Can you please graph the following function:y=3x-1

To graph a linear function you need to determine two points of said function, plot them in the coordinates system and link them by a line.

The most easy point to find is the y-intersect. This is the value of y when x=0

Replace it in the equation:

\begin{gathered} y=3x-1 \\ y=3\cdot0-1 \\ y=-1 \end{gathered}

The y-intersect is (0, -1)

To determine the second point you have to select any value of x of your choise and replace it in the formula to determine the y-coordinate.

For example: x=4

\begin{gathered} y=3x-1 \\ y=3\cdot4-1 \\ y=11 \end{gathered}

The coordinates for the second point are (4, 11)

Now plot both points in the coordinate system and the line.

Which of the following is equivalent to the expression below for x≠6?
nata0808 [166]

Answer:

The fourth answer choice is the correct one:  2(x - 3)

Step-by-step explanation:

2x²-18x+36/x-6 should be factored, as follows:

2(x²-9x+18) / (x-6) = 2(x - 3) (x - 6) / (x - 6)

Substituting x = 6 would result in division by zero and is thus not allowed.

Remembering this, we can reduce 2(x - 3) (x - 6) / (x - 6) to 2(x - 3) for x≠6.

If A is a 5 by 7 matrix, what is the maximum rank that A can have?
amm1812

Answer:

5

Step-by-step explanation:

Remember, the rank of a matrix is the number of pivots or number of rows different of zero in the echelon form of the matrix.

Then, if A is a matrix 5\times 7 the maximum number of pivots that can have is one by row, that is, 5.

Then the maximum rank that A can have is 5.
