Answer:
Length = 21 yards
Width = 15 yards
Step-by-step explanation:
Let
Length = x
Width = x - 6
Perimeter ≤ 71 yards
Perimeter of a rectangle = 2 (length + width)
72 ≤ 2(x + x-6)
72 ≤ 2 (2x - 6)
72 ≤ 4x - 12
72 + 12 ≤ 4x
84 ≤ 4x
x ≤ 84/4
x ≤ 21
Length = x = 21 yards
Width = x - 6
= 21 - 6
= 15 yards
Answer:
A parabola is continuous but for y to be function of x the axis must be parallel to the y axis and for x to be a function of the y axis must be parallel to the x axis
Mx+b=y m is your slope which u can find by using two point see how far the x are and the y are then the y/x is your slope. Then he is your starting value so what y is when x= 0
Answer:
The bottom one: The value is the difference of 42 and the sum of 20 and 3.
Step-by-step explanation:
The answer is what you get when you subtract 23 from 42. Using "the difference" means subtraction is involved and you expression is 42 - (minus) (20+3).
We must find the difference between prices. $2.65 - $2.50 = $0.15. Now we need to calculate what percent $0.15 is of $2.65. It is 5.7%! The price decreased, so it is a 5.7% decrease!
