Answer:

  b. fundamental arithmetic

Step-by-step explanation:

While fundamental arithmetic is required when solving linear equations, the use of it is not a named <em>method of solution</em>.

"Substitution", "Elimination", and "Graphing" are named methods of solving linear equations. Sometimes the line can be blurred between substitution and elimination, but these methods generally involve distinct sets of steps (which include the use of fundamental arithmetic).

Graph function 1/2y=sin(3x+180)
sweet [91]

Answer:

The graph of the given function is shown below.

Step-by-step explanation:

The given function is

\frac{1}{2}y=\sin (3x+180)

Multiply both sides by 2.

y=2\sin (3x+180)      ....(1)

The general form of sine function is

f(x)=a\sin(bx+c)+d    ....(2)

Where, a is altitude, b is period, c is phase shift and d is vertical shift.

On comparing (1) and (2), we get

a=2,b=3,c=180

it means the altitude of the function is 2, period is 3 and phase shift is 180.

The graph of the given function is shown below.

Mrs Smith has 12 times as many markers as color pencils the total number of markers and colored pencils is 78 how many markers d
yawa3891 [41]
<em>x = markers</em>
<em>y = colored pencils</em>

12x = y

x= 72
y = 6

Okay, so what I did was divide 78 by 12 (to find the number of colored pencils) which gave me 6.5. You can't have half a colored pencil, so I rounded the number down to get 6. To find the number of markers, I multiplied 12 and 6 <em>(12x = 6) </em>which gave me 72. To check my answer I added the two amounts, 72 + 6, which gave me 78.
