Liana started to evaluate the function f(x) = 2x2 – 3x + 7 for the input value 2.f(x) = 2(2)2 – 3(2) + 7

= 2(4) – 3(2) + 7

What is the value of the function when x = 2?

Answers

f(x) = 2x² - 3x + 7

x = 2

f(2) = 2(2²) - 3(2) + 7
f(2) = 2(4) - 6 + 7
f(2) = 8 - 6 + 7
f(2) = 15 - 6
f(2) = 9

The value of the function when x = 2 is 9.
If you would like to know the value of the function when x = 2, you can calculate this using the following steps:

f(x) = 2 * x^2 - 3 * x + 7
x = 2
f(2) = 2 * 2^2 - 3 * 2 + 7 = 2 * 4 - 6 +7 = 8 - 6 + 7 = 9

The correct result would be 9.

i am a three digit number. i am divisible by 5. i am an even number each of my digits are different my tens is greater than my ones digit. my hundreds digit is greater than my tens digit. i am less than 400. i am divisible by 3. i have only one odd digit. my tens digit is 1. what number am i?

Answers

Answer:

210

I am divisible by 5.

So your ones digit is 0 or 5

I am an even number.

So your ones digit is 0.  We fill that in.

_ _ 0

My tens digit is 1.

So we fill that in.

_ 1 0

 

My tens digit is greater than my ones digit.

Well, of course 1 is greater than 0. We didn't need to be told that.

I have only one odd digit.

Since the 1 is odd, the hundreds digit is even, 2,4, or 8

I am less than 400.

So your hundreds digit is 2.  Fill that in and we're done.

2 1 0

My hundreds digit is greater than my tens digit.

Of course 2 is greater than 1, we didn't need to be told that.

I am divisible by 3.

Of course 210 is divisible by 3.  We didn't need to be told that.

 

Too much information!

Find the LCM of 8,9, and 12

Answers

It's very simple, take a look.

8, 9, 12 | 2
4, 9,  6  | 2
2, 9, 3  |  2
1, 9, 3  | 3
1, 3, 1  | 3
1,  1, 1

2² * 3² *2 = 72


LCM(8,9,12) = 72
The LCM of 8, 9, and 12 is 72. That is the Lowest Common Multiple.
