Since x represents the number of students, and y represents the number of adult chaperones (and x does not include y), the best answer is A, that there are x = 50 students on the field trip, and they are accompanied by y = 5 chaperones.
Note the difference with choice c, which says that 50 is the total (45 students, 5 adults).
F(x)=-2if-1
f’(x)=d/dx (-2fi-1)
F’(x)=0
Answer:
A1(-5,-5)
Step-by-step explanation:
given : A(-6,-2)
simply apply the translation to the coordinates above
A1 ( -6 + 1, -2-3) = A1(-5,-5)
Answer:
D. [0,4]
Step-by-step explanation:
We are provided with the graph of height of seesaw with respect to time.
The new graph is transformed from the function y = cosx,
It is required to find the range of the transformed function.
Now, as we know the range (i.e. the values where y varies) of cosx is [-1,1] and the new function is a transformed version of cosine function.
So, the values of y are varying from minimum value 0 to maximum value 4 in the given graph.
Hence, the range of the transformed function is [0,4].
Answer:
<em>15</em>
<em> + 7x + 12</em>
Step-by-step explanation:
(6x^2 + 7x + 2) - (-9x^2 - 10)
Flip the sign:
- (-9x^2 - 10) becomes + 9x^2 + 10
Combine like terms:
6x^2 + 7x + 2 + 9x^2 + 10
6x^2 + 9x^2 = 15x^2
2 + 10 = 12
Put it all together:
15x^2 + 7x + 12
