Answer:
{-11, -9, -7, -5, -3}
Step-by-step explanation:
Put each domain value into the function to find the corresponding range value. The range is the list of all of those values.
__
range = f(domain)
= 2{-2, -1, 0, 1, 2} -7 = {-4, -2, 0, 2, 4} -7
= {-11, -9, -7, -5, -3} . . . . . the range for the given domain
_____
If you have a lot of function values to find, a spreadsheet or calculator can be helpful.
Answer:
x = $3
y = $4
Step-by-step explanation:
We need to know the prices of gravel and peas. We can find the price by using equations and graphing them.
Let X be the price of the sand
Be and the price of pea gravel
In the first purchase we have:
In the second purchase we have
Both relations represent the equation of a line. In the graphic shown, these lines are drawn. In this case the interception between both lines represents the price of each product, and the solution of the problem. You can see that the lines intersect at point (3 4). This means that the price of each bag of sand is $ 3, and the price of a bag of pea gravel is $ 4.
