Answer:

u = 150

Step-by-step explanation:

Number of vertices:

Find the sum of the interior angles:

180(n - 2)

180(10 - 2)

180(8)

1440

To find u:

u = 1440 - (130 + 145 + 160 + 150 + 130 + 150 + 125 + 155 + 145)

u = 1440 - (1290)

u = 150

You can work at most 20 hours next week. You need to earn at least $90 to cover your weekly expenses. Your dog walking job pays

Vadim26 [7]

Answer:

The answer in the procedure

Step-by-step explanation:

Let

x ----> the dog walking hours

y ----> the car washing hours

we know that

The system of linear inequalities is equal to

$x+y\leq20$ -----> inequality A

$9x+10y\geq 90$ -----> inequality B

Solve the system of inequalities by graphing

The solution is the shaded area

see the attached figure

Two possible combinations of hours are

(10,10) and (0,9)

Verify

For (10,10)

Substitute the value of x and the value of y in both inequalities

Inequality A

$10+10\leq20$

$20\leq20$ -----> is true

Inequality B

$9(10)+10(10)\geq 90$

$190\geq 90$ ----> is true

therefore

(10,10) is a possible solution

For (0.9)

Substitute the value of x and the value of y in both inequalities

Inequality A

$0+9\leq20$

$9\leq20$ -----> is true

Inequality B

$9(0)+10(9)\geq 90$

$90\geq 90$ ----> is true

therefore

(0,9) is a possible solution

PLEASE HELP WILL GIVE BRAINIEST AND A THANKS!!!!! Write the equation of the line.

solong [7]

1.) y= 2/3x
2.)y= -1x + 1
3.)y= 2x + 1
4.)y= -2/3x + 1
The structure of the formula is y = mx + b.
m is the slope.
slope is found by rise over run.
b is the y intercept.
which is found by where the line is on the y axis
