Write an equation that is perpendicular to y= 1/2x+5 and passes through (4,8)

Answers

Answer 1
Answer:

Answer:

y = -2x + 16.

Step-by-step explanation:

The slope of the perpendicular line = -1 / slope of the given line

= -1 / 1/2 = -2.

Using the point slope form of the equation of a straight line:

y - y1 = m (x - x1)

y - 8 = -2(x - 4)

y - 8 = -2x + 8

y = -2x + 16  is the required equation.

Skylar makes turkey sandwiches for a family reunion he purchases 5 lbs. 4 oz. of sliced turkey for $26.88 what is the unit cost per ounce for turkey skylar purchased

Answers

Answer:

$0.32

Step-by-step explanation:

The first step is to convert pounds to ounces.

1 lbs = 16 oz

so:

5 lbs = 5(16) ounces

5 lbs = 80 oz

Skylar bought 5 pounds and 4 ounces, and we already found that 5 pounds is 80 ounces, so she bought a total of

80oz + 4oz = 84 oz.

The price for these 84 ounces was $ 26.88, to find the unit cost per ounce of turkey, we divided the total cost by the amount of ounces:

$26.88 ÷ 84 = $0.32

the cost per ounce is $0.32
