Which statements are true based on the diagram? Check all that apply.

GrogVix [38]

First statement: False. Points K, M and N form a triangle.
Second statement: True. Points J, K, and Q are on the same line.
Third statement: False. KN and MQ intersect at N, not at R.
Fourth statement: False. JQ and KM intersect at K, but MQ does not pass through it.
Fifth statement: True. By definition, there is always only 1 line that can be drawn between 2 given points.

If f(x) = 2x - 1 and g(x) = x^2 - 2, find [g · f](x)<br><br> please show me how to do this

larisa [96]

Answer:

(x² -7)/(2x + 1)

Step-by-step explanation:

f(x) = 2x+1 and g(x) = x² -7

thus: (g/f)(x) = g(x)/f(x) = x² -7/2x + 1

Graph the line passing through the given point and having the given slope (0,3), m=4

andriy [413]

<u>Hint </u><u>:</u><u>-</u>

To find out the equation of the line we can use the point slope form of the line which is $y - y_1 = m(x-x_1)$

<u>Solution</u><u> </u><u>:</u><u>-</u>

The given point to us is , $(0,3)$ and the slope of the line is 4 . On using the point slope form , we have ,

$\implies y - y_1= m(x-x_1) \\\\\implies y-3 = 4(x-0) \\\\\implies y -3 = 4x \\\\\implies \boxed{ 4x - y + 3 =0}$

<u>Hence</u><u> the</u><u> </u><u>equation</u><u> </u><u>is </u><u>4</u><u>x</u><u> </u><u>-</u><u> </u><u>y </u><u>+</u><u> </u><u>3</u><u> </u><u>=</u><u> </u><u>0</u><u> </u>
