Y varies directly with x. If x = 16 and y = 2 find y when x = 96
ArbitrLikvidat [17]

Answer:

y = 12

Step-by-step explanation:

Use the equation y = kx

Plug in x and y to find k:

2 = k(16)

1/8 = k

Then, plug in 1/8 as k and 96 as x to find y:

y = 1/8(96)

y = 12

Given the function<br> Calculate the following values:<br> f( - 1) =<br> f(0)<br> f(2)=
Alecsey [184]

-1 is less than 0, so you use the first equation:

3(-1) +2 = -3+2 = -1

f(-1) = -1

For 0 use the 2nd equation:

3(0) + 4 = 0+4 = 4

f(0) = 4

For 2 use the 2nd equation:

3(2) + 4 = 6+4 = 10

f(2) = 10

A company is selling toothpicks. It costs $0.03 to produce each toothpick and a fixed cost of $110 a month for the company. If t
AlexFokin [52]
<h3>11,000 toothpicks must be sold in order to break even.</h3>

Step-by-step explanation:

Here, let us assume the number of toothpicks sold to break even = m

So, for m toothpicks, Total cost  = Total Earnings

Now, the cost of producing 1 toothpick = $0.03

So, cost of production of m toothpicks  = m x ( cost of 1 toothpick)

= $(0.03 m)

Also, fixed month cost  = $110

So, Total cost of production = $110 + $0.03 m  .... (1)

Again, the selling cost of 1 toothpick = $0.04

So, selling cost of m toothpicks  = m ( cost of 1 toothpick)   = $(0.04 m)  ..(2)

From (1) and (2)

110 + 0.03 m = (0.04 m)

⇒ 110 = 0.01 m

or, m  = \frac{110}{0.01}  = 11,000

⇒ m = 11,000

Hence, 11,000 toothpicks must be sold in order to break even.
