Given:
Dimensions of rectangular garden are (-7x-3) feet by (9x+2) feet.
Cost of oak fencing = $11 per foot
To find:
The cost of total oak fencing around her garden.
Solution:
Let,
Length of the garden, l = (-7x-3) feet
Width of the garden, w = (9x+2) feet
So, the perimeter of garden is (4x-2) fee.
Cost of oak fencing is $11 per foot. So, total cost is
Therefore, the total cost of oak fencing is 44x-22x.
Answer:
Step-by-step explanation:
The area of a triangle with height and base
is given by
. By definition, the base and the height must intersect at a 90 degree angle. Therefore, the diagram gives a base of 14 cm and a height of 8 cm. Substituting these values, we get:
Answer:
y = -x - 1
Step-by-step explanation:
y = mx + b
m = slope
b = y-intercept
On the graph, the point on the y-axis is the y-intercept. That point is (0, -1). So the y-intercept is -1.
To find the slope, find two points and put it in the slope equation.
Point A: (0, -1)
Point B: (-1, 0)
m =
Point A:
Point B:
m =
m =
m = -1
y = -1x - 1
In other words, y = -x - 1
