Its just a matter of subbing to find out...
4x + 20 = 12y....when x = 5 and y = 0
4(5) + 20 = 12(0)
20 + 20 = 0
40 = 0......nope....(5,0) is not a solution
Approximate <em>R'</em> by using a linear approximation: for <em>x</em> close enough to 24, you have
<em>R'(x)</em> ≈ <em>L(x)</em> = <em>R' </em>(20) + <em>R''</em> (20) (<em>x</em> - 20)
Then
<em>R'</em> (24) ≈ <em>R'</em> (20) + <em>R''</em> (20) (24 - 20) = -4 + 50 (24 - 20) = 196
The answer is 293 meters because you multiply the 14650 books by how thick they are which is 0.02, and that should reveal your answer. Hope this helps!
Answer:
The answer is 5a-35.
Step-by-step explanation:
So, since you told me to explain, if a number is right next to a parentheses without any signs you multiply it.
But instead of doing 5 times 7a, you multiply both of them separately.
5 times a is pretty much just 5a. 5 times -7 is -35.
As a result, you will be left with 5a-35.
