Answer:
1
Step-by-step explanation:
y2-y1 divided by x2-x1
12-3 divided by 20-11
which equals to 9/9 which equals to 1
Answer:
y=20,x=9
When doing problems like this it is important to always note: whatever you do to one side of the = sign you have to do to the other side.
Step-by-step explanation:
For this problem it helps that they already give you what y equals to so you can plug y in the top equation to figure out what x is. See attachment for step by step process
Answer:
8
Step-by-step explanation:
There are several ways of doing that, but probably the simplest one is to use the formula
where the vertices are
and the bars | | means that you take the positive value of the number inside. For example | -3 | = 3.
Our vertices are
Replace the values in the formula and we have
H>43
at least 43 hours. (Sorry, didn't quite understand the question either! Just wanted to try and help!)
