Is the ordered pair (8, 4.5) a solution to the function y=3/4x-1/2?

To determine whether or not (8, 4.5) is a solution to y=3/4x-1/2, substitute 8 for x and 4.5 for y:

4.5 = (3/4)(8) - (1/2)

4.5 = 6 -        0.5

4.5 = 5.5

No, (8, 4.5) is not a solution of the given function.

i dont know men

step-by-step explanation:

(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
