Please help me lol a lil confused

$\leadsto f( \rm x) = - (x - 3)(x - 5)$

$\\ \\$

$\leadsto f( \rm x) = - ( {x}^{2} - 5x - 3x + 15) \\$

$\\ \\$

$\leadsto f( \rm x) = - ( {x}^{2} - 8x + 15) \\$

$\\ \\$

$\leadsto f( \rm x) = - {x}^{2} + 8x - 15 \\$

What is the equation of the line h Th ya has a y intercept of (0,-3) and passes through the point (-9,-9)

Nikolay [14]

Answer:

The line equation is given as: 3 y = 2 x - 9

Step-by-step explanation:

Here, Y intercept is at point ( 0.-3)

So, at x = 0, y = -3

or, C = -3

Also, the point on the equation line is (x,y) = (-9,-9)

Now, by SLOPE INTERCEPT FORM of a line equation,we get:

y = m x + C : m = slope of line ......... (1)

So, substituting the values of C and (x,y) , we get:

-9 = m (-9) + (-3)

or, -9 + 3 = - 9 m

or, m = -6/-9 = 2/3

or, m = 2/3

Now, substitute the value of m back in to the line equation (1)

$y = m x + C \implies y = (\frac{2}{3}) x - 3\\\implies 3y = 2x - 9$

Hence, the line equation is given as: 3 y = 2 x - 9.

How far apart are the foci of an ellipse with a major axis of 20 feet and a minor axis of 14 feet?

omeli [17]

The solution for this question is simple. First we need to divide both numbers by 2 which will give us 10 and 7. This is the equation x^2/10^2 + y^2/7^2 = 1sqrt(100-49) = 7.14 (the answer do not have a perfect square root)
Foci are 14.28 units apart
