Answer:
33.33 gallons
Step-by-step explanation:
1000 miles divided by 30 miles per gallon.
Answer:
The line passes through (4, -7) and (5, -10).
Step-by-step explanation:
When x = 4, y = 5 - 3(4), or 5 - 12, or -7. Thus the point (4, -7) lies on the graph. Similarly y = 5 - 3(5) = -10 when x = 5. Thus, the line also goes through (5, -10). Plot these two points and draw a line through them. Doing this will result in the desired graph.
This is a stupid question. The teacher who asked this needs to go back to school.
A = x⁴ - 9y²
That's going to be a number. As long as it's positive we can choose any length for our rectangle L and we can compute the width by W=A/L. So the correct answer is the dimensions are L by (x⁴ - 9y²)/L.
They don't want the correct answer. They want you to factor this expression. We'll do it, but don't believe for a second this factoring somehow constrains the possible dimensions of some rectangle.
We use the difference of two squares, a²-b² = (a+b)(a-b)
A = x⁴ - 9y² = (x²)² - (3y)² = (x²+3y)(x²-3y)
Answer: x²+3y by x²-3y
Answer:45$
Step-by-step explanation:5 + 8(5)
5 + 40= 45
Answer:
Step-by-step explanation:
We can use the decay equation:
- M(0) is the initial mass
- M is the mass after t (1000 days) time
- λ is the decay constant
But:
So, we can rewrite the initial equation:
Now, we just need to solve it for t(1/2):
I hope it helps you!
