Answer:
16 cookies
Step-by-step explanation:
20/1.25=16
You take the total cost and divide it by the individule cost
Option A: y = 1/4x is the right answer
Step-by-step explanation:
The proportional relationship is defined as the increase/decrease in one quantity causes increase/decrease in other quantity.
The general form is:
y = kx
The proportional equations usually do not have any term that is added or subtracted.
comparing the given options with general form we can see that only one option is relatable to the general form of proportion.
Hence,
Option A: y = 1/4x is the right answer

Answer: Choice C</h3>
=============================================
Explanation:
Choices A, B and D are not true because of the negative y values. The result of an absolute value is never negative. So we can rule out choices A, B, and D. We have choice C as the only thing left, so this must be the answer.
-------------
Another way to see this is by plugging in each x value to see what y value comes out.
- If x = -2, then y = |5*x| = |5*(-2)| = |-10| = 10
- If x = -1, then y = |5*x| = |5*(-1)| = |-5| = 5
- If x = 0, then y = |5*x| = |5*0| = |0| = 0
- If x = 1, then y = |5*x| = |5*1| = |5| = 5
- If x = 2, then y = |5*x| = |5*2| = |10| = 10
The y outputs from top to bottom are: 10, 5, 0, 5, 10
This matches with what choice C shows.
now one denominator is x^2 + 8x + 15
if we factorise then (x +3)(x +5)
now in expressions which have like x+3 as denominator ...you multiply and divide them by x+5 and once u get denominator equal you can add numerator easily
Answer:
$0.407291667 per ounce
Step-by-step explanation: there are 16 ounces in a pound. 16 times 3 is 48.
in order to find the price per ounce, we need to divide the total price by the number of ounces
19.55/48 is 0.407291667
