Phillp charges $8 the first time he walks a dog and $2 per walk after that. Carrie charge $2 the first time he walks a dog and $3 per walk after that. Write the system of equations

8 + 2 * X = P

2 + 3 * X = C

Step-by-step explanation:

By means of the statement we have to:

Phillp case: "Charges $ 8 the first time he walks a dog and $ 2 per walk after that" that is:

P = 8 + 2 * X

Where X would be the number of walks.

Carrie case: "Charge $ 2 the first time he walks a dog and $ 3 per walk after that" That is:

C = 2 + 3 * X

Where X would be the number of walks.

Therefore the equation system would be:

8 + 2 * X = P

2 + 3 * X = C

P and C earnings of Phillp and Carrie respectively.

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
