J= -2(3-k) make k the subject

lapo4ka [179]

Answer:

K=J+6/2

Step-by-step explanation:

J= -2(3-k)

simplify whats in the bracket

J= -6+2k

J+6=2k

Divide both sides by 2

J+6/2=2k/2

2 and 2 will cancel out

remaining K

So, Therefore K=J+6/2

Find an equation for the line with the given properties. Perpendicular to the line 7x - 3y = 68; containing the point (8, -8)

Sever21 [200]

Answer:

$y=\dfrac{-3}{7}x-\dfrac{32}{7}$

Step-by-step explanation:

Given that,

A line 7x - 3y = 68 and containing the point (8, -8).

The equation can be written as :

$-3y=68-7x\\\\y=\dfrac{68}{-3}+\dfrac{7x}{3}\\\\y=\dfrac{7x}{3}+(\dfrac{-68}{3})$

The slope is :7/3

Line is perpendicular so use m = –3/7

$-8=(-\dfrac{3}{7})\times 8+b\\\\-8+\dfrac{3}{7}\times 8=b\\\\b=\dfrac{-32}{7}$

So, required equation is :

$y=\dfrac{-3}{7}x-\dfrac{32}{7}$

Hey! I would appreciate some help with this

arsen [322]

Answer:

...

Step-by-step explanation:

since they give us the side opposite of the given angle(Opposite) and we are trying to find for a (Adjacent/side), so we use TOA

tan(30)= $\frac{4}{a}$

i see u dont want it solved but ill solve it anyways

since a is on the bottom then lets switch them

$x=\frac{4}{tan30}$

x= 6.928
