Answer:
y intercept is 18
Step-by-step explanation:
It is given that
Monthly rent for phone service = $18
charges for each long distance minute = $ 0.07
Let us assume number of minutes used = x
also let us represent total cost by y
So the total cost = ( charges per minute )(number of minutes) + monthly rent
now we compare this equation with y=mx+b
where m is the slope and b is y intercept
so we have b= 18
hence y intercept is 18
The gardens perimeter is 12 meters.
Explanation:
- The garden has a 4m length and a 2m width. The perimeter of any given rectangle is two times the sum of the length and the width of the same rectangle.
- Perimeter = 2 × (length of the rectange + width of the rectangle)
Perimeter = 2 × (4m + 2m) = 2 × (6m) = 12 meters.
- So the gardens perimeter is equal to 12 meters.
- Ramond needs to buy a fence for a garden whose parameter is 12 meters.
Length of the rectangle is 8 units
Step-by-step explanation:
- Step 1: Find the length, let width be x.
Area of the rectangle = 48 units
Length = x + 2
⇒ Area = Length × Breadth
48 = x (x + 2)
48 = x² + 2x
x² + 2x - 48 = 0
x² + 8x - 6x + 48 = 0 (Product Sum rule to factorise)
x(x + 8) - 6(x + 8) = 0
(x - 6)(x + 8) = 0
⇒ x = 6, -8 (negative value is neglected)
∴ x = 6
x + 2 = 8
