Please help me with this thanks
Ronch [10]

If x = 1, then 3*1 = 3 which when modded with 5, we get 3 as a remainder. In other words, 3/5 = 0 remainder 3. We don't use the quotient at all when it comes to modular arithmetic. All we care about is the remainder.

If x = 2, then 3*2 = 6 which leads to remainder 1 when we divide by 5. Therefore, 3x = 1 (mod 5) when x = 2.

If x = 3, then 3*3 = 9 = 4 (mod 5) because 9/5 = 1 remainder 4.

So 3x = 4 (mod 5) when x = 3.

<h3>The final answer is C) 3</h3>

We don't need to check D since x = 3 is a solution and it's smaller than x = 4.

If you wanted to check x = 4, then 3*4 = 12 = 2 (mod 5) because 12/5 yields a remainder of 2.

I've done the y = equations but I don't know how to do this one.
Tems11 [23]

Consider the equation

-10x-y=-20

1) First row of the table

Set x=0 and solve as follows:

\begin{gathered} -10(0)-y=-20 \\ \Rightarrow-y=-20 \\ \Rightarrow y=20 \end{gathered}

The answer is y=20 and the pair x-y is (0,20)

2) Second row

Set x=1 and solve, as follows:

\begin{gathered} -10(1)-y=-20 \\ \Rightarrow-10-y=-20 \\ \Rightarrow-y=-10 \\ \Rightarrow y=10 \end{gathered}

The answers are y=10 and (1,10)

3) Third row.

Set y=0 and solve as follows:

\begin{gathered} -10x-(0)=-20 \\ \Rightarrow-10x=-20 \\ \Rightarrow x=\frac{20}{10}=2 \\ \Rightarrow x=2 \end{gathered}

The answers are x=2 and (2,0)

Name a point that is not coplanar with points A, B, and C.
boyakko [2]
Points are coplanar if they are located on the same plane. A plane is one of the undefined terms in geometry. It is described as a flat surface in a two-dimensional area. If you look at the given figure, find points that are not included in the shaded plane of points A, B and C. That would be point M or point D.

Which of the following is not a function
aleksandr82 [10.1K]

Answer:

The ellipse is not the graph of a function.

Step-by-step explanation:

If you can draw a vertical line on the graph that intersects the graph in two or more points, the relation shown is <em>not a function</em>.

A vertical line will intersect the ellipse at two points (unless it is tangent to an end of the major axis), so the ellipse is not the graph of a function.
