Solve y = x^2 - 18 for x.

Mathematics
1 answer:
viva [34]4 years ago
3 0

Answer:

x = √y+18

Step-by-step explanation:

Given

y = x^2-18

In order to solve the equation for x, we have to isolate x on one side of the equation

So,

y+18 = x^2 -18 + 18\\y + 18 = x^2

We have to find the value for x, so taking square root on both sides

\sqrt{x^2} = \sqrt{y+18}

Solving the squre root

x = x = \sqrt{y + 18}

Hence,

x = √y+18 is the correct answer ..

How many ways are there to select 3 of 15 flavors of juice at the grocery store?
m_a_m_a [10]
First, you need to distinguish if this is a permutation or a combination. The difference between the two is the order. In combination, order does not matter. Since there is no any restriction given, we assume this is a combination problem. The equation of determining the number of ways to choose 'r' objects out of total 'n' objects is:

Number of ways = n!/r!(n-r)! = 15!/3!(15-3)! = 455

There are 455 ways.
