3x(2) + 2(2x - 20) = 16 - 2x(2)
6x + 4x - 40 = 16 - 4x
10x - 40 = 16 - 4x
14x - 40 = 16
14x = 56
x = 4
Hope this helps! ;)
Answer:
Step-by-step explanation:
using your f(x) I want to show you how to plug in different things itnot he function.
f(x) = -x + 4
f(1) = -1 + 4 = 3
f(2) = -2 + 4 = 2
f(m) = -m + 4
f(abc) = -(abc) + 4
f(h(x)) = -h(x) + 4
Does that help? what if you replaced h(x) with g(x)? Of course you already have that x so you could make it a little simpler as well. Let me know if you don't quite get it.
Answer: C) Find the factors of c that add up to b.
==============================================
Explanation:
If we want to factor something in the form x^2+bx+c, then we look for two numbers that
-------------
Let's look at a specific example
Consider factoring x^2+5x+6
We need to find two numbers that...
- Multiply to c = 6
- Add to b = 5
Through trial and error, you should find the two numbers to be 3 and 2. This means it factors to (x+3)(x+2). The order of the factors doesn't matter.
You can use the FOIL rule or the box method to expand out (x+3)(x+2). You should get x^2+5x+6 again.
Answer:

Step-by-step explanation:
Answer:
A. 81
Step-by-step explanation:
Combine fractions, that equals 2/5 in your exponent. Three to the 2/5 power is 81. So answer A.
