Mary is spending money at the average rate of $5 per day. After 14 days she has $68 left. The amount left depends on the number
Radda [10]

Answer:

A. Y-68=-5(x-14)

Step-by-step explanation:

Mary is spending money at the average rate of $5 per day. After 14 days she has $68 left. The amount left depends on the number of days that have passed. write an equation for the situation

We find the equation using the point slope equation of a line. This is given as:

y - y1 = m(x-x1)

The slope intercept form will be

y = -5x + b

since the amount decreases by $5 per day...

Our slope is -5 so m=-5

We have a point (x1,y1) = (14, 68)

Hence, we have:

y-68 = -5(x-14)

Option A is correct

What is the surface of a cylinder radius 8mm height of 20 mm
LiRa [457]
Hey there :) You'll have to use the formula of cylinder to get your answer :
Surface area of cylinder : 2(pi)(r^2) + 2(pi)(r)(h)
pi = 22.7 or 22/7
r (radius of cylinder) = 8 mm
h = height of cylinder = 20mm

●Hence, just substitute your answer in the given formula and also don't forget to check whether the answer required needs to be in mm or cm.

Hope it helps :)
