Step-by-step explanation:

By the formula of slope, we have

$( \frac{y _{2} - y_{1} }{x _2 - x _{1} }) \\ ( \frac{ - 1 - 1}{ - 2 - 6} ) \\ ( \frac{ - 2}{ - 8} ) \\ ( \frac{1}{4} )$

A parent volunteer group is raising money by making custom hats to sell at school activities. They plan to sell the hats for $12

Misha Larkins [42]

Answer:

B. (12-6) n - 50

Step-by-step explanation:

Given that:

Cost of making hat = $6 per hat

Selling price = $12 per hat

Advert cost = $50

Number of hats made = n

The profit or money raised from the sales of hat:

Total Revenue from sales - total cost of production - advert cost

Total Revenue from sales = ($12 * n) = $12n

Total cost of production = ($6 * n) = $6n

Advert cost = $50

Hence,

12n - (6n + 50)

12n - 6n - 50

(12 - 6)n - 50

Graph the function f(x) = -42-4+ 5 on the axes below. You must plot the

valentina_108 [34]

Answer:

- attached graph

- Horizontal Asymptote: y = 5

- twon whole number points are (4,4) and (5,1)

Step-by-step explanation:

- Exponential functions have a horizontal asymptote. The equation of the horizontal asymptote

y = -4^(x-4) + 5

= -4^(4-4) + 5

= -4^(0) + 5

= -1 + 5

= 4

y = -4^(x-4) + 5

= -4^(5-4) + 5

= -4^(1) + 5

= -4 + 5

= 1

What is the equation of the horizontal line that passes through (-4, 6)

inessss [21]

Answer:

The answer would be y=6

Step-by-step explanation:

This is because when we are looking at horizontal lines, we look at the y-coordinate to determine a line because the y-axis is what determines height.

PLEASE HELP/ANSWER! From 1980 to 1990, Lior’s weight increased by 25%. If his weight was k kilograms in 1990, what was it in 198

Elena-2011 [213]

The weight in 1980 is $\frac{4k}{5}$ kilograms

Solution:

From 1980 to 1990, Lior’s weight increased by 25%

His weight is "k" kilograms in 1990

To find: weight in 1980

This is a percentage increase problem

Let "x" be the weight in kilograms in 1980

The percentage increase is given by formula:

$\text{Percentage increase } = \frac{\text{Final value - initial value}}{\text{initial value}} \times 100$

Here,

Initial value in 1980 = x

Final value in 1990 = k

Percentage increase = 25 %

Substituting the values in formula,

$25 = \frac{k-x}{x} \times 100\\\\25x = 100(k-x)\\\\x = 4(k-x)\\\\x = 4k - 4x\\\\5x = 4k\\\\x = \frac{4k}{5}$

Thus the weight in kilograms in 1980 is $\frac{4k}{5}$
