Answer:
A
Step-by-step explanation:
It goes up and down due to the x^3 then the 3x^2
-3x-12> 8x + 21
+12 +12
-3x > 8x + 33
-8x -8x
-11x > 33
————-
-11
x < -3
I moved the real numbers to one side and and the variable to the other side to solve for the inequality
I also remembered somewhere that if you divide by a negative number the inequality sign switches.
Answer: =-x+7
Step-by-step explanation:
Answer:
M = 84
Step-by-step explanation:
Opposite angles in a quadrilateral inscribed in a circle are supplementary
R+ M = 180
96+ M = 180
Subtract 96 from each side
96-96+M = 180-96
M =84
Answer:The method of substitution involves three steps: Solve one equation for one of the variables. Substitute (plug-in) this expression into the other equation and solve. Resubstitute the value into the original equation to find the corresponding variable.
