Answer:
6 or 2
Step-by-step explanation:
f(x) = 0.5|x - 4| + 6
0.5|x - 4| + 6 = 7
0.5|x - 4| = 7-6
0.5|x - 4| = 1
|x - 4| = 2
x -4 = ± 2
x-4 = 2 ==> x = 6
x-4 = -2 => x = 2
so the value of x = 6 or 2
Answer:
31
Step-by-step explanation:
They're technically asking you to find the missing angle. 61+57 is 118. 180-118 is 62. Since they're asking 2x, you do 62 divided by 2, which is 31.
√81 =9
it is an odd, whole, rational number.
Answer:
You can prove this statement as follows:
Step-by-step explanation:
An odd integer is a number of the form where . Consider the following cases.
Case 1. If is even we have: .
If we denote by we have that .
Case 2. if is odd we have: .
If we denote by we have that
This result says that the remainder when we divide the square of any odd integer by 8 is 1.
