Answer:

The second and third choices are true

Step-by-step explanation:

In mathematics, a translation is a type of transformation where the object is moved horizontally and/or vertically, but it is not resized, reshaped, or rotated. To create R'T', the segment RT can be moved up, down, left, right, or diagonally. However, the length will be the same.

The first choice is incorrect because R'T' is the same length as RT, so it is definitely not shorter. That being said, the second statement must be correct because the length is the same.

The third choice is also correct. R'T' will be in a different position because it will have been translated, but the orientation will be the same (orientation typically refers to rotation, and the line is not rotated in a translation).

The fourth choice is incorrect because R'T' is not a rotation (so it is not turned). The fifth statement is incorrect because the only ways to switch the positions of R and T would be rotation or reflection (two other types of transformations). Finally, the last choice is incorrect because the line is moved, so there is a position change involved.

Therefore, the second and third choices are true

To find the slope, pick two points on the line, and use the slope formula

( 0,50) and  (30,30)

m = ( y2-y1)/(x2-x1)

   = (30-50)/(30-0)

    = -20/30

Twenty-four minus 5 times a number is fifteen.
tankabanditka [31]

Answer:

Step-by-step explanation:

Let the number be x

5 times a number = 5x

24 - 5x = 15

-5x = 15-24

-5x = -9

x= -9/-5

x = 9/5

x=1\frac{4}{5}

or x = 1.8

Alex is paid $30/hr at full rate, and $20/hr at a reduced rate. The hours of work are paid at a ratio of 2:1, full rate : reduce
Roman55 [17]

Answer:

  $106.67

Step-by-step explanation:

Using the example, for 3 hours work, Alex would be paid ...

  (2 hr)($30/hr) +(1 hr)($20/hr) = $60 +$20 = $80

At the same rate of pay, for 4 hours work, the pay would be ...

  pay/(4 hr) = $80/(3 hr)

  pay = $80(4/3) ≈ $106.67

Alex's pay for 4 hours of work is $106.67.

Answer:

The expression equivalent to 8 - (6r + 2) is -6r + 6 ⇒ A

Step-by-step explanation:

Let us solve the question

∵ The expression is 8 - (6r + 2)

→ Multiply the bracket by (-)

∵ (-) × (+) = (-)

∴ 8 - (6r + 2) = 8 - 6r - 2

→ Add the like terms

∵ 8 - (6r + 2) = (8 - 2) - 6r

∴ 8 - (6r + 2) = 6 - 6r

→ Switch the terms

∴ 8 - (6r + 2) = -6r + 6

∴ The expression equivalent to 8 - (6r + 2) is -6r + 6
