butalik [34]

write the above equation in the form of y = g(x).

⇒ y = (0.5)x + 3 – 4

Now, we convert the equation into y = mx + c form.

⇒ y = (0.5)x - 1

Here, we see that m = slope = 0.5, and c = y-intercept = -1.


Hence, the graph of g(x) = (0.5)x + 3 – 4 is a straight line with slope = 1/2 and y-intercept = -1.

Missing details

Which type of function model would be appropriate for this situation?

Answer:

Linear function

Step-by-step explanation:

Given

y = 0.50x +9.75

Required

The function model

A function of the form:

y = mx + b

is referred to as a linear function where

m = slope/rate

b=y\ intercept

By comparison:

m = 0.50\ b = 9.75

<em>So, it is a linear function (linear model)</em>

Bonnie had 1 one-dollar bill, 2 five-dollar bills, and 2 ten-dollar bills in her pocket. She randomly took 3 bills from her pock
Burka [1]

Answer:

There are 5 different outcomes, $30, $21, $20, $16 and $11.

Step-by-step explanation:

Bonnie has a total of 6 bills in her pocket. If she takes 3 random bills, this means that there are 20 different possibilities but the five dollar bills and ten dollar bills are not indistinctive so the number is not 20 for this example.

She can take the 1 dollar bill and the two 5 dollar bills which would make 11 dollars.

She can take the 1 dollar bill and the two 10 dollar bills which would make 21 dollars.

She can take the 1 dollar bill, one 5 dollar bill and one 10 dollar bills which would make 16 dollars.

She can take two 5 dollar bills and one 10 dollar bill which would make 20 dollars.

She can take two 10 dollar bills and one 5 dollar bill which would make 30 dollars.

So there are 5 different outcomes, $30, $21, $20, $16 and $11.

I hope this answer helps.
