The absolute value of a number is how far away it is from 0 on a number line.
Example) 2 is two numbers away from 0, but neg. 2 (-2) is also two numbers away from 0
So basically. A positive number has the absolute value of itself. (2= a value of 2) and negative numbers have the absolute value of the positive form of that number. (-9= a value of 9)
Numbers that have the absolute value of 2: 2 and -2
Numbers that have the absolute value of 4: 4 and -4
Numbers that have the absolute value of 9: 9 and -9
You are looking to add your numbers together to make a positive.
So the answer is the positive answers to the absolute values: 2,4,9
2+4+9=15
15 is a positive number.
Answer: c
Step-by-step explanation:
33.24 / 12 = 2.77
44.80 / 16 = 2.80
41.10 / 15 = 2.74
(/ means divide)
Check the picture below.
you simply come "clockwise" to get the negative angle.
and to get the positive angle, simply go around 2π and then add π/7 to it.
Answer: it would be g because if you distribute 9, you end up with x+72 and the bottom one is 9•8 (also 72)+x
3. g(x) = (x-3)^2 -5
Replace g(x) with y
y = (x-3)^2 -5
Switch the x and the Y:
x = (y-3)^2 -5
Solve for y:
Add 5 to both sides:
x + 5 = (y-3)^2
Take the square root of both sides:
+ /- SQRT(x+5) = y -3
Add 3 to both sides:
y = +/- SQRT(x +5) +3
The solution is both the positive and negative:
SQRT(x +5) +3 and -SQRT(x+5) +3
7. Following the same steps as 3
The answer is SQRT(x-2) -6 and -SQRT(X-2) -6
9. Following thw same steps as 3.
The answer is SQRT(2(x+4)) +2 and - SQRT(2(x+4))
