C
Step-by-step explanation:5 days times how much she works per day need to be at least or greater than 240 hence why the sign is greater than or equal too.
The answer is B or it should be
Answer:
B.(x, y)→(2.5x, 2.5y)
Step-by-step explanation:
Answer:
The final answers are n = 0 or n = -1/4.
Step-by-step explanation:
Given the equation is -5n(4n + 1) = 0.
The Zero-Product property says "if x*y=0, then x=0 or n=0 or both."
we have -5n(4n + 1) = 0.
We know -5 is not equal to 0.
It means n = 0 or 4n+1 = 0.
n = 0 or 4n = -1.
n = 0 or n = -1/4
So, final answers are n = 0 or n = -1/4.
In this equation, y = mx + b where m is the slope. So on 17, the slope is -5. On 18, the slope is 1/3.
