Are these lines parallel?

Mathematics

C is the answer!

Step-by-step explanation:

The slope of points P and Q is,

m=y2-y1/x2-x1

substitute the numbers in the equation above,

m=2-3/4-8

m=-1/-4

m=1/4

The slope of points R and S,

m=-2-(-5)/-1-(-5)

m=-2+5/-1+5

m=3/4

Remember, that parallel lines have the SAME SLOPE!

So no, the lines are not parallel!

Find equations of both the tangent lines to the ellipse x^2 + 4y^2 = 36 that pass through the point (12, 3).y = (smaller slope)y
Bingel [31]

Answer:

x+y=15

Step-by-step explanation:

Given equation of x^2+4y^2=36

Differentiating both side 2x+8y\frac{dy}{dx}=0

\frac{dy}{dx}=\frac{-x}{4y}

It passes through the point (12,3) so

\frac{dy}{dx}=\frac{-12}{4\times 3}=1

So equation of tangent passing through (12,3) is

y-12=-1(x-3) as y-y_1=-m(x-x_1)

So x+y =15 will be the equation of tangent which passes though the point (12,3)

How do you graph y=7/2x-2
RoseWind [281]
You can either make a table using any numbers you would like (I would suggest -5 to 5) and then graphing the rule

ex. (7/2)(-5)-2 = -19.5 (I multiplied (7/2) by -5 and then subtracted 2) 


Or you can put the rule in a graphing calculator and check the points from there
