It's D! This is because all of the angles add up to 180 degrees.
The answer is NOT A, because 90+90+90 is 270, which is greater than 180, so not a triangle.

Please I need help on this question, A line passes through (6,3), (8,4), and (n,-2). Find the value of n.

Vika [28.1K]

Answer:

n= -4

Step-by-step explanation:

First we have to find the equation of line which passes through (6,3) and (8,4).

Then we have to pass this line through the point (n , -2).

we know, equation of line passing through (x1,y1) and (x2,y2) is

$\frac{x-x1}{x1-x2}=\frac{y-y1}{y1-y2}$

So, the equation of line passing through (6,3) and (8,4) is

$\frac{x-6}{6-8}=\frac{y-3}{3-4}$

or, $\frac{x-6}{-2} =\frac{y-3}{-1}$

multiplying both sides by -2

x-6=2(y-3)

or, x-6=2y-6

or, x-2y=6-6

or, x-2y=0

Now, we have to pass this line through (n,-2)

So, using the point in the line, that is using x=n , y=-2

we get

n-2(-2)=0

or, n+4=0

or, n=-4

Please show your work !!!!!!!!!!!!

dedylja [7]

Answer:

$(3.4)$

Step-by-step explanation:

Our equation is $f(x)=-2(x-3)^2+4$
Now there are 2 ways you can do this, I'll show you the shortcut
If you have an equation like this, just take the value in parenthesis and equate it to zero
$x-3=0.x=3$ is the x of the vertex
Put this back into the equation
$f(x)=-2(x-3)^2+4\\x=3\\f(3)=-2(3-3)^2+4\\f(3)=-2(0)^2+4=4$ this is the y
