Solve the following inequality. 8p + 2 > 3p - 15

The solution is that P > -17/5 or P > -3.4

Step-by-step explanation:

To solve this system, simply isolate P using the order of operations.

8P + 2 > 3P - 15

5P + 2 > -15

5P > -17

P > -17/5

 P > -3 2/5 OR P > -17/5

Step-by-step explanation:

8P + 2 > 3P - 15

5P > -17

P > -3 2/5

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.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
