The function that have the same graph as x + y = 11 is the function 3x + 3y = 33
<h3>What is an equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
An independent variable is a variable that does not depends on other variable while a dependent variable is a variable that depends on other variable.
Given the function, x + y = 11. To get another function with the same graph, multiply by a constant:
(x + y) * 3 = 11 * 3
3x + 3y = 33
The function that have the same graph as x + y = 11 is the function 3x + 3y = 33

Answer:
a)
The point that is equidistant to all sides of a triangle is called the <u>incenter</u>.
The incenter is located at the intersection of bisectors of the interior angles of a triangle.
b)
The point that is equidistant to all vertices of a triangle is called the <u>circumcenter</u>.
The circumcenter is located at the intersection of perpendicular bisectors of the sides of a triangle.
c)
<em>See the attachment</em>
The blue lines and their intersection shows the incenter.
The red lines and their intersection shows the circumcenter.
As we see the red point- the <u>circumcenter </u>is closer to vertex B.
Use the cos rule
cos^-1(18^2+28^2-12^2 divided by 2*18*28
Which is 16.99 degrees, which is 17 (option d)
