F(n) = y and n = x

just a matter of subbing...I will be subbing 6 in for y and 2 in for x
A. f(n) = n + 3
    y = x + 3
    6 = 2 + 3
   6 = 5 (nope...so its not A)

B. f(n) = 1/3n
     y = 1/3x
     6 = 1/3(2)
     6 = 2/3 (nope....not this one either)

C. f(n) = 3n
      y = 3x
      6 = 3(2)
      6 = 6 (got it.....its this one)

samantha threw an apple out of a window from the tenth floor of her appartment building. the equation y = -16t^2+120 can be used
ella [17]
Answer:
time taken = 2.74 seconds

Explanation:
We are given that:
y = -16t² + 120 models the situation where:
y is the floor number
t is the time taken for the apple to hit the ground

We are also given that the floor number (y) is 10. Therefore, all we have to do is substitute with y in the above equation and solve for the time t as follows:
y = -16t² + 120
10 = -16t² + 120
120 - 10 = 16t² 
110 = 16t²
t² = 110/16
t² = 6.875
either t = 2.74 seconds ..........> accepted
or t = -2.74 seconds .........> rejected as time cannot be in negative

Hope this helps :)

The expression (X + 3)(x + 2) is the product of two binomials. Which expression is also a product of binomials?

Binomials are expressions containing the sum (or difference) of two terms.

A. is not the answer because pq and qp are <u>products</u>.

C. is not the answer because 3x is not a sum/difference.

D. is not the answer because it is one binomial, not two muliplied together.
