Answer:

UT = 8

Step-by-step explanation:

From the picture, we can make the following equation...

5 + 2x - 6 = x + 6

By solving it we get

5 + 2x - 6 = x + 6

2x - 1 = x + 6

2x = x + 7

x = 7

Therefor if UT = 2x - 6, then UT is equal to...

2x - 6 = UT

2(7) - 6 = UT

14 - 6 = UT

8 = UT

Answers

Answer:

x=-10, y=-20

Step-by-step explanation:

first you substiture the y in the second equation with the first

x-2x=10

then solve

1x-2x=-1

-x=10

multiply both sides by a negative to make the varible a

positive

x=-10

now we substitue the x in the first equation with -10

y=2(-10)

y=-20

A window in the room has an actual width of 4.5 feet. Find the width of the window in the blueprint.
The width of the window in the blueprint is
in.

Answers

Answer:

54 feets

2.5 inches

Step-by-step explanation:

Given that:

Scale model:

5 in : 9ft

If 5 in = 9 ft

Hence, 1 in on the blue print equals

5 in = 9 ft

1 in = x

Cross multiply

5x = 9

x = 9/5 feets

Hence, 1 inches on the blueprint equals 9/5 feets actual

Blueprint length (in.) ___ Actual length (ft)

5 _________ 9

10 ________ 18

15 ________ 27

20 _______ 36

25 _______ 45

30 _______ 54

Hence ;

5 * 9/5 = 9 feets

10 * 9/5 = 18 feets

15 * 9/5 = 27 feets

20 * 9/5 = 36 feets

25 * 9/5 = 45 feets

30 * 9/5 = 54 feets

Window with actual width of 4.5 feets

Width of window in blue print :

Actual width ÷ 9/5

Actual width = 4.5 = 4 1/2 = 9/2

9/2 * 5 /9

= 5 /2

= 2 1/2 inches = 2.5 inches

Answer:

The graph is not a function.

Step-by-step explanation:

Using the "vertical line test" to attach a vertical line to each of the points on the graph, we will find that the vertical line that passes through (0,0) has ot one, but two points on it. Remember, if the vertical line passes through more than one points, the graph is not a function. As we know, the vertical line passes through two points, those being (0, -4) and (0, -3). So, we can conclude that the graph is not a function.
