The lengths are $\frac{5}{6} \frac{5}{12} and \frac{1}{3}$
finding the LCM we get
$\frac{10,5,4}{12}$
arranging them
$\frac{1}{3} \frac{5}{12} and \frac{5}{6}$

Write the Equation of the line that has a slope of -2 and passes through the points (9,5)

AlladinOne [14]

Start with the point-slope formula shown at the top in red.

Now, substitute your slope and coordinates in the formula.

Then distribute and combine lie terms.

Finally, add 2x to both sides to get your equation in standard form.

If -xy+ 1 + x^2 = 2y then find the equations of all tangent lines to the curve y= -2

Black_prince [1.1K]

Answer:

(see attached workings)

y = -4x + 2

y = (4/5)x + 2/5

Step-by-step explanation:

Rewrite the function to make y the subject.
Find the x values of the points when y=-2 by substituting y=-2 into the rewritten function
Differentiate the function
Input the found values of x into the differentiated function to find the gradients of the tangents to the curve at y=-2
Use the equation of a straight line and the points where y=-2 and the found gradients to find the equation of the tangent lines.
