Mr. Dexter sells subscriptions to a magazine for $18 each. For each subscription he sells, he earns $8. One month, he sold $900

TiliK225 [7]

Answer:

$400

Step-by-step explanation:

Dexter's earnings can be found using the proportion ...

earnings/sales = $8/$18 = ??/$900

Multiplying by $900, we find ...

?? = $900(8/18) = $400

Dexter's earned $400 on the sales for the month.

Find (f∘g)(x). f(x)=5x+1 g(x)=2x Write your answer as a polynomial in simplest form.

vladimir2022 [97]

(f o g)=f(g(x))
just sub
f(g(x))
sub g(x) for x in f(x)
g(x)=2x
2x=x in f(x)
f(g(x)=f(2x)=5(2x)+1=10x+1

(f o g)=10x+1

Consider the two functions below. Which one of these functions is linear? What is its equation? Enter any answers to two decimal

Sloan [31]

Answer:

$y = 1.67x$

Step-by-step explanation:

Function A:

x || 3 || 6 || 9 || 12 || 15

y || 5 || 10 || 15 || 20 || 25

See attachment for Function B

First, we need to determine the equation of function A using linear interpolation

As follows:

$y = y_1 + (x - x_1)\frac{y_2 - y_1}{x_2 - x_1}$

Take any two corresponding values of x and y to be:

$(x_1,y_1) = (3,5)$

$(x_2,y_2) = (15,25)$

The equation becomes:

$y = y_1 + (x - x_1)\frac{y_2 - y_1}{x_2 - x_1}$

$y = 5 + (x - 3)\frac{25 - 5}{15 - 3}$

$y = 5 + (x - 3)\frac{20}{12}$

$y = 5 + (x - 3)\frac{5}{3}$

Open bracket

$y = 5 + \frac{5x}{3} - \frac{5*3}{3}$

$y = 5 + \frac{5x}{3} - 5$

Collect Like Terms

$y = \frac{5x}{3} - 5 + 5$

$y = \frac{5x}{3}$

$y = 1.67x$

This function is linear and there is no need to check for function B
