Ok so imagine G=gasoline and D equals the discounted price
It would be G-20=D
6x^3 a negative times a negative cancels out making it positive
It's basically multiplying 0.4 6 times
Standard form is Ax + By = C. We need to subtract 11y. This gives us 8x + 11y = 24.
The standard form of 8x = -11y + 24 is 8x + 11y = 24.
Answer:
a. From x = -2 to x = 0, the average rate of change for both functions is negative
d. The quadratic function, y = x², has an x-intercept at the origin
Step-by-step explanation:
From x = -2 to x = 0, the rate of change is negative because both functions are going in a downward slope. The quadratic function y = x² touches the x-axis right at (0, 0), meaning it has an x-intercept at the origin.
The second answer is incorrect because y = x² does not intersect the other parabola at (2, 3). The third is incorrect because y = x² + 3 does not even touch the x-axis. The fifth is incorrect because the rate of change is negative, not positive. Finally, the sixth is incorrect because y = x² + 3 does not intersect the other parabola at (2, 7). Hope this helps! Feel free to ask any questions!
