Step-by-step explanation:
you drew already the right things, you have everything.
so, what is the problem ?
the most common form of line equation is
y = ax + b
a is the slope of the line. it is expressed as the ratio
y coordinate change / x coordinate change
when going from one point to the other.
b is the y-intercept (the y value when x = 0).
once we have the slope, we get b by using the coordinates of one of the given points as x and y in the equation and solve for b.
so, for the 2 marked points you showed correctly the differences :
x changes by +8 (from -4 to 4).
y changes by -2 (from 3 to 1).
so the slope is -2/+8 = -1/4
the y-intercept we also see directly in the chart : +2.
A=p (1+r/k)^kt
A=500×(1+0.02÷3)^(3×4)
A=541.50
Answer:
Please see attached graph
Step-by-step explanation:
We know that the equation tht represents the boats avlue is given by
A(x) = 400(b)^x + 0 = 400(b)^x
A(x) = 400(b)^x
An increment in the rate of 25% a yeard is given by
b = 1.25
A(x) = 400(1.25)^x
Which graph can be seen below
Answer:
53 cm.
Step-by-step explanation:
Circumference = pi times diameter
We are trying to find diameter so rearrange
Circumference/pi = diameter
166.5/pi = 52.998596
Approximately 53 centimeters of lace
5 pounds= 80 ounces
total cost= ($0.44×1)+($0.20×79)=$16.24
