Yes as that is the function notation in play. a function of x.
Answer:
This is NOT a function. Because if you used the vertical line test it would hit that line 2 times.
Step-by-step explanation:
Answer:
The answer is 22.
Step-by-step explanation:
Just well use a calculator. If you don't have that then use PEMDAS. Hope it helps.
Answer:
k=|14+x|-5
Step-by-step explanation:
just rewrite the equation as k=|14+x|-5
Answer:
25
Step-by-step explanation:
When we write expressions for the total cost of each field visit and set them equal, we find the solution to be the ratio of the difference in fixed cost to the difference in variable cost.
y = 75 +7x . . . . . cost for x students to visit the science center
y = 50 +8x . . . . cost for x students to visit the natural history museum
__
Subtracting the first equation from the second, we get ...
0 = -25 +x
25 = x . . . . . add 25; the number of students such that costs are equal
The cost will be the same either place for 25 students.
__
<em>Additional comment</em>
Here, the fixed cost difference is 75-50=25, and the variable cost difference is 8-7=1. The ratio of these costs is ...
$25/($1 /student) = 25 students.
This relationship only holds when the higher fixed cost is associated with the lower variable cost. Charges are such that one place caters to larger numbers of students (science center), and one prefers fewer students (natural history museum).
