Find the y intercept!

Mathematics
1 answer:

Answer:

  -23

Step-by-step explanation:

We note that as x increases by 36 from -72 to 36, y decreases by 24 from 25 to 1.

Increasing x from -36 by another 36 to zero will correspond to a decrease in y by another 24 from 1 to -23.

The y-intercept is -23.

_____

You could go to the trouble to use these observations to compute the slope as -24/36 = -2/3. Then you could pick one of the points and write the equation in point-slope form as ...

  y = -2/3(x +36) +1 . . . point-slope form with m=-2/3, (h, k) = (-36, 1)

  y = -2/3x -24 +1 . . . . . eliminate parentheses

  y = -2/3x -23 . . . . . . . y-intercept is -23

5. they give dimes of 2 identical sides 25 & 5

25/5 = 5 so ABC is 5 times larger so 12 x 5 = 60

6. V= L x W x H/3 = 6.2 x 4.5 x 5.3 = 147.87/3 = 49.29 cubic cm

going against the current a boat takes 6 hours to make a 120 mile trip when the boat travels with the current on the return trip
Irina18 [472]
Speed against current = 120 miles / 6 hours = 20 miles / hour
Speed with current = 120 miles /5 hours = 24 miles / hour.

Speed of boat in still water = (20+24)/2 = 22 miles / hour
