Answer:
q=-1/3
Step-by-step explanation:
Evaluate the exponent
Multiply the numbers
Add the numbers
Evaluate the square root
Multiply the numbers
For this one, plug in your <em>x </em> and <em>y</em> intercepts for the corresponding letters and see which one is true. I always start with the first equation and then see which ones solve it first, that will cut your time down on a test.
Lets start with A. (4,5)
and the first equation y=x+1
5=4+1, which is true so A is a potential answer
B. (2,3)
3=2+1, B is a potential as well
C. (-2,1)
1=-2+1, which is false so C is out
D. (-4,-3)
-3=-4+1, which is true.
To cut down on time, do the same thing with the second equation and your final answer will be A. (4,5)

Answer:
-16
Step-by-step explanation:
The absolute value function gives the positive value of the argument, so this is ...
-4|-4| = -4·4 = -16

Answer:
[ 4, ∞ )
Step-by-step explanation:
Given
8(x - 5) - 3x ≥ - 20 ← distribute and simplify left side
8x - 40 - 3x ≥ - 20
5x - 40 ≥ - 20 ( add 40 to both sides )
5x ≥ 20 ( divide both sides by 5 )
x ≥ 4
Solution set is [ 4, ∞ )
