What is the slope of a line perpendicular to the line whose equation is
3x + 3y = 45. Fully simplify your answer.

Answers



Put 3x + 3y = 45 in slope intercept form

y = 15 - 3/3x
(-3/3x is just going to simplify to -1x though)

Perpendicular form of -1x would be 1x

So your perpendicular slope would be 1

If K is the ratio of the roots of the polynomial x²+px-q, the value of k/1+k² is:​

Answers

[tex]\large\underline{\sf{Solution-}}[/tex]

Given Polynomial:

[tex] \rm \longmapsto f(x) = {x}^{2} + px - q[/tex]

Let α and β be the zeros of f(x)

Then:

[tex] \rm \longmapsto \alpha + \beta = - p[/tex]

[tex] \rm \longmapsto \alpha \beta = - q[/tex]

Now, it's given that:

[tex] \rm \longmapsto k = \dfrac{ \alpha }{ \beta } [/tex]

Consider the expression given:

[tex] \rm = \dfrac{k}{1 + {k}^{2} } [/tex]

[tex] \rm = \dfrac{ \dfrac{ \alpha }{ \beta } }{1 + { \dfrac{ \alpha {}^{2} }{ \beta {}^{2} } }} [/tex]

[tex] \rm = \dfrac{ \dfrac{ \alpha }{ \beta } }{ { \dfrac{ \alpha {}^{2} + { \beta }^{2} }{ \beta {}^{2} } }} [/tex]

[tex] \rm = \dfrac{ \alpha }{ { \dfrac{ \alpha {}^{2} + { \beta }^{2} }{ \beta } }} [/tex]

[tex] \rm = \dfrac{ \alpha \beta }{\alpha {}^{2} + { \beta }^{2} } [/tex]

Find the coordinates of D:

x = 1 + 1/4(17 - 1) = 1 + 4 = 5y = 5 + 1/4(1 - 5) = 5 - 1 = 4

Find the coordinates of E:
