The domain is [0,4], as the x-values go from 0 to 4.
The range is [0,4], as the y-values span from 0 to 4.
The relation is a function
- For a relation to be a function, each x-value can have only one, distinct y-value. This is the case for this relation, as each x-input has only one corresponding y output.
D=rt and we are told d=546 and r=1.3m/s so
1.3t=546 divide both sides by 1.3
t=420 seconds so
420s(min/60s)=7 min
So it takes him 7 minutes to walk to Sara's house.
Answer:
Step-by-step explanation:
a) -3
b) 5
c) -2
d) -6
Slope intercept form is y = mx + b
Pick one of the coordinates, I’ll use (-3,-4) as the example.
Coordinates are just numbers plugged in for (x,y).
This means -3 would be your x and -4 would be your y.
So plug these numbers into the equation and you get -4 = m(-3) + b.
M is slope and to find slope, you need to do (y2-y1) / (x2-x1).
In other words, it would be (-3 - -4) / (4 - -3) = 1/7 which is your slope (m).
Now plug that in for m to get the b variable.
-4 = 1/7(-3) + b.
B = -3.57
Your answer is y = 1/7x -3.57
The answer is D my dude don’t over think. Since it’s are multiply your answer choices till you reach 60.75
