Which expressions are equivalent to -6n+(-12)+4n

Mathematics
1 answer:
GaryK [48]3 years ago
5 0

Answer:

-2n - 12

Step-by-step explanation:

Combine like terms. Note that each term has one variable (n). Also note  that one negative sign and one positive sign results in a negative sign.

-6n + (-12) + 4n = -6n  + 4n - 12 = -2n - 12

-2n - 12 is your answer

Find the real numbers x and y.<br> 27+yi= 11-x + 4i
Korvikt [17]

\quad \huge \quad \quad \boxed{ \tt \:Answer }

\qquad \tt \rightarrow \:x = -16

\qquad \tt \rightarrow \: y =4

____________________________________

\large \tt Solution  \: :

\qquad \tt \rightarrow \: 27 + yi = 11 - x + 4i

\qquad \tt \rightarrow \: yi + x = 11 + 4i - 27

\qquad \tt \rightarrow \: x + yi =  - 16 + 4i

By equating both equations we get :

\qquad \tt \rightarrow \: x =  - 16

\qquad \tt \rightarrow \: y = 4

I’m so confused on what numbers l should put into the boxes
Serggg [28]

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The lines for the given statements can be plotted as shown below.

<h3>What is the equation of a line?</h3>

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of line is given by,

y =mx + c

where,

x is the coordinate of the x-axis,

y is the coordinate of the y-axis,

m is the slope of the line, and

c is y-intercept.

The lines for the given statements can be plotted as shown below.

The coordinate grid can be filled as,

1)

x        0         3         1

y        3         0         2

2.)

x        0         1         -1

y         1         0          2

3.)

x         0         4         -1

y         -2         0          2

4.)

x         0         1           1

y         -2         0         -2

Which set of ordered pairs represents y as a function of x?
Serjik [45]

Answer:

D{(0, 0), (-1, -0.5), (-2, -1), (-3, -1.5), (-4, -2)}

Step-by-step explanation:

A function is a relation in which we take every element of the first group and assign an unique element of the second group.

So, the set of ordered pairs that represents y as a function of x is the set that take every value of x and assign an unique value of y.

Then, the set A is not a function because we have the ordered pairs (3,9) and (3,16) in which we have two values of y for the value of x=3.

At the same way, we can said that B and C aren't functions.

Finally, D is the set of ordered pairs that represents y as a function of x because every x has an unique value of y.
