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
Answer:
718.5
Step-by-step explanation:
First, you see how many times 4 can go into 28. Then divide by 74. To get 718.5
30.25 square meters because you would divide 121 by 4 because a square has 4 equal length sides.
Hope this helps

Constant in a mathematical expression is a term whose value never changes.
The terms with x and y will vary based on the variable x and or y.
