Liam is setting up folding chairs for a meeting. If he arranges the chairs in 4 rows of the same length, he has 3 chairs left ov
miskamm [114]

Answer:

75 chairs

Step-by-step explanation:

1. 9x+3 : write equation

2. 7x+19 : write equation

3. 9x+3=7x+19 : make both equations equal to each other

4. 2x+3=19 : subtract 7x from both sides

5. 2x=16 : subtract 3 from both sides

6. 8 : divide 2 on both sides of the equal sign

7. 9(8)+3=75 : plug 8 into the equation

s2008m [1.1K]

Answer:

A: You plot these points (-3,4) (-3,6) (-5,6) (-7,4)

B: The transformation would be described as a reflection over the y axis

C:  The transformation does result in a congruent figure because the shape doesn't change in size or shape and in length or width

Step-by-step explanation:

So our plots from the figure are: (3,4)  (3,6)  (5,6)  (7,4)

So using the rule (x, y) → (-x, y) are new points would be:

(-3,4)

(-3,6)

(-5,6)

(-7,4)

This rule (x, y) → (-x, y) is used for the type of transformation that is a reflection but over the y axis.
