Answer:
A reflection is not a function because the image could overlap the pre-image.
Step-by-step explanation:
The function 5w+2 is set up like a slope intercept form function (y=mx+b) where the function of w would b the number of pears each week, 5 is the slope, and 2 is the y-intercept. One could assume that the number of pears increases each week by a factor of five and the 2 is the initial 2 pears on the tree from when Carl started watching the tree grow.
Answer:
Dan is correct, and Nadia is not.
Step-by-step explanation:
Dan is correct because he used PEMDAS, (parenthesis, exponents, multiplication, division, addition, and subtraction). Nadia did not use PEMDAS correctly. Therefore, Dan is correct, and Nadia is not.
Try this option:
1. according to the condition new ratio of maple trees (m.t.) is 3:11 and number of o.t. is 132. It means
number of m.t. after the bug.
2. total number of trees after bug problem is 132+36=168. According the condition it is the same number as before the big problem. Using this,
3. 5x+9x=168 - total number of the trees before big problem, where 5x is number of o.t. and 9x is number of m.t.
x=168/14=12 and
4. ⇒ 9x=9*12=108 m.t. before the big problem.
answer: 36 m.t. and 108 m.t.
P.S. before the big problem 108 m.t. and 5*12=60 o.t., after the bug 36 m.t. and 132 o.t.
Think about what the question is asking... When does that cost reach 0?
Solve for when f(x) = 0
