$(x^3)^2\\\\x^{3*2}\\\\x^6$

$x^{-2}*x^3\\\\x^{-2+3}\\\\x^1\\\\x$

$x^2*x^{-3}\\\\x^{2-3}\\\\x^{-1}\\\\\frac{1}{x}$

Is x = -7, the solution to -11 + 2x = -26? Justify your answer in complete sentences.

Natali5045456 [20]

First of all, you can move the +2x to the other side:
-11 = -26 - 2x

Then you can move the -26 to the other side and then simplify:
-11+26 = -2x
15 = -2x

Then you can divide both sides by 2:
7.5 = -x

Then you can flip the sides and the signs around:
x = -7.5

No, The answer is not -7, it is -7.5
Hope this helps! :)

Answer:

$\displaystyle x=\frac{-8\pm\sqrt{(8)^2-4(4)(-221)}}{2(4)}\ \text{; x = 6.5 and x = -8.5}$

Step-by-step explanation:

Subtract the right side of the given equation to put it into standard form:

4x² +8x -221 = 0

Then the coefficients used in the quadratic formula are ...

a = 4
b = 8
c = -221

When these are filled into the form ...

$\displaystyle x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

the result is as shown above.
