1. Which situation does NOT represent a functional relationship?
[A] Dave is a construction supervisor for several job sites. When Dave secures a contract for an additional job, he must hire 5 new construction workers to cover that Jobsite. The number of construction workers Dave oversees is related to the number of job sites under Dave's supervision.

[B] Betsy opened an account with $2,500 she had saved from a summer job. During the school year, she withdrew $200 each month from the account. The amount of money in Betsy's account is related to the number of months since Betsy opened the account.

[C] As a zoo veterinarian, Wanda is in charge of ordering vitamins for the spider monkeys. To be healthy, each monkey receives 3 vitamins. The number of vitamins that Wanda must order to have healthy spider monkeys is related to how many sider monkeys are kept at the zoo.

[D] Once a week, Rockwell participates in a soccer exercise. Based on Rockwell's performance, the soccer coach assigns two scores to Rockwell's evaluation form. How well Rockwell did on his performance as indicated by his scores is related to the number of weeks since Rockwell started practicing.

2. Determine A ÷ B, where A = 62x – 100 and B = 2x – 3.

[A] [tex]\frac{1}{31}[/tex]

[B] 60x - 97

[C] 31 - [tex]\frac{7}{2x - 3}[/tex]

[D] [tex]\frac{7}{2x - 3}[/tex]

Recall that y = f(x) since both are outputs of a function

Saying f(x)+5 is the same as y+5. So we're adding 5 to each y coordinate of each (x,y) point. A point like (1,7) turns into (1,12) after doing this shifting.

Doing this to every point shifts the entire f(x) curve 5 units up to get g(x)

Answer:

Part A: 5.5

Part B: Kindly refer to the attached image for the number line representation.

Step-by-step explanation:

Given that:

Possible area of the first garden = 30 sq ft

Possible area of the second garden = 40 sq ft

Possible length of the second garden = 6.3 ft

Possible area of the third garden = 50 sq ft

Possible length of the third garden = 7.1 ft

To find:

Part A: Side length of the square with area 30 sq ft to the nearest tenth.

Part B: Locating and graphing the three points on a horizontal number line.

Solution:

Formula for area of a square:

[tex]Area =(Side)^2[/tex]

Part A: Given that area = 30 sq ft

Putting in the formula to find the value:

[tex]30=Side^2\\\Rightarrow Side = 5.477 \approx \bold{5.5\ ft}[/tex]

Part B:

Kindly refer to the attached image for the number line representation of the given two lengths and the length calculated for the first square.

The three lengths are 5.5, 6.3 and 7.1 respectively.

The three numbers to located on the graph are = 5.5, 6.3 and 7.1

Tony just simplified the equation by 2 (÷2 or ×0.2)

Step-by-step explanation:

Answer:

a,c,d,e

Step-by-step explanation:

The points  A = -0.8, B = -0.2, C = -0.7, D = -0.9, E  = -0.5, F  = -0.25, and G  = -0.4 lie between -1 and 0 on the number line.

An arithmetic value used to indicate an amount is called a number. A number is a mathematical concept that is used for counting, measuring, and labeling. Thus, mathematics is built on numbers.

Given:

A number line going from negative 1 to 0,

the number Point A = -0.8, B = -0.2, C = -7 / 10, D = -9 / 10, E = -1 / 2, F = -1 / 4, and G = -2 / 5

Convert all the points in decimal form as shown below,

C = -7 / 10 = -0.7

D = -9 / 10 = -0.9

E = -1 / 2 = -0.5

F = -1 / 4 = -0.25

G = -2 / 5 = -0.4

As you can see that the numbers lying between -1 and 0,

Thus, all points lie on the number line between -1 and 0.

Answer:

g

Step-by-step explanation:

gg

The value of the function g(7) will be 770.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that the function is g(x) = 175 + 85x. The value of the function at x =7 will be calculated as,

g(x) = 175 + 85x

g(7) = 175 + ( 85 x 7 )

g(7) = 175 + 595

g(7) = 770

Hence, the value of the function will be 770.

Answer: x+1

a number = x + 1

Answer:

yes

Step-by-step explanation:

Answer:

3x–2x+8 = 10x+5

=> x + 8 = 10x + 5

=> 8 – 5 = 10x – x

=> 9x = 3

=> x = 3/9

=> x = 1/3

Pick an x value like x = 2

Note that f(2) = 1 and g(2) = 2. This shows we've doubled the f(x) value to get g(x). Therefore k = 2.

Or you could pick on x = 4 to see f(4) = 2 and g(4) = 4. The output of f(x) has been doubled as well.

It doesn't matter what x is since we'll have this doubling effect go on. I recommend picking x values where the points on the blue graph land perfectly on a grid location. Something like x = 5 seems a bit tricky.

Answer:

The least amount of time both trains will arrive at the starting points at the same time is 36 seconds.

Step-by-step explanation:

From the question, Train A returns to its starting point every 12 seconds and Train B returns to its starting point every 9 seconds.

First, we will determine the times the trains will return to the their starting points.

For Train A,

The second time Train A will return to its starting point will be at 24 seconds,

The third time will be at 36 seconds

The fourth time will be at 48 seconds and so on.

For Train B,

The second time Train B will return to its starting point will be at 18 seconds,

The third time will be at 27 seconds

The forth time will be at 36 seconds and so on.

Since both trains arrive at their starting points at 36 seconds,

Hence, the least amount of time both trains will arrive at the starting points at the same time is 36 seconds.

Answer:

The amount the student needs to save is approximately $269.167

Step-by-step explanation:

The amount the student already has saved for his laptop = $307.50

The amount the student puts aside each month to pay for the laptop = $100

The total amount saved after 5 months = 75% of the total cost of the laptop

Therefore, we have;

The total amount the student has after 5 months = $307.5 + 5 × $100 = $807.5

The total amount saved after 5 months = 75% of the total cost of the laptop

Therefore;

$807.5 = 75% of the total cost of the laptop

The total cost of the laptop = $807.5/75% = $807.5/75 × 100 = [tex]\$ \ 1076\frac{2}{3}[/tex]

The total cost of the laptop ≈ $1076.67

Therefore;

The amount the student needs to save = $1076.67 - $807.5 = [tex]\$ \ 269\frac{1}{6}[/tex]

The amount the student needs to save ≈ $269.167.
