Answer:
(I attached an image of the graphed lines)
Step-by-step explanation:
First, we need to graph the original function:
The given equation is written in y=mx+b form, in which m is the slope and b is the y-intercept, or where the line crosses through the y axis. This means the slope is [tex]\frac{2}{1}[/tex] and the y-intercept is -4.Next, we need to find the inverse of the function and graph that as well:
First, change f(x) in the given equation to y. These mean the same thing, it just makes it easier to work with.Swap the places of x and y. Then, the rest of the steps are essentially just isolating the variable y.Add 4 to both sides of the equation to cancel out the -4 (You will end up with -2y = x + 4)Divide both sides of the equation by -2 to isolate y (You will end up with y = (x/2) + 2)Part A
What is the explicit formula the sequence 8,10,12.5,15.625...?
Given:
The sequence is 8, 10, 12.5, 15.625,...
To find:
The explicit formula for the given sequence.
Solution:
We have,
8, 10, 12.5, 15.625,...
Here, the first terms is 8.
[tex]\dfrac{10}{8}=1.25[/tex]
[tex]\dfrac{12.5}{10}=1.25[/tex]
[tex]\dfrac{15.625}{12.5}=1.25[/tex]
The common ratio is 1.25. So, the given sequence is a geometric sequence.
The explicit formula for a geometric sequence is:
[tex]a_n=ar^{n-1}[/tex]
Where, a is the first term and r is the common ratio.
The explicit formula for the given geometric sequence is:
[tex]a_n=8(1.25)^{n-1}[/tex]
Therefore, the correct option is A.
Anthony makes candies for his party guests. First, he mixes 1 cup of cream with 2 cups of chocolate. In all, he uses 9 cups of these two ingredients. How many cups of chocolate does he use in this candy recipe?
Answer:
Cream = 3 cups
Chocolate = 6 cups
Step-by-step explanation:
Cream = 1 cup
Chocolate = 2 cups
Total = 3 cups
Cream : chocolate = 1 : 2
He uses 9 cups of these two ingredients. How many cups of chocolate does he use in this candy recipe?
Cream = ratio of cream/total ratio of total cups
= 1/3 of 9
= 1/3 × 9
= 3 cups
Cream = 3 cups
Chocolate = ratio of chocolate/total ratio of total cups
= 2/3 of 9
= 2/3 × 9
= 6 cups
Chocolate = 6 cups

13. What is the y-intercept of the line that passes through (4, 1) and has a slope of
-2?
Answer:
The y-intercept of the line is 9.
Step-by-step explanation:
y-y1=m(x-x1)
y-1=-2(x-4)
y-1=-2x+8
y=-2x+8+1
y=-2x+9
y=mx+b where m=slope and b=y-intercept

Ou are a manager at Jimmy John's and have timed how fast your employees make a sandwich. Their times in seconds are below. Create a histogramto represent the data. 21,22.4,23,24.8,25.3,27,27.6,28.8,29.4,29.9,30.1,30.1,30.4,31.2,32,32.9
Answer:
See attachment for histogram
Step-by-step explanation:
Given
[tex]Data: 21,22.4,23,24.8,25.3,27,27.6,28.8,29.4,29.9,30.1,30.1,30.4,31.2,32,32.9[/tex]
Required
Represent on histogram
Calculate the range of the data
[tex]Range = 32.9 - 21[/tex]
[tex]Range = 11.9[/tex]
Using a width of 5, we have:
[tex]Class = \frac{Range}{5}[/tex]
[tex]Class = \frac{11.9}{5}[/tex]
[tex]Class =2.38[/tex]
Round up
[tex]Class = 3[/tex]
This means that the class will have 3 classes which are:
21.0 - 24.9, 25.0 - 29.9 and 30.0 - 34.9
The frequency table is as follows:
[tex]\begin{array}{cc}{Interval} & {Frequency}&{21.0 - 24.9} & {4} & {25.0 - 29.9} & {6} & {30.0 - 34.9} & {6} \ \end{array}[/tex]

Edith rides in an Oober that charges a flat rate of $6.75 plus $3.20 per mile. If the ride share service charges $40.03 in total for her trip, how many miles is her ride? Enter your NUMERICAL answer only in the box as a decimal to the nearest tenth of a mile.
Answer:
10.4 miles
Step-by-step explanation:
c(m) = trip cost
c(m) = 6.75 + 3.2m
40.03 = 6.75 = 3.2m
33.28 = 3.2m
m = 10.4
