T 1 2 3 4
B 3 6 9 12
This is linear relationships B=3*T (it can be also called directly proportional)
Ur answr would be 154.50 because if u do 30.90 5 times or times 30.90 by 5 its 154.50
3r=10+5s
3*10=10+5s
30=10+5s
30-10=5s
20=5s
s=4
r=10
I’m pretty sure it’s 6 1/3
Answer:
Bryan walks faster
Bryan was farther away from home when he started walking.
Step-by-step explanation:
Given the following :
Brendon's distance in feet from home 'y' in relation to the number of minutes walked 'x'
y = 7,920 − 270x
For bryan:
Minutes (x) - - - 0 - - - - - 15
Feet ( y) - - 8000 - - - 3800
General form of a linear equation :
y = mx + C
m = gradient / slope
m = (y2 - y1) / (x2 - x1)
m = (3800 - 8000) / (15 - 0)
m = -4200 / 15 = - 280
Intercept 'c' = 8000 (where line intersect the y axis), (since y = 8000, when x = 0)
Therefore,
Bryan's model:
y = 8000 - 280x
Comparing both functions :
Bryan has a greater speed ( from the gradient)
Bryan was farther away from home when he started walking ( intercept )
