Solve for x. x3 = 216

vampirchik [111]

I'm assuming the equation is x^3 = 216 or $x^3 = 216$ (both mean the same thing)

If so, then the solution to x^3 = 216 is x = 6

<span>We can find this by taking the cube root of both sides
</span>x^3 = 216
x = 216^(1/3) .... 1/3 power means cube root
x = 6

Checking the answer:
x^3 = 216
6^3 = 216
6*6*6 = 216
216 = 216
Answer is confirmed

So once again the answer is x = 6. This is assuming the initial assumption made at the top of the problem holds up.

What is the output, or y-value, when you input x = -3 into the function: x² − 3x + 1

Citrus2011 [14]

Answer:

y = 19

Step by step explanation:

$y = x ^{2} - 3x + 1 \\ y = ( - 3) ^{2} - 3( - 3) + 1 \\ y = 19 \\ so \: the \: y - value \: is \: 19$

Given: 2x + b > -3. Find the value of b so that x > 3<br>Help a s a p please

masya89 [10]

Answer:

Step-by-step explanation:

To find the value of b, we need to isolate it on one side of the inequality. We can do this by subtracting 2x from both sides, which gives us b > -3 - 2x.

Since we want x to be greater than 3, we can plug in the value 3 for x on the right-hand side of the inequality. This gives us b > -3 - 6, or b > -9.

Therefore, the value of b that makes the inequality true is any value that is greater than -9. For example, b could be -8, -7, -6, or any other value that is greater than -9.

To check if our solution is correct, we can plug in the value of b and the value of x (3) into the original inequality to see if it is true. If we plug in -8 for b and 3 for x, we get the inequality 2x + b > -3, which simplifies to 2 * 3 + (-8) > -3, or 6 - 8 > -3, which is true. Therefore, our solution is correct.
