Let's plug in y=3x-7 into 2x+4y=14
2x+4 (3x-7)=14
Distribute
2x+12x-28=14
Add
14x-28=14
Add 28 to both sides
14x=42
Divide
X=3
Y=3 (3)-7
Y=9-7
Y=2
(3,2) A the solution is (3,2)
C or A could be the answer
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.
Matt would get about $4 and 90 cents back from the clerk, since 10 dollars minus $5 and 10 cents equals $4 and 90 cents.
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.
We are required to find the points that lie on the number line.
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.
Adding the points=-2+2=0
Hence the two points that lie on the number line that can be combined to make zero are 2 and -2.
