Plug 8 for y
8 = 2x + 4
Subtract 4
4 = 2x
Divide by 2
x = 2
Plug 16 for y
16 = 2x + 4
Subtract by 4
12 = 2x
Divide by 2
x = 6
Substitute 20 for y
20 = 2x + 4
16 = 2x
x = 8
Substitute 22 for y
22 = 2x + 4
18 = 2x
9 = x
So the values are 2, 6, 8, 9
Answer:
+3
Step-by-step explanation:
(-m)^(-3) = -m^3, since (-1)^-3 = 1 / (-1).
If m = 2 then we have -2^(-3), or -1 / [2^3]), or -1/8.
Finally, if n = -24, the original expression becomes
(-1/8)(-24) = +3
Second problem: Only the first expression simplifies to a negative result.
Answer:
No.
Step-by-step explanation:
f(x) = 3x^4-4x^2-3
If a function is odd then f(-x) = -f(x) for all values of x.
Here f(-x) = 3(-x)^4 - 4(-x)^2 - 3
= 3x^4 - 4x^2 - 3
So f(-x) = f(x) which makes it even.
Answer:
9
Step-by-step explanation:


9
92 can be rounded to 90
68 can be rounded to 70
90 x 70 = 6300
