Answer:
Step-by-step explanation:
<u>Even function has following property:</u>
<u>It is easy to show this works with the second choice only. All the others don't work:</u>
- g(x) = (x - 1)² + 1
- g(-x) = (-x - 1)² + 1
This is not correct as x - 1 ≠ -x - 1 so as their squares, so g(x) ≠ g(-x)
The last two choices are not even similarly.
If C is between A and B, then, we can write the equation
Substitute the value of AB and the expressions for AC and CB in terms of x.
We can now solve for x.
Dividing by 5.
<span>A) -5u + 2x = 22
B) -u - 6x = -34
</span>Multiplying A) by 3
A) -15u +6x = 66
B) -u -6x = -34 Then adding the 2 equations:
-16u = 32
u = -2
x = 6
You're asking for the square root of 32. you can actually do this on a calculator really easily. just type in the number (in this case, 32) and press the square root symbol (looks like a calculator). the square root of 32 is a long string of decimals, but it's approximately 5.7 :) good luck
B. 5.2! If you use a calculator it gives you the direct answer. If you don't have one use paper and illustrate it.
