9.(03.06 MC) Write the equation of the line that passes through the points (1, 7) and (5, 15) using function notation. (5 points)
O y = 2x + 5
O y = 4x + 8
Of(x) = 2x + 5
f(x) = 4x + 8

  answer:

  write 548 as 500 + 40 + 8. multiply each addend by 5. then add the three products to get 2,740.

we know that

1) the inscribed angle measures half of the arc it comprises.

so

m∠dgf= > expression

2) the opposite angles in an inscribed quadrilateral are supplementary angles

so

m∠dgf=

m∠dgf=°

substitute in the expression to find the value of arc ef

therefore

the answer is

the measure of the arc ef is
