Answer:

Step-by-step explanation:

You'll be given an equation that contains an x and a y.

You'll also be given an ordered pair. Plug the ordered pair into the equation and see if the equation is true.

For example:

Is (0,4) a solution to the equation 2x+3y = 15 ?

Plug the coordinates of (0,4) into the equation:

2·0 + 3·4 = 15

This simplifies to 12 = 15, which is obviously false, so (0,4) is not a solution to the equation.

which of the following are remote interior angles of 5? check all that apply. a 4 b 5 c 6 d 1 e 2 f 3
77julia77 [94]
From my research, the image supports the question. The exterior angle 5 can have up to 2 remote interior angles. Remote interior angles are the two angles inside the triangle that do not share a vertex with the external angle. From the choices, the two remote interior angles are 1 and 3. Among the choices, the correct answers are D and F.

Could you please help me with questions 36 & 37?
Andrej [43]

We have to determine if the functions are linear or not.

We can do this by rearranging the equations in this form:

y=mx+b

where m and b are constants.

<em>NOTE: There are many ways to prove that a function is linear, but this is the easiest for this question. </em>

36.

\begin{gathered} x+\frac{1}{y}=7 \\ \frac{1}{y}=-x+7 \end{gathered}

As this function can not be written in the form y=mx+b, then it is not linear.

37.

\begin{gathered} \frac{x}{2}=10+\frac{2y}{3} \\ \frac{x}{2}-10=\frac{2y}{3} \\ \frac{2y}{3}=\frac{1}{2}x-10 \\ y=\frac{3}{2}(\frac{1}{2}x-10) \\ y=\frac{3}{4}x-15 \end{gathered}

This function is now in the form y=mx+b, where m=3/4 and b=-15. Then, this function is a linear function.

Answer:

36. Non-linear.

37. Linear.
