita needs to find the value of x in
8(x -2.75) = 78

 x = 2.75 +78/8 = 12.50

What expression is equivalent to 5(x+6)-2x+9
puteri [66]

Answer: 3x - 39

Step-by-step explanation:

Distribute 5(x +6) by multiplying 5 times x and 5 times 6. Becomes 5x + 30

5x +30 - 2x +9. Combine like terms.

5x -2x +30 +9 becomes 3x +39

Which of the following is the equation of a line perpendicular to the line y=-3/2x+4, passing through the point (3, 9)?
Anastaziya [24]

Answer: -2x+3y = 21 which is choice C

============================================

Work Shown:

The slope of the original line is -3/2. The perpendicular slope is 2/3. We flip the fraction and flip the sign. Multiplying the original slope (-3/2) and the perpendicular slope (2/3) will result in -1. Let's use this perpendicular slope and the point to find the equation of the perpendicular line in slope intercept form.

y = m+b

y = (2/3)x+b .... plug in the perpendicular slope

9 = (2/3)(3)+b .... plug in the point (x,y) = (3,9)

9 = 2+b

9-2 = 2+b-2 ... subtract 2 from both sides

b = 7

So y = (2/3)x+b turns into y = (2/3)x+7.

This equation is in slope intercept form.

---------------------------

Let's convert to standard form

y = (2/3)x+7

3*y = 3*((2/3)x+7) ... multiply both sides by 3 to clear out the fraction

3*y = 3*(2/3)x+3*7 ... distribute

3y = 2x+21

-2x+3y = 21 .... get the x term to the other side (subtract 2x from both sides)
