Answer:

Kendra should have multiplied the x-values by 75 to get the y-values

Step-by-step explanation:

Given

Table

X|| Y

1 || 75

2 || 150

3 || 225

4 || 300

5 || 375

Given that Kendra multiply x by 7.5 to get y

The relationship of x and y can be calculated as thus;

y = rx

Where y and x are the values at the y and x column respectively and r is the constant of proportionality

When y = 75, x = 1.

Plug in these values in the above formula

y = rx becomes

75 = r * 1

75 = r

r = 75

When y = 150, x = 2

150 = r * 2

Multiply both sides by ½

150 * ½ = r * 2 * ½

75 = r

r = 75

When y = 225, x = 3

225 = r * 3

Multiply both sides by ⅓

225 * ⅓ = r * 3 * ⅓

75 = r

r = 75

Notice that r remains 75 and the difference between y values is 75

If you apply these formula on when y = 300 or 375 and when x = 4 or 5, the constant of proportionality will remain The value of 75.

Hence, Kendra mistake is that; Kendra should have multiplied the x-values by 75 to get the y-values

natta225 [31]

Answer:

1.5kg

Step-by-step explanation:

The mean for the packages on day 1 will be:

= (1 + 8 + 1 + 12 + 1 + 11 + 7 + 6)/8

= 47/8

= 5.875

The mean for day 2 will be:

= (47 + 12)/8

= 59/8

= 7.375

The increase in mean:

= 7.375 - 5.875

= 1.5

What is the effect on the graph of f(2) g(2) =} - 1? 1 when it is transformed to g(x)=1/x -7
777dan777 [17]

The effect on the graph of f(x)= 1/x when it is transformed to g(x)= 1/x-7 is C. The graph of f(x) is shifted 7 units down.

<h3>What is a graph?</h3>

A graph is a diagram showing the relation between variable quantities, each measured along with one of a pair of axes at right angles.

In this case, the effect on the graph of f(x)= 1/x when it is transformed to g(x)= 1/x-7 is that the graph of f(x) is shifted 7 units down.

The missing options include:

A. The graph of f(x) is shifted 7 units up

B. The graph of f(x) is shifted 7 units to the left

C. The graph of f(x) is shifted 7 units down

D. The graph of f(x) is shifted 7 units to the right.

11Alexandr11 [23.1K]

Answer:

-8n + 9

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Distributive Property

<u>Algebra I</u>

  • Combining Like Terms

Step-by-step explanation:

<u>Step 1: Define</u>

A = -3n + 2

B = 5n - 7

A - B

<u>Step 2: Simplify</u>

  1. Substitute:                              -3n + 2 - (5n - 7)
  2. Distribute negative:               -3n + 2 - 5n + 7
  3. Combine like terms (n):         -8n + 2 + 7
  4. Combine like terms (Z):         -8n + 9

otez555 [7]

Answer:

4353.5

Step-by-step explanation:

2 bedrooms and a living room, sorry I forgot to add that in, there's also 3 small windows and a large one

3 rooms

552*3 = 1656

small window = 539.50 * 3 = 1618.50

Large window - 2*539.50 = 1079

1656+1618.5+1079=4353.5
