Step-by-step explanation:
![( {2 x})^{ \frac{1}{3} } - 7 = \sqrt[3]{2x} - 7](https://tex.z-dn.net/?f=%28%20%7B2%20x%7D%29%5E%7B%20%5Cfrac%7B1%7D%7B3%7D%20%7D%20%20-%207%20%3D%20%20%5Csqrt%5B3%5D%7B2x%7D%20%20-%207)
X/x-2 >= 0 equals x/x >= 0+2 simplified x >=2
Answer:
8
Step-by-step explanation:
1) Lets rewrite the expression in expanded form to make is easier to understand:
(8*8)÷(2*2*2)
2) Simplify the interior of the parenthesis:
(64)÷(8)
3) Divide:
8
Answer:
(0, -3) and (3, 0)
Explanation:
1st equation: y = x² -2x - 3
2nd equation : y = x - 3
Using substitution method:
x² -2x - 3 = x - 3 <em>exchange sides</em>
x² - 2x - x - 3 + 3 = 0 <em>simplify</em>
x² - 3x = 0 <em> take common factor</em>
x(x - 3) = 0 <em>simplify</em>
x = 0, 3
Solve for y:
when x is 0, y = x - 3 = 0 - 3 = -3
when x is 3, y = x - 3 = 3 - 3 = 0
