Answer:
2327.49 ---> 25 hrs
starting plot points (0,640) and ending (25, 2327.49)
Step-by-step explanation:
b = 640
r = 5.3% = 0.053
t = 25
y = 640 ( 1 + 0.053)^25
y = 640 ( 1.053)^25
y = 2327.49 ---> 25 hrs
starting plot points (0,640) and ending (25, 2327.49)
Answer:
The y-coordinate would be 17.5
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
Let
y ----->material needed in yards
x ----> number of curtains
we know that
For y=5, x=2
Find the value of the constant of proportionality k
substitute the given values of x and y
The linear equation is equal to
If the x-coordinate was 7
then
substitute in the equation x=7 and solve for y
therefore
The y-coordinate would be 17.5
