Answer:
22.05
Step-by-step explanation:
i used a calculator
The like terms are:
12x and 8x - they have the same variables
8, 55, 3, and 180 - they are all regular numbers (if you know what I mean)
Answer:
z^12
Step-by-step explanation:
(z^6)^2 is equivalent to z^(6·2), or z^12. Here we have multiplied the exponents 6 and 2 together, obtaining 12.
This obeys the rule of exponents (z^a)^b = z^(ab).
The answer is y = 5x + 7
here's how you get it:
Start with the base y = mx + b
then imput the points and the slope:
-3 = 5 ( -2 ) + b
Then solve for b
-3 = 5 ( -2 ) + b
-3 = -10 + b
-b = -7
b = 7
so the equation is:
y = 5x + 7
