She has 90 markers because 18 times 5 is 90
1. C.
The rule of powers is that when a parenthesis is raised to a power, you multiply the two numbers. Since it is being raised to the second power, it needs to have a 10 in the parenthesis. That would make 20.
2. B
Firstly 10^2 = 100, so we know that the number must be 10. That leaves us with just A and B. Then we know the same thing from the previous equation, that they need to be multiplied together.
(-2, 0) and (0, -2)
slope = (0+2)/(-2 - 0) = -1
b = -2
slope intercept equation
y = -x - 2
compare equation from given
y - 3 = -(x + 5)
y - 3 = -x - 5
y = -x - 5 + 3
y = -x - 2 (matched slope intercept equation)
answer is A
y - 3 = -(x + 5)
Answer: -ab - 11a^2 - 3b + 3a
