Vertex form is:
f(x) = -5(x+10)^2 + 508
Answer:
C
Step-by-step explanation:
it's a sideway parabola (expressed as x=......) plus it does not have any x<0 as you can see in the graph, so x must be always positive for every value of y
20 miles say thank you plssss and bye
Hello there!
(5x - 2)(4x² - 3x - 2)
Use the distributive property
=(5x)(4x²) + (5x)(-3x) + (5x)(-2) + (-2)(4x²) + (-2)(-3x)² + (-2)(-2)
= 20x³ - 15x² - 10x - 8x² + 6x + 4
= 20x³ - 23x² -4x + 4
As always, it is my pleasure to help students like you. Let me know if you have any questions.
I'm pretty sure the answer would be D) P = 20.2x + 1.3 but the answer should be P = 19.2x + 1.3, but it isn't listed so it would be D
