What is the equation of this line? Please help I will give extra points and the brain thing.

y=−3x−4/3

y=4/3x−3

y=3/4x−3

y=−3x−3/4

The equation of this line is y= 3/4x - 3

Because the y intercept is -3 and the slope is rise 3 run 4 making it 3/4. It is a increasing line so it has a positive slope

Because the y intercept is -3 and the slope is rise 3 run 4 making it 3/4. It is a increasing line so it has a positive slope

y=3/4x -3. You find the slope which is rise 3 and run 4 so it’s 3/4. Then the y intercept is already given to you since it’s just where the slope crosses the y axis. Y intercept is -3.

Answer:

Step-by-step explanation:

The common difference, d, is 3, because the number of squares goes up by 3 each time.

d = 3

Number of squares in nth figure is:

a(n) = 4 + d(n - 1)

4 is the initial number of squares, d is how many it goes up each time, and we take n-1 because you need to account for the initial number of squares.

a(n) = 4 + d(n - 1)

For n = 200

a(n) = 4 + d(n - 1)

a(200) = 4 + 3(200-1)

a(200) = 4 + 3(199)

a(200) = 4 + 597

a(200) = 601

△ABC and △CDE similar right triangles. The coordinates of all the vertices are integers.

A. The slope of AC¯¯¯¯¯ is less than the slope of CE¯¯¯¯¯ . This is because the ratio of the change in y-values of the endpoints to the change in x-values of the endpoints is less for AC¯¯¯¯¯ than for CE¯¯¯¯¯ .

B. The slope of AC¯¯¯¯¯ is greater than the slope of CE¯¯¯¯¯ . This is because the ratio of the change in y-values of the endpoints to the change in x-values of the endpoints is greater for AC¯¯¯¯¯ than for CE¯¯¯¯¯ .

C. The slope of AC¯¯¯¯¯ is equal to the slope of CE¯¯¯¯¯ . This this because ratio of the change in y-values of the endpoints to the change in x-values of the endpoints is the same for AC¯¯¯¯¯ as for CE¯¯¯¯¯

D. The relationship between the slope of AC¯¯¯¯¯ and the slope of CE¯¯¯¯¯ cannot be determined, because the triangles are congruent.

**Answer:**

C.) The slopes are equal

**Step-by-step explanation:**

Since both of the triangles are similar right triangles they have the same slope, in order for triangles to be similar, you must be able to make them look the same. In this case triangle, CDE is a down-scaled version of triangle ABC meaning if you just multiplay all the vertices by the same (and correct) number it will make a triangle the same as ABC, therefore the triangles have equal slopes.

C I believe it’s the one that makes more sense

Store 2 has a better deal do u want an explanation

**Step-by-step explanation:**

okay so my explanation is if they both are selling for the same price then look at how many they are selling if store 1 is selling 12 for 3.50 and Store 2 is selling 15 then Store 2 has the better price. Hint if you ever have a problem lie this then you first look at the price if the price is the same then you look at how many they are selling if one of them is selling more than that is the better price

Store 2 :) because it is cheaper.by

A case of 11 dozen place mats costs $23.76. What is the cost for one place mat?

$0.02

$0.18

$0.22

$2.16

**Answer:**

$2.16

**Step-by-step explanation:**

There are 11 mats. The question is asking for the price of 1 mat. You know that 11 mats cost $23.76. You devide $23.76 with the number of mats which is 7 and you get $2.16.

A conversion table indicates that 1 mile is 1.6 km. With this conversion rate, is the speed limit greater than or less than 65 mph? Explain.

greater because 1.6 is larger than 1

**Answer:**

higher than

**Step-by-step explanation:**

The speed limit is 110 km hour and there are 1.6 kilometers in a mile. This means that there are 110 ÷ 1.6 miles per hour:

110 km hour÷1.6 km mile=110÷1.6 miles hour.

**We can find 110 ÷ 1.6 using long division and it is 68.75. So the speed limit is higher than 65 mph**

It is y=2x-6. Anymore questions?

**Answer:**

y=2x-6

**Step-by-step explanation:**

The slope of a line shows the direction of a line. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points.

Juan and Gloria are comparing the two numbers 354.6 and 354.06. Juan says that 354.06 is equal to 10 x 354.6. Gloria says he is wrong. Do you agree with Juan or Gloria? Explain your thinking.

I agree with Gloria because Juan’s answer would be 3546.6. If you multiply any number by 10 it is moving to decimal 1 place to the right so as an example 354.06 multiplied by 10 would be 3540.6 because you moved the decimal to the right one number.

Juan is incorrect; Gloria is right. 354.06 is not equal to 10 times 354.6 as the zero only changes the **decimal** place value.

Gloria is accurate while Juan is mistaken. 354.6 and 354.06 do not add up to the same number. It is not possible to get a value that is 10 times the other number (354.6) by adding a zero to the **decimal point **(354.06).

Only the decimal place value is altered when a zero is added the actual **numerical value **remains unchanged. Compared to 354.6, which only has one decimal place, 354.06's additional zero after the decimal point indicates a more accurate **measurement**. Juan was mistaken when he said that 354.06 was equal to 10 times 354.6.
