9. A trapezoid is graphed on the coordinate plane. Which transformation maps the trapezoid onto itself? A. rotation of 90° C. reflection over the x-axis B. rotation of 180° D. reflection over the y-axis

$3720

step-by-step explanation:

taxable income = $31000

as per the 2018-2019 us tax bracket, the tax rate is 12% for an individual whose taxable income is between $9,526 to $38,700.

so, the tax to be paid by him = 12% of 31000

= 0.12 * 31000     [12% converted to decimal as 0.12]

= $3720

the answer on ed. is:

c. "the graph of f(x) has exactly two x-intercepts."

hope i could someone! : )

the answer is  

c.

14,469 cubic feet

i know this one is right

< 4 = < 5 they are vertical angles

120 degrees
