Answer:
false statement
Step-by-step explanation:
5+x^2=2x^2+13
5+x^2-2x-13=0
-8+x^2-2x^2=0
-8-x^2=0
-x^2=8
x^2=-8
this statement is false for any value of x because the power function with an even exponent is always postive or 0
Answer:
Step-by-step explanation:
Use substitution, y=3x+18 so -12x+4(3x+18)=-24. From here you can try to solve for x
-12x+12x+72=-24
The xs cancel, which leaves you with 72=-24
Since 72 cannot equal -24 there is no answer to this system of equations
Answer:
<em>m</em> > 6
Step-by-step explanation:
