w = number of weeks
b(w) = number of books read after w weeks
====================================
b(w) = 12 translates to "after w weeks, Katy will have read 12 books" or put another way "Katy will have read 12 books after w weeks". The 'w' is a placeholder for some number
====================================
b(2) = 10 means "Katy has read 10 books after 2 weeks". We use the same basic idea talked about above, but we replace w with 2. At the same time, we use 10 instead of 12.
====================================
b(3) = f means "Katy has read f books after 3 weeks" or "after 3 weeks, Katy has read f books". Like w, the f is a placeholder for some number.
x=9 because the triangle is equilateral which means every side is equal to 60. When you do the math you get 7x-3=60 which is 7x=63 and 63/7=9
Answer:
Step-by-step explanation:
So we have y-3=2(x+4)
So the first thing we want to do is distribute the 2 in front of the (x+4)
2(x+4) = 2x+8
Which means we have:
y-3=2x+8
Remember we need to get it into the form y=mx+b
As you can see here the 3 is preventing our equation from being in that form to we need to add it to both sides. This leaves us with:
y - 3 + 3 = 2x+8+3
Which gives: y = 2x+11
Therefore the slope form of this equation is y = 2x+11
Answer:
The answer is 4!
Step-by-step explanation:
2 + 2 can be rewritten as 1+1+1+1
both equal 4
By using a tens number as you refer to a multiple of ten. As a multiple of ten you can just add it to another number easier than a ones number
