Answer:

Step-by-step explanation:
Given expression:



Replace 900 with 30² :




(We need to use the absolute value of √x² since the x term was originally to the power of 2, which means the value of x² is always positive since the exponent is even).


Simplify:

(We need to use the absolute value of z³ since the z term was original to the power of 6, which means the value of z⁶ is always positive since the exponent is even).
Answer:
The second equation is correct.
y=2.25x + 4
Step-by-step explanation:
We can systematically eliminate the others.
For equation 3 and 4, 6.5*2 and 12*x is already bigger than 8 of the first set of numbers.
For equation 1, 2*x+8.5 is also bigger than 8 from the first set.
Plugging in the values to equation 2, we always get the correct cost.
Answer:
The GCF is -10
Step-by-step explanation:
-10 in the highest/largest number that goes into both -20 and -50.
if you have to factor -20v-50 as well it would be:
-10(2v+5)
and to check if that answer is correct, distribute -10 inside the parenthesses:
-10 times 2v = -20v
-10 times 5 = -50
-20v-50
