Step-by-step explanation:

To reflect over the y-axis you change the value of x. In this case all of the values for x are negative. You turn them all into a positive.:

A' (5, 3)

B' (2, 3)

C' (2, 1)

D' (5, 1)

To dialate by a scale factor of 2 you multiple everything by 2 and you should get: A"(10, 6)

What is the value of _a_ in the equation below?

2a + 3 = 4a + 5

Answers

Step-by-step explanation:

hope it is helpful to you

Step-by-step

Simplifying 2a + 3 = 4a + 5

Reorder the terms: 3 + 2a = 4a + 5

Reorder the terms: 3 + 2a = 5 + 4a

Solving 3 + 2a = 5 + 4a

Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right.

Add '-4a' to each side of the equation. 3 + 2a + -4a = 5 + 4a + -4a

Combine like terms: 2a + -4a = -2a 3 + -2a = 5 + 4a + -4a Combine like terms: 4a + -4a = 0 3 + -2a = 5 + 0 3 + -2a = 5 Add '-3' to each side of the equation. 3 + -3 + -2a = 5 + -3 Combine like terms: 3 + -3 = 0 0 + -2a = 5 + -3 -2a = 5 + -3 Combine like terms: 5 + -3 = 2 -2a = 2 Divide each side by '-2'. a = -1 Simplifying a = -1

It is given that

The letter will be 42 cm tall and 33 cm wide.

Each bar of the letter will have a thickness of 8 cm.

The letter H will be made from three rectangular bar

The standing rectangular bar have dimensions of 42 cm * 8 cm

The horizontal rectangular bar will have

Length = 33 - 8 - 8 = 17 cm

Width = 8 cm

Therefore the amount of duct tape required will be equal to the area of the rectangle

Area of the rectangle = 42 * 8 + 42 * 8 + 17 * 8

Area of the rectangle = 808 sq.cm

Area of the duct tape required = 808 sq.cm.

10. Which equation below is equivalent to 3x + 2y = -2?
a. y = -2/3x – 5
b. y = 3/2x + 7
c. y = -3/2x - 1 d. y = 2/3x + 4
e. NOthing

Answers

Answer c, you have to put the equation in slope intercept form which is y=Mx+b so you would subtract the 3x and move it to the other side of the equal sign before the -2 so it would be 2y=-3x-2 then you would divide the 2 on both sides to separate the 2 from the y. -3x/2 is -3/2x 2/-2 is -1 so you answer would be C y= -3/2x - 1 Hope this makes since!
