7 0

Answer:

y = -2

Step-by-step explanation:

Step 1: Combine like terms.

  • (y+3y+5y)=-18
  • 9y=-18

Step 2: Divide both sides by 9.

  • 9y/9=-18/9
  • y=-2

Step 3: Check if solution is correct.

  • -2+3(-2)+5(-2)=-18
  • -2-6-10=-18
  • -18=-18

Therefore, y = -2.

Are rectangles ABCD and WXYZ congruent? Why or why not? Yes, all right angles were preserved. Yes, both rectangles have an area
Setler79 [48]

Answer:

D. No, there is not a rigid transformation or a combination of rigid transformations that will map ABCD to WXYZ.

Step-by-step explanation:

Two figures are congruent if their vertices can be mapped into one another by appropriate rigid transformation or combination of rigid transformations. Examples of the transformation are; reflection, dilation, rotation and translation.

Comparing the two figures, it would be observed that they are not congruent. Since there is not a rigid transformation or a combination of rigid transformations that will map ABCD to WXYZ.

Can you step by step solve 20x+12=4x-16
Murljashka [212]

Answer:

x = - \frac{7}{4}

Step-by-step explanation:

Given

20x + 12 = 4x - 16 ( subtract 4x from both sides )

16x + 12 = - 16 ( subtract 12 from both sides )

16x = - 28 ( divide both sides by 16 )

x = \frac{-28}{16} = - \frac{7}{4} [ = - 1.75 ]
