Answer:

The answer is C

Step-by-step explanation:

It is nonlinear but you have to look at it compared to the months passed. In three months the total houses built are 33 this would mean each month they build 11 houses but in the fourth month they have built 46 houses because 46-11 dosnt equal 33 it is nonlinear.

Answer:  It is nonlinear because the increase in the "Total house built" compared to the "Months Passed" does not show a constant rate of change.

Step-by-step explanation:

We say function to be linear if the rate of change in dependent variable (y) with respect to independent variable (x) is constant.

Rate of change =\dfrac{\text{Change in dependent variable}}{\text{Change in independent variable}}

According to the question ,

Independent variable = Number of months

Dependent variable = Total house built

Now rate of change of "Total house built" for month 0 to 3:-

\dfrac{33-0}{3-0}=\dfrac{33}{3}=11                           (1)

Rate of change of "Total house built"fro month 3 to 4:-

\dfrac{46-33}{4-3}=\dfrac{13}{1}=13                         (2)

From (1) and (2), it is clear that the rate of change is not constant

(∵ 11≠ 13 ).

Hence, the correct answer is : It is nonlinear because the increase in the "Total house built" compared to the "Months Passed" does not show a constant rate of change.

9. Solve for x,<br>9x - 25<br>5x + 7<br>N​
kati45 [8]

Answer:

x = 8

Step-by-step explanation:

Simplifying

9x + -25 = 5x + 7

Reorder the terms:

-25 + 9x = 5x + 7

Reorder the terms:

-25 + 9x = 7 + 5x

Solving

-25 + 9x = 7 + 5x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-5x' to each side of the equation.

-25 + 9x + -5x = 7 + 5x + -5x

Combine like terms: 9x + -5x = 4x

-25 + 4x = 7 + 5x + -5x

Combine like terms: 5x + -5x = 0

-25 + 4x = 7 + 0

-25 + 4x = 7

Add '25' to each side of the equation.

-25 + 25 + 4x = 7 + 25

Combine like terms: -25 + 25 = 0

0 + 4x = 7 + 25

4x = 7 + 25

Combine like terms: 7 + 25 = 32

4x = 32

Divide each side by '4'.

x = 8

Simplifying

x = 8

A number is equal to twice a smaller number plus 3. Yhe same number is equal to twice the sum of smaller number and 1. How many
allsm [11]

Answer:

There is no solution to the problem

Step-by-step explanation:

In order to find the solutions to the problem you can write the situation in an algebraic form.

You have that a number is equal to twice a smaller number plus 3. This can be written as follow:

x=2y+3      (1)

where x is the number and y is the smaller number

Furthermore, the same number x is equal to twice the sum of the smaller number and 1, which can be written as follow:

x=2(y+1)     (2)

To find the solution you equal the equation (1) with (2), and you solve for y:

2y+3=2y+1

3=1

You obtain an inconsistency, hence, the situation of the problem does not have solution
