Answer:
Q(18) is a mathematical representation of the weight in pounds of a puppy after 18 months.
Q(30) = 27.5 ; This means that the weight of puppy after 30 months will be 27.5 pounds
Step-by-step explanation:
Given the expressions :
Q(18)
Q(30) = 27.5
Function Q gives a puppy's weight in pounds as function of its age in months
What does each expression represent in this situation?
A function is generally represented in the form a(x) ;
Hence, Q(18) is a mathematical representation of the weight in pounds of a puppy after 17 months
Q(30) = 27.5 ; This means that the weight of puppy after 30 months will be 27.5 pounds. 27.5 is the result of working out the function Q at 30.
there are 18 pieces of dark chocolate and the ratio of dark and white is 3:2 so we can divide 18 by 3.
18/3 = 6.
This means the ratio of dark chocolate to white as a 1:1 ratio would be 6:6 so we can multiply 6 by 2 to give us the total amount of pieces of white chocolate.
6*2 = 12.
Therefore there are 12 white chocolate pieces.
Answer:
negative
Step-by-step explanation:
a positive divided by a negative is a negative
19x - 22 is you combine like terms!
Answer:
f(x) = 4/7x + 20/7
Step-by-step explanation:
If we were to graph this function, we would see that the two points would be, (-5, 0), and (2, 4). First, we have to find the slope, which is equal to:
<u>(first y-coordinate - the second y coordinate)</u>
(first x-coordinate - second x coordinate)
= <u>(0 - 4)</u>
(-5 - 2)
= -4/-7 = 4/7. now, we multiple -5 by 4/7 and get -20/7. we have to add 20/7.
Thus, the answer is f(x) = 4/7x + 20/7
