Answer:

Yes.

Step-by-step explanation:

This is a function because if you used the vertical line test, no dot is repeated. There can only be one point on either quadrant of the graph.

(3, y) and (9, -9); slope: -4/3<br>Find y<br>PLEASE HELP

aleksley [76]

For this case we have that by definition, the pendeinte of a line is given by:

$m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}}\\(x_ {1}, y_ {1}) :( 3, y)\\(x_ {2}, y_ {2}) :( 9, -9)$

Substituting according to the data we have:

$- \frac {4} {3} = \frac {-9-y} {9-3}\\- \frac {4} {3} = \frac {-9-y} {6}\\6 * - \frac {4} {3} = - 9-y\\-8 = -9-y\\y = -9 + 8\\y = -1$

Answer:

$y = -1$

Question 1 Simplify the following expression: (5x2 + 3x + 4) − (2x2 − 6x + 3). If the final answer is written in the form Ax2 + Bx + C, what is the value of B?
Solution:
5x^2 + 3x + 4 - 2x^2 + 6x - 3 = 3x^2 + 9x + 1
Then, B = 9 Hope this helped=)
