The table below shows the average distance an airplane flies over time. The relationship between the two quantities is proportional,
Time (hours)
1
2
3
Distance (miles)
350
700
1050
1400
w
Whats the rate of change in the distanEthearplanetlies over time?
A 350 miles per hour
700 miles per hour
C 1050 miles per hour
D 1400 miles per hour

my guess would be b and d, but i didn’t actually get out the pen and paper. lol

step-by-step explanation:

answer: the is put the 450

step-by-step explanation:

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0
