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.

The population of Missoula, MT was 67,358 people in 2010. What was the increase if there were 75,516 people in 2019? What was the average increase per year?

Answers

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.

What is Subtraction?

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.

What is the solution to this equation? 4x + 3 = 35
(PLS ANSWER ASAP)

Answers

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

Step-by-step explanation:

4x + 3 = 35

4x = 35-3

pasty needs 3 1/3 cups of flour for a recipe. write the numbers of cups as an inproper fraction
11/3
9/3
10/3
7/3

Answers

Answer:9/3
It’s 9/3 bc all you have yo do it 3x3 then you add the 1 and that equals 9 and then you keep your denominator.
The number of cups as an improper fraction would be 10/3. You can multiply the whole number (3) by the denominator in the fraction (3) to get the number of 1/3 cups in 3 full cups. This would equal 9, or 9/3. And, since you already had a third of a cup in your total, you would add that to the 9/3 cups. So, you would have 1/3 + 9/3 = 10/3 cups

you can then take away 6 from both sides
leaving you with 6x = 15
divide those by 6
leaving you with x = 2.5

you can then check this by doing 2.5 times 6 = 15
