Step-by-step explanation:
a function with a graph that is a non-vertical straight line, which can be represented by a linear equation in the form of y = mx + b
Answer:
10kg and 60 kg.
Step-by-step explanation:
Let the kid's mass be x kg, then the goat's mass is 6x.
x + 6x = 70
7x = 70
x = 10.
Answer: C) P(y) = 150(y – 15) – 125y
Step-by-step explanation:
Hi, to answer this question we have to write an equation:
Profit = revenue - cost
Cost: a watch store paid $125 per watch for a shipment of watches
Cost = 125 y
Where y is the number of watches in the shipment
Revenue: sold all but 15 watches from the shipment for $150 per watch
Revenue = 150(y-15)
Profit(y) = 150(y – 15) – 125y
So, the correct option is:
C) P(y) = 150(y – 15) – 125y

Answer:
1.)
interval over which the difference of the numbers of sales is increasing: (<u>4.9, 10)</u>
interval over which the difference of the numbers of sales is decreasing: <u>(0, 4.9)</u>
interval over which the difference of the numbers of sales is positive: <u>(-9, -3)</u>
interval over which the difference of the numbers of sales is negative: <u>(-3, 10)</u>
<u />
2.)
The team’s total number of sales is equal to the average number of sales at
<u>-9, -3, and 10 </u>months from when Jared began gathering data.
The team’s minimum number of sales this year occurred at approximately
<u>-28</u> months from when Jared began gathering data.
3.)
(x + 3)
(x + 9)
(x - 10)
4.)
f(x) = 0.05x^3 + 0.1x^2 - 4.65x - 13.5
5.)
a = 0.05
b = -9
c = -3
d = 10
