the right side of the image is truncated,

but "A" seems to be the answer....

take (2,3) and (3,4)

#1) y2-y2/x2-x1 ... 4-3/3-2 = 1 ... slope = 1

#2 ) y = 1x + b

#3 plug in (2,3) ... 3 = 1(2) + b ... B=1

#4 Y= 1 x + 1

Shalinda wants to leave an 18% tip for her
ki77a [65]

Hello There! Shalinda's total is $29.62.

Our first step is to find 18% of $25.10. To do this, multiply 25.10 by 0.18.

25.10 x 0.18 = 4.518 (Which can be rounded up to 4.52)

So, this gives us the tip, but the question is asking what her total is, including the tip. To find her total, add the price before tip and the tip together.

25.10 + 4.52 = 29.62

So, her total with the tip is $29.62! I hope this was helpful, have a great day!

The distance between port M and port N is 162m. A ship left port M with a speed of 45 mph. In 45 minutes another ship left port
matrenka [14]

Answer:

After 900 minutes

Step-by-step explanation:

when we convert the velocities of the ships into miles/ min we get

45mph=45m/60min=0.75m/min

36mph=36m/60min=0.6m/min

The equations determining the distances  of the ships from the port M (set at x=0) are

D_1=0.75t (for 45mph ship)

D_2=162+0.6(t-45) (for 36mph ship)

The solution to these equation lie at t= 900 minutes; therefore the two ships will meet 900 minutes after the departure of the first ship.
