Given f(x) = 3/2x - 8, solve for x when f(x)= 7
Answer:
x is 10 when f(x) = 7
Step-by-step explanation:
f(x) is another way of saying y=. The question is basically asking, what is the value of x when the 3/2x - 8 = 7
So, to do this, you are going replace y with it's numerical value. The numerical value given to you is 7. Now, you are going to solve for x (by isolating x).
[tex]7= \frac{3}{2} x-8\\7+8= \frac{3}{2} x-8+8\\15 = \frac{3}{2} x\\15 / \frac{3}{2} = (\frac{3}{2}x) / 3/2\\10=x[/tex]
f(10) = 7
Check your work?
Plug in 10 where you see x.
y = 3/2x - 8
y = (3/2)(10)-8
y = 7 ✅

Anna made a scale drawing, in inches, of a building using a scale of 1:600 . Her scale drawing was 6 inches long. Greg made a scale drawing of the same building using a scale of 1:300 How long, in inches, was Greg's scale drawing?
Answer:
1200 inches
Step-by-step explanation:
Given that:
Scale used by Anna in her drawings = 1 : 600
Length of drawing made by Anna of a building = 6 inches
Scale used by Greg in the drawing = 1 : 300
To find:
The length of scale drawing made by Greg.
Solution:
Here, we first need to find the original length of the building so that we can find the length of scale drawing made by Greg.
Ratio 1 : 600 means 600 is the actual length of building, if the length of scale drawing is 1.
Here, we are given length of scale drawing as 6 inches, therefore the actual length of building = 6 [tex]\times[/tex] 600 = 3600 inches
Now, applying the ratio 1 : 300, we get the length of scale drawing by Greg as [tex]\frac{3600}{3}[/tex] = 1200 inches

there are 84 calories in 100g of banana there are 87 calories in 100g of yoghurt priti has 60 g of banana and 150g of yoghurt for breakfast work out the total number of calories in this breakfast
Total calories intake of Priti is 180.9 calories
Given that;
Number of calories in 100g banana = 84 calories
Number of calories in 100g yoghurt = 87 calories
Amount of banana and yoghurt Priti have = 60g and 150g respective
Find:
Total calories intake of Priti
Computation:
Total calories intake of Priti = 60[84/100] + 150[87/100]
Total calories intake of Priti = 50.4 + 130.5
Total calories intake of Priti = 180.9 calories

The probability that Amy will reach in the jewelry box and pull out a necklace that is not silver is 3/20 and this can be determined by using the given data.
Given :
Amy has 20 necklaces in a jewelry box. The probability of reaching into the jewelry box and pulling out a silver necklace is 0.85.The following steps can be used in order to determine the probability that Amy will reach in the jewelry box and pull out a necklace that is not silver:
Step 1 - According to the given data, the probability of reaching into the jewelry box and pulling out a silver necklace is 0.85.
Step 2 - The overall probability is 1.
Step 3 - So, the probability that Amy will reach in the jewelry box and pull out a necklace that is not silver is calculated as:
P = 1 - 0.85
P = 0.15
P = 3/20
Therefore, the correct option is C).

Part 1
You will need to measure five different people. Record your measurements on a piece of paper. Using a tape measure or ruler, measure the length (in inches) of a person’s left foot and then measure the length (in inches) of that same person’s forearm (between their wrist and elbow). Refer to the diagrams below. You will have two measurements for each person.
(An easy way to measure the length of a foot is to have your subject stand on a piece of paper. Then, trace their foot and measure the outline once they move off the paper.)
To measure the forearm, measure inside the arm, between the wrist and the elbow.
Part 2
Organize your data and find the rate of change.
Create a table of the measurements for your data. Label the forearm measurements as your input and the foot measurements as your output.
Select two sets of points and find the rate of change for your data.
Describe your results. If you had to express this relation as a verbal statement, how would you describe it?
Part 3
Compare rates of change.
The equation below can be used to find the length of a foot or forearm when you know one or the other.
(length of the foot) = 0.860 • (length of the forearm) + 3.302
If you let y = length of the foot and x = length of the forearm, this equation can be simplified to
y = 0.860x + 3.302.
Using this equation, how long would the foot of a person be if his forearm was 17 inches long?
What is the rate of change of the equation from Part A?
Compare the equation from Part A to your data. Are they the same? Which has a greater rate of change? Why do you think the values are different?
Is the relation in your data a function? Why or why not? Could the equation in Part A represent a function? Why or why not? Explain your answer.
For this option you will submit the details from all three parts. Submit your measurements, the table, and description that you created in Parts 1 and 2. Submit your answers to the questions from Part 3.
Answer:
again please don't just straight up copy it just use it as a base please also i tried my best and don't know if i got it right
Step-by-step explanation:
Part 2
Organize your data and find the rate of change.
I’m sorry i didn’t know how to make a table so i just did this
Person number 1- Left foot is 9 inches Forearm is 8.5 inches
Person number 2- Left foot is 7.5 inches Forearm is 7 inches
Person number 3- Left foot is 11 inches Forearm is 10.5 inches
Person number 4- Left foot: is 10 inches Forearm is 9.5 inches
Person number 5- Left foot is 6 inches Forearm is 5.5 inches
The rate of change equals y=x-0.5
I believe that it's a function because there is a relationship between 2 variables.
Part 3
Compare rates of change.
The equation below can be used to find the length of a foot or forearm when you know one or the other.
(length of the foot) = 0.860 • (length of the forearm) + 3.302
If you let y = length of the foot and x = length of the forearm, this equation can be simplified to
y = 0.860x + 3.302.
Using this equation, how long would the foot of a person be if his forearm was 17 inches long?
i don’t know how to type all my formulas and work so i'm just going to say the answer i got the rate of change = 0.86x or y=0.86x+3.302
What is the rate of change of the equation from Part A?
For Part A i got y=x-0.5 and that part A has the greater rate of change.
Compare the equation from Part A to your data. Are they the same? Which has a greater rate of change? Why do you think the values are different?
Well, the values have to be different because there are different rates of change and different linear coefficients; and also each input value will result in a different output value because they all have different parameters as well.
Is the relation in your data a function? Why or why not? Could the equation in Part A represent a function? Why or why not? Explain your answer.
Yes, it is a function because each input from part A fits well together with the output on the other set, which matches the definition of a function.

Answer:
C
Step-by-step explanation:
The equatipn of the function that represents the same relationship is
h(x)=-3x-10.5
Equation of a line :The slope intercept form of equation of line is y=mx+b
where m is the slope and b is the y intercept .
We are given with a table that represents the linear function
Pick any two points from the table to find out slope
(-3.5,0) and (-1,-7.5)
[tex]slope =\frac{y_2-y_1}{x_2-x_1} =\frac{-7.5-0}{-1+3.5}=-3[/tex]
Now we find out y intercept b . use point slope form
