Which statement is true about figures ABCD and A′B′C′D′? (1 point)

Mathematics

Answer:

Step-by-step explanation:

A'B'C'D' is obtained by rotating ABCD 180° counterclockwise about the origin and then reflecting it across the x-axis.

A(2, -2) is mapped to A'(-2, -2)

B(1, -4) is mapped to B'(-1, -4)

C(0, -2) is mapped to C'(0, -2)

D(1, -1) is mapped to D'(-1, -1)

If we rotate counterclockwise 180°, every point (x, y) is mapped to (-x, -y):

A(2, -2) gets mapped to (-2, 2)

B(1, -4) gets mapped to (-1, 4)

C(0, -2) gets mapped to (0, 2)

D(1, -1) gets mapped to (-1, 1)

Reflecting these images across the x-axis will then map (x, y) to (x, -y):

(-2, 2) gets mapped to (-2, -2)

(-1, 4) gets mapped to (-1, -4)

(0, 2) gets mapped to (0, -2)

(-1, 1) gets mapped to (-1, -1)

These new coordinates are the same as A'B'C'D'.

Susan paid $240 to have her house decorated. The materials used to decorate the house coast $115, and service was charged at $5
Nataly [62]

Answer:

240 =5x +115

And we can solve for x in order to find the number hours using to decorate the house.

We can subtract in both sides 115 and we got:

240-115= 5x

125 = 5x

And now we can divide both sides by 5 and we got:

x= 25

So then the number of hours spent to decorate the house are 25

Step-by-step explanation:

Based on the information given we can model this function with this formula:

y = mx+b

Where y represent the total cost paid, m the cost per hour representing the slope and x the number of hours worked and finally b the initial cost for the materials. Then our function is given by:

240 =5x +115

And we can solve for x in order to find the number hours using to decorate the house.

We can subtract in both sides 115 and we got:

240-115= 5x

125 = 5x

And now we can divide both sides by 5 and we got:

x= 25

So then the number of hours spent to decorate the house are 25

Solve this using Substitution. <br> {y=x+1 <br> {2x+y=7
Elina [12.6K]
Y = x + 1....so we sub in x + 1 for y in the other equation

2x + y = 7
2x + x + 1 = 7 ....combine like terms
3x + 1 = 7....subtract 1 from both sides
3x = 7 - 1
3x = 6 ....divide both sides by 3
x = 6/3
x = 2

y = x + 1
y = 2 + 1
y = 3

so ur solution is : (2,3)

evablogger [386]

Answer:

-20

Step-by-step explanation:

-8v-9=7

Add 9 to each side

-8v-9+9=7+9

-8v = 16

Divide by -8

-8v /-8 = 16/-8

v = -2

Now find

7v -6

7(-2) -6

-14 -6

-20
