PLEASE ANSWER!!! Brainliest to whoever answers at first!Order the following expressions by their values from least to greatest.

Brilliant_brown [7]

Answer:

-j, 0, j-k

Step-by-step explanation:

j is a positive number, so -j will be less than 0.

j is a number greater than k, so j - k will be greater than 0.

From least to greatest, the order is ...

-j, 0, j-k

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

Without building the graph find the coordinates of the point of intersection of the lines gIven by the equations y=2x+3 and 3x+y

Natali5045456 [20]

Answer:

intersection is (1,5)

Step-by-step explanation:

plug one equations into the other

y=2x+3

3x+y=8

3x+2x+3=8

simplify

5x+3=8

subtract 3

5x=5

x=1

plug x into one equation

y=2+3=5

intersection is (1,5)
