Answer:

y = 4x + 4

Step-by-step explanation:

The equations in the options are all in the slope-intercept form, y = mx + c. In this form, m is the slope while c is the y-intercept.

The slope of a line can be found using the formula below:

[tex]\boxed{\text{Slope}=\frac{y_1-y_2}{x_1-x_2} }[/tex]

In the formula, [tex](x_1, y_1)[/tex] is the first point and [tex](x_2, y_2)[/tex] is the second point on the graph.

Let's identify the two points in the graph which we can use to calculate the slope.

The 2 given points are: (-2 , -4) and (0 , 4)

Substituting the 2 pairs of coordinates into the slope formula:

Slope

[tex]=\displaystyle{\frac{-4-4}{-2-0}}[/tex]

[tex]\displaystyle{=\frac{-8}{-2}}[/tex]

= 4

Substitute the value of the slope into m:

y = 4x + c

The y-intercept, c, is the y value in which the line cuts through the y-axis (vertical axis). It is also the y-coordinate of the point when the x = 0.

In this question, we are given the point (0 , 4) which is also the y-intercept.

Substitute c = 4 into the equation:

y = 4x + 4

Thus, the equation shown in the graph is y = 4x + 4.

Answer:

[tex]\boxed{\sf{x=8}}[/tex]

Step-by-step explanation:

It is necessary to isolate one side of this equation in order to find the solution.

4x+3=35

First, subtract by 3 from both sides.

[tex]\sf{4x+3-3=35-3}[/tex]

Solve.

Subtract.

35-3=32

[tex]\sf{4x=32}[/tex]

Then, divide by 4 from both sides.

[tex]\sf{\dfrac{4x}{4}=\dfrac{32}{4}}[/tex]

Solve.

Divide.

32/4=8

[tex]\Rightarrow \boxed{\sf{x=8}}[/tex]

Therefore, the solution is x=8, which is our answer.

I hope this helps, let me know if you have any questions.

Answer: x = 8

Answer: Using the mean concept, it is found that the average score of Adrian’s favorite team relative to its opponent using the observations Adrian made during the game is of -0.3333.

-----------------

The mean of a data-set is given by the sum of all observations divided by the number of observations.

Adrian looked the scores every 10 minutes in 2 hours, thus 12 times, as .

4 times ahead by 3 points, thus

4 times behind by 4 points, thus

At the other moments, the game was tied, thus the observation is 0.

The average score of Adrian’s favorite team relative to its opponent using the observations Adrian made during the game is of -0.3333.

Step-by-step explanation:

Each value of 10 would equal 7. This would mean that 50 would equal 35 since 7x5=35. This would also mean that 100 would equal 70 since 7x10=70. This would also make sense for the last one since 10÷3=1.4

Answer: 906

Step-by-step explanation:

75,516-67,358= 8,158

2019-2010= 9 years

8,158÷9= 906

The increase in the population is 8158 and average increase in the population per year is 906.4.

Subtraction can be done for any numbers or algebraic expressions. It is the process of taking out certain value from a given amount of number.

The process of subtraction can also be termed as finding difference.

Given that,

Population of Missoula in 2010 = 67,358

Population of Missoula in 2019 = 75,516

Increase in the population = 75,516 - 67,358 = 8158

Average increase in the population per year = 8158 / (2019 - 2010)

                                                                           = 8158 / 9

                                                                           = 906.4

Hence the increase in the population is 8158 and average increase per year is 906.4.
