C.
Willy and Bill rode an equal distance on their bikes
Hope it help! :D
Y = -5/2(x + 4) + 7
y = -5/2x + (-10) + 7
y = -5/2x - 3
The two y’s are like term so it is possible to subtract. So 3y-y=2y
Answer:
Constant of Proportionality is 50.
Step-by-step explanation:
Albatross can fly 400 kilometers in 8 hours.
'd' represents the distance and 't' represents the number of hours.
The equation
represents the relationship between the distance and time.
Now, in the equation shown above 50 is the constant of proportionality, and 50 represents the rate of change of distance with time.
The constant of proportionality tells us the rate of change between two variables.
So for every 1 hour of time the distance covered is 50 kilometers.
Answer: AB = 8.4 BC = 12.4
Explanation:
Start of by solving AB using SOH CAH TOA and primary trig ratios;
AB is the opposite side and AC is the hypotenuse, so we use sin.
sin34 = AB/15
15 • sin34 = AB
8.4 ≈ AB
then, solve for BC
cos34 = BC/15
15 • cos34 = BC
12.4 = BC
