Distribute
2x+12x-28=14
Add
14x-28=14
Add 28 to both sides

Given: g(x) = x - 4 and h(x) = 2x - 8,
kvasek [131]
Plug in 10 for x in h(x) then simplify
h(10)=2(10)-8
h(10)=20-8
h(10)=12

h(10) is 12 so put 12 in for g(x)
g(h(10))=12-4
g(h(10))=8

Here’s everything together
g(h(10))=(2(10)-8)-4
=(20-8)-4
=(12)-4
=8

This is what I’ve always done. I can’t really tell what your answers are so sorry if this isn’t right at all.

yarga [219]

The two points that lie on the number line that can be combined to make zero are 2 and -2.

Given that the points which lie on the number line when combined make zero.

Number line is basically a horizontal line that has equally spread number increments. The points increase from left to right direction.

Points that lie on the number line are -2,2.
