-3x+8=y solve for if the equation is a function or non function
Ket [755]

Answer:

The equation is a function

Step-by-step explanation:

-3x + 8 = y

Reverse the function.

y = -3x + 8

Draw a graph of y vs x  (below)

To determine if the relation is a function,  we can use the vertical line test:  

If a vertical line crosses the graph more than once in any location, the relation is not a function.

We see that at no place will a vertical line intersect the graph more than once.

The relation is a function.

Geometry ( WILL GIVE BRAINY)
Step2247 [10]

Answer:

1:

we have a rule that is (n-2)×180

while n = number of sides

2:

exterior angle of a polygon = 360 ÷ number of sides

so 360÷25=14.4

3:

octagon is 8 side, so as we said: (8-2)×180 = 1080

4:

lets make an equation, we know that (n-2)×180 = the sum

so (x-2)×180=720

180x -360 = 720

180x = 1080

x=6
