Two  parallel lines are intersect by the same line, and the angles shown lie on the same orientation about the intersection so the angles are equal to each other...which means:

9x+21=10x+10  subtract 21 from both sides

9x=10x-11  subtract 10x from both sides

-x=-11 divide both sides by -1

x=11

Graph y = | x | + 5 .
vovikov84 [41]
I cannot see the images, but... 

y = | x | + 5 

consider the absolute value function. You know that for every value of x, y will be greater than or equal to 5.  this means that the y-intercept will also be the bottom of the curve. 

Plug a few values in for an idea of what the graph will look like: 
f(-1) = 6    (-1,6)
f(1) = 6     (1, 6)
f(-2) = 7    (-2, 7)
f(2) = 7     (2, 7)

The graph will have a minimum value at (0,5), where two lines will converge. The graph will look like a pointy cone with its point at (0,5), with two lines pointing outward and upward from this point. Confirm that the graph passes through the coordinates provided above!

Janet measured a shopping center and made a scale drawing. The scale she used was 1 inch : 6 feet. A bakery in the shopping cent
VikaD [51]

Answer:

The length of the actual bakery is 936 inches or 78 feet

Step-by-step explanation:

From the question we are told:

Janet measured a shopping center and made a scale drawing. The scale she used was 1 inch : 6 feet.

Let both the measurement of the shopping center and scale drawing be written in feet

1 foot = 12 inches

6 foot = x

Cross Multiply

x = 6 × 12 inches

x = 72 inches

Hence, the scale drawing =

Scale drawing : shopping center

1 inch = 72 inches

A bakery in the shopping center is 13 inches in the drawing. How long is the actual bakery?

This is calculated as:

1 inch = 72 inches

13 inches = x inches

Cross Multiply

x = 13 × 72 inches

x = 936 inches

The length of the shopping center = 936 inches

We convert back to feet

= 12 inches = 1foot

936 inches = x

Cross Multiply

12x = 936 × 1

x = 936/12

x = 78 feet

Therefore the length of the actual bakery is 936 inches or 78 feet
