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.

Think about the two rules of similarity to help you answer.
They can never be similar because their __________ can never be ______ and their _______ can never be ___________.
.

Answers

Answer:

They can never be similar because their sides can never be proportional and their angles can never be congruent.

Step-by-step explanation:

Hope It Helps

I did the k12 test!!

They can never be similar because their angles can never be equal and their sides can never be proportional.

What are Similar Triangles?

Two triangles are said to be similar if the triangles are of the same shape but different size. The angles of the triangle will be equal and the sides are proportional.

An equilateral triangle has all the sides and angles equal to each other.

Any similar triangle for an equilateral triangle will have the sides proportional.

Since all the sides are equal, the similar triangle will also have all the sides equal which may be different from the original triangle.

So this can never be similar to a scalene triangle where all the sides are of different length.

Hence the correct reason is that, their angles can never be equal and their sides can never be proportional.

You are running a fuel economy study. One of the cars you find is blue. It can travel 33 1/2 miles on 1 1/4 gallons of gasoline. Another car is red. It can travel 21 3/5 miles on 4/5 gallons of gasoline. What is the unit rate for miles per gallon for each​ car? Which car could travel the greater distance on 1 gallon of​ gasoline?

Answers

Answer:

1) blue car 28.4 miles per gallon

2)  miles per gallon

3) Blue car

Step-by-step explanation:

In order to get the unit rate, we must divide the miles by the gallons so

Blue car: 33.5 / 1.25 = 28.4

Red car: 21.6 / 0.8 = 27

The blue car travels a greater distance on 1 gallon since 28.4 > 27

Answers

Answer: $10

Step-by-step explanation:Let the money spent by each friend = $x

Number of persons including Donovan = 4

Total amount spent by all friends all together = $4x

Since each spent half of their money on rides so amount spent on rides =  = $2x

Then they each spent $3 on food so total money spent = $(2x + 12)

Remaining money = $8

Now the equation will be

$4x - $(2x + 12) = $8

4x - 2x - 12 = 8

2x - 12 = 8

2x = 12 + 8

x = $10

Therefore, each friend spent $10.

Since the price is 49.99$
you’d want to multiply the price by the fraction we just made:

49.99*8.25/100

Answer:4.12

Step-by-step explanation:

49.99 ...... 100%
