Three consecutive integers are n, n, +1 and n+2. 4 times the sum of the least and greatest integers is 12 less than three times
raketka [301]

Answer:

The smallest integer is -4.

Step-by-step explanation:

4(n + n+2) = 3*n - 12                          Combine the left

4(2n + 2) = 3n- 12                              Remove the brackets

8n + 8 = 3n - 12                                 Subtract 3n from both sides

8n-3n + 8 = 3n-3n - 12                      Combine

5n + 8 = - 12                                      Subtract 8 from both sides

5n = - 12 - 8

5n = - 20                                           Divide by 5

5n/5 = -20/5    

n = - 4

n + 1 = -3

n + 2 = - 2

The Wheel Shop sells other kinds of vehicles. There are bicycles and go-carts in a different room of the shop. Each bicycle has
Alisiya [41]

Answer:

15 bikes, 6 gocarts

Step-by-step explanation:

so both the vehicles have 1 seat each

the bicycles will be represented by B

the gocarts will be represented by G

because there are only 1 seat per for a total of 21 seats, we have this as the first equation:

B + G = 21

Gocarts have wheels and bikes have 2 seats, so we have this equation:

2B + 4G = 54

from there we can simply replace b with g to find the amount of gocarts first:

B + G = 21

B = 21 - G

2(21-G) + 4G = 54

42 - 2G + 4G = 54

2G + 42 = 54

2G = 12

G = 6

So there are 6 gocarts.

plug in 6 for g

B + 6 = 21

B = 15

therefore, there are 15 bikes and 6 gocarts

Point A (12, 4) is the image of point A(3, 1) under a dilation with respect to the origin. What is the constant of dilation?​
nordsb [41]

Answer:

We conclude that the constant of dilation is: 4

Step-by-step explanation:

We know that when an object is dilated by a scale factor, it gets reduced, stretched, or remains the same, depending upon the value of the scale factor.

  • If the scale factor > 1, the image is enlarged
  • If the scale factor is between 0 and 1, it gets shrunk
  • If the scale factor = 1, the object and the image are congruent

The coordinates of the image point can be determined by multiplying the coordinates of the original point by a certain scale factor.

Given the point A'(12, 4) is the image of A(3, 1).

It is clear that the image point A'(12, 4) is enlarged 4 times of the original point A(3, 1).

It means the image point A'(12, 4) is determined when the original point A(3, 1) is dilated by a scale factor of 4.

i.e.

A(3, 1) → A'(4(3), 4(1)) → A' (12, 4)

Therefore, the rule of dilation by a scale factor 4 is:

P(x, y) → P'(4x, 4y)

Hence, we conclude that the constant of dilation is: 4

Select the correct answer. The graph of function f is shown. An exponential function with vertex at (1, 3) and passes through (m
Crank

The statement which correctly compares the two functions is that: A. they have the same y-intercept and the same end behavior as x approaches ∞.

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

A function is a mathematical expression which can be used to define and show the relationship that exist between two or more variables in a data set.

By critically observing the graph which models the function f (see attachment), we can logically deduce that the y-intercept is at four (4).

Also, from the table of function g (see attachment), we have:

At x = 0, g(x) = g(0) = 4.

In conclusion, the statement which correctly compares the two functions is that they have the same y-intercept and the same end behavior as x approaches infinity (∞).
