Parallel = same slope
Y = -3x + 7, the slope is -3
Slope intercept form: y = mx + b
Y = -3x + b
Plug in point (2,-4) and solve for b
-4 = -3(2) + b
-4 = -6 + b, b = 2
Solution: y = -3x + 2
The answer is D

6. For a particular pickup truck, the percent markup is known to be 115% based on cost to the seller. If the seller paid $15,800

Neko [114]

Answer:

53.5 %

Explanation:

You can convert the percent markup into a multiplicative factor in this way:

Base price: 15,800 . . . (cost to the seller)

Percent mark up: 115% . . . (based on the cost to the seller)

Sale price: 15,800 + 115% of x = 15,800 + 115 × 15,800 /100 =

= 15,800 + 1.15 × 15,800 = 15,800 (2.15) = 33,970

The markup is:

Markup = price paid by the seller - cost to the seller = 33,970 - 15,800 = 18,170 (notice that this is 115% of 15,800)

And the percent markup based on the sale price is:

% = (markup / sale price) × 100 = (18,700 / 33,970) × 100 =

= 53.49 %

Rounding to the nearest tenth percent that is 53.5 %.

Stephanie had a total of 80 pieces of $ 2 and $ 10 notes. After spending 2/5 of her $ 2 notes and 8 pieces of her $ 10 notes, sh

Ghella [55]

Answer:

$440

Step-by-step explanation:

notes $2 - n

notes $10 - m

n + m = 80 ----------> m = 80 - n

1 - 2/5 = 3/5

$\frac{3}{5} * n = m - 8$

$\frac{3}{5} * n = 80 - n - 8 \\\\\frac{3}{5} * n + n = 72\\\\\frac{8}{5} * n = 72\\n = 45 \\m = 35\\$

45 * $2 + 35 * $10 = 90 + 350 = $440
