There is a math graping app called desmos it can help you graph the equation and give you the intercepts
Answer:
y = 1/3x - 10/3
Step-by-step explanation:
Perpendicular lines have slopes that are negative reciprocals of one another so m = -1/3
Given (-1,-3)
y = mx + b
-3 = -1/3(-1) + b
-9/3 = 1/3 + b
b = -10/3
so y = 1/3x - 10/3
That is a parabola.
All domain of a parabola are, (-∞,∞).
The range would be, (-∞, 0]

Exact Area = 1200 - 300pi square cm</h3><h3>
Approximate Area = 257.522203923062 square cm</h3>
Work Shown:
The area of the rectangle is 40*30 = 1200 square cm
Note how we have 4 circles along the horizontal dimension which is 40 cm, so each diameter is 40/4 = 10 cm, and the radius is 10/2 = 5 cm
Each circle has an area of pi*r^2 = pi*5^2 = 25pi
There are 4*3 = 12 circles, so the circle areas combine to 12*25pi = 300pi
Using a calculator, we find that 1200 - 300pi = 257.522203923062 approximately. Round this however you need to.
Answer:
The number of adults attended was 600
Step-by-step explanation:
Let
x ----> the number of children attended
y ----> the number of adults attended
we know that
-----> equation A
----> equation B
Solve the system by graphing
The solution of the system of equations is the intersection point both graphs
using a graphing tool
The solution is the point (200,600)
see the attached figure
therefore
The number of children attended was 200 and the number of adults attended was 600
