What is the inverse function of d(x ) = -2x - 6?
do not answer if you're not sure

First make the equation equal y

Y=-2x-6

Then rearrange to make x the subject

2x=-y-6

X=(-y-6)/2

Then change the y's to x's

Inverse=(-x-6)/2

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

-4

step-by-step explanation:

do 6-10=

if u need it to be negative.
