I need help pls , I’m struggling

Answers

Answer 1

Answer:

Option A is correct.

Step-by-step explanation:

When rotating a point 90 degrees counterclockwise about the origin our point A(x,y) becomes A'(-y,x). In other words, switch x and y and make y negative. Here x=4 and y=6 so on 90° rotation new co-ordinates of B are (-6,4).

Hope it helps you.

One rectangle measures 2 units by 7 units. A second rectangle measures 11 units by 37 units. Are these two figures scaled versions of each other? If so, find the scale factor.

Answers

Answer:

No.

Step-by-step explanation:

If they are scaled versions of each other then the ratio of corresponding sides would be equal.

11/2 = 5.5

37/7 = 5.29

Answers

Answer:

There are 20 potatoes in each bag.

Step-by-step explanation:

There are 12 in a dozen. 10 dozens equal 120.

20 potatoes in each bag.

Hope this helped!

Answer:

there are 20 potatoes in each bag.

Step-by-step explanation:

One dozen is equal to 12, so you have to multiply 12 by 10 to find the number of potatoes Julio's dad bought.

12 x 10 = 120

after finding the number of potatoes bought, you have to divide the number of potatoes by the number of bags:

120 : 6 = 20

Rectangle BCDE is shown on the coordinate grid. Rectangle BCDE is dilated with the origin as the center of a dilation using the rule (x,y) → (1/3x, 1/3y) to create rectangle B'C'D'E
I REALLY NEED HELP!! THANKS

Answers

Answer:

Step-by-step explanation:

Answer: Choice A) Rectangle B'C'D'E' is larger because scale factor is greater than 1.

Going from (x,y) to (3x,3y) means we multiply each coordinate by 3. This is the scale factor. The scale factor being larger than 1 means the new image is an enlargement compared to the original preimage. Specifically the dimensions of the new rectangle are 3 times larger.

Which of the following equations would be solved for x by adding 8 to both sides and then multiplying both sides by 2?

Answers

Answer: A

Step-by-step explanation:

The equation option 3rd is correct option.

What is an equation?

An expression or a statement that comprises two algebraic expressions with the same value and are separated by an equal symbol in between them.

Given that, four equation,

5 = 3x/2 - 8

Adding 8 to both sides,

5 + 8 = 3x/2 - 8 + 8

13 = 3x/2

Multiplying by 2 to both sides,

13*2 = 3x/2*2

26 = 3x

x = 26/3

Hence, equation 3rd is the correct answer.

the sum of the speeds of two trains is 716.7 miles per hour if the speed of the first train is 5.3 miles per hour faster than a second train find the speed of each

Answers

The best way to solve this is to make an algebraic expression to represent the situation~
If x is the speed of the first train and y is the speed of the second we can make 716.7 = x + y
the first train is 5.3 mph faster so x = y + 5.3
Now we can replace x with our new value to get 716.7 = y + (y+5.3)
Simplify and we get 716.7 = 2y + 5.3
Now all we got to do is simplify this equation, 716.7 - 5.3 = 711.4. Divide by 2 to get 355.7 for the speed of the second train. Since the first train is 5.3 mph faster, we add that to the second trains value and get our answer. The first train is going at 361.7, the second at 355.7
