First, let's get the unit rate.
1.5 hours for 915 miles, so
![\frac{1.5 hours}{915 miles} = \frac{1 hour}{x.miles}](https://tex.z-dn.net/?f=%5Cfrac%7B1.5%20hours%7D%7B915%20miles%7D%20%3D%20%20%5Cfrac%7B1%20hour%7D%7Bx.miles%7D)
Cross multiplying gives us 1.5x = 915, divide by 1.5, and we get 610 miles. This is the answer for the top left. This means the plane was going 610 mph.
The speed will be constant because it tells us this.
Then, we multiply 610 by the time to fill in the rest of the distances.
For <em>t</em>, we can figure out the distance is 610 times <em>t</em>, as you can see I have written down.
See attached file below.
I hope this helps, have a nice day! :D
Answer:
Price of power meow cat food = $38.55
Step-by-step explanation:
Price of whisker cat food = $12.85
Price of power meow cat food = x
Whisker cat food = ⅓ * power meow cat food
12.85 = ⅓ x
X = 3 * 12.85
X = $38.55
Price of power meow cat food is $38.55
F(x) = 4x + 1
g(x) = x² - 5
(f - g)(x) means subtracting g(x) from f(x). So we can write:
So option c is the correct answer
Answer:
-4x^3 +x^2+4x-3
Step-by-step explanation:
Answer:
Graph C represents a decreasing function.
Step-by-step explanation:
Graph A: Since y does not change when x increases from 0 to 6, this graph (a horizontal line) represents a constant function. REJECT this choice.
Graph B: The line connecting (0, 0) to (6, 6) is a straight line with slope +1; it's an increasing function. REJECT this choice.
Graph C: As we go from (0, 5) to (6, 0), y decreases by 5. Thus, this is the correct answer choice.
Graph D is a vertical straight line; its slope is undefined. REJECT this choice.
