Is y=1/2 + 3 porportional if so why

No.

Step-by-step explanation:

The function represents a proportional function. Because the y-intercept is , all proportional functions pass through the origin. represents some constant that represents the relationship between and entirely.

The function has a y-intercept of 3 and therefore does not pass through the origin. Thus, is not a proportional function.

5x+10 is the correct one

hope this

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
