If anything there might be an eraser icon (modification notes) so you might want to click on that and read it. If not, post what it says or give the math teacher a call. I hope this helps!
Answer:
All values of x are solutions
Step-by-step explanation:
−15x+4 ≤ 109 OR −6x + 70 > −2
-15x ≤ 105 OR -6x > -72
-x ≤ 7 OR -x > - 12
x ≥ -7 OR x < 12
Answer
x ≥ -7 OR x < 12
All values of x are solutions
Answer:
a = 2/3
Step-by-step explanation:
A cube root is the same as a 1/3 power. The square of that gives a 2/3 power.
a = 2/3

<em>Additional comment</em>
You can see the relationship between a root index and an exponent if you consider what the root means.
Consider a cube root, for example. When you cube the root, you get the original number:
(∛x)·(∛x)·(∛x) = x
Now, let's write the root as a power of x: x^a.
(x^a)·(x^a)·(x^a) = x . . . . . where x^a = ∛x
We know this product is ...
x^(a+a+a) = x^(3a) = x^1
This tells us that ...
3a = 1 ⇒ a = 1/3
That is, ∛x = x^(1/3).
Of course an n-th root is multiplied by itself n times to get the original number, so the corresponding exponent is x^(1/n).
Property being demonstrated here is corresponding angles.
Meaning 72 = x.
