Answer:

  C.  2y = (2x-1)/4

Step-by-step explanation:

An equation is linear when the exponents of the variables are 1 and the sum of the exponents of the variables in any term is 1.

a) 3xy = 4 . . . . sum of exponents is 1+1=2

b) f(x) = 2/3(1 -x^2) . . . . exponent is 2

c) 2y = (2x -1)/4 . . . . all exponents are 1 (linear)

d) y = 3/(x+1)  ⇒  xy +y = 3 . . . . sum of exponents is 1+1 = 2

Whats the slope of the line? (Multi choice)<br> 1. 1/2<br> 2. -1/2<br> 3. 2<br> 4. -2
otez555 [7]

Answer:

1. 1/2

Step-by-step explanation:

     With a graph that has easily see-able points, slope can be calculated with rise over run, or change in y divided by change in x

\frac{2-1}{2-0} =\frac{1}{2}

      What does the \frac{1}{2} mean? From any point, the next point will be up one and over to the right two. Since the graph is going from bottom left to top right, it is positive.

Have a nice day!

     I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)

Trig please help
enot [183]

Answer:

One

Step-by-step explanation:

9/sin(34) = 6/sinC

sinC = 0.372795269

C = 21.9, 158.1

Since 158.1 + 34 = 192.1 > 180

It will not form a triangle

So,

Only one triangle with angle 21.9° at C
