52= 2(w-8) + 2x
X is the unknown length because the question is only telling us one side of the rectangle
Answer:
Using the y = b^x formula
Step-by-step explanation:
Turn the text into an eqation:
48-x = 4x-7
5x = 55
x = 11
The line equation for its slope and one point is:
y - y1 = m(x - x1)
m is the slope, x1, y1 are the point coordinates, so lets substitute:
y - 4 = (1/2)(x - 2)
y = <span>(1/2)x + 3</span>
Alicia : y = 43 x
For x = 1 ( 1 hour ):
y = 43 miles, v = 43 mph
Trish: 69 = v * 1.5
v = 69 : 1.5
v = 46 mph
Alicia: 43 mph
Trish: 46 mph
The woman who drives at a slower rate is : A ( Alicia )
