Mathematics

Pani-rosa [81]3 years ago
8 0

Answer:

See attachment

Step-by-step explanation:

The table that represent a direct variation is shown in the attachment.

To determine a direct variation from tables, you need to inspect the y-intercept of each table.

If there is a table with y-intercept of 0, then it represents a direct variation.

Or you could check the table with equation of the form: y=kx if you cannot see zero in the y-intercepts directly

Which quadratic equation has the roots -1+4i and -1-4i
AysviL [449]

Answer:

C

Step-by-step explanation:

Solve the quadratic in answer choice C using the quadratic formula:

x=\frac{-b+/-\sqrt{b^2-4ac} }{2a}.

Here a=1, b=2, and c=17.

Substitute and you'll have:

x=\frac{-b+/-\sqrt{b^2-4ac} }{2a} =\frac{-2+/-\sqrt{(-2)^2-4(1)(17)} }{2(1)}=\frac{-2+/-\sqrt{4-68}}{2)}

\frac{-2+/-\sqrt{-64} }{2}=\frac{-2+/-8i }{2}=-1+/- 4i

Sarah too advertising department from her company on a round trip to meet with a potential client. Including Sarah a total of 8
FromTheMoon [43]

Answer:

<em>y = 8</em>

Step-by-step explanation:

330x + 1220y = 12730    (cost of coach tickets plus cost of first class tickets is total budget)

x + y = 17    (number of coach tickets plus number of first class tickets is total number of people)

Solve the second equation for y to get y = 17 - x, then plug that into the first equation and solve for x:

330x + 1220(17 - x) = 12730

330x + 20740 - 1220x = 12730

-890x + 20740 = 12730

-890x = -8010

x = 9

Sarah bought x = 9 coach tickets. Plug that into the second equation and solve for y:

9 + y = 17

y = 8

Sarah bought y = 8 first class tickets.
