Answer:
the value of output is 29
Step-by-step explanation:
the output variable y is 12 less then the input variable x.
Input variable is x, output variable is y
output values = input variable - 12
now plug in the variable in the equation
output values = input variable - 12
Given the input value is 41
Substitute 41 for x
the value of output is 29
Answer:
The correct answer is - 17.
Step-by-step explanation:
Given:
total students = 219
in chemistry = 112
in physics = 45
not enrolled in either of these = 79
solution:
The number of students in both classes can be calculated by
P ( A or B) = P (A) + P (B) - P (A and B)
then putting and solving the given vaues in formula
=> (219-79) = 112+45-x
=> 140 = 157 -x
=> 17 = x
Answer:
145
Step-by-step explanation:
Because what you want to do is add 260 to 182 then subtract from 587. I hope that helped! :)
X-3y=12
3y=x-12
y=1/3x-4
parallel means same gradient, which is 1/3.
Use formula y-y1=m(x-x1), m=gradient and y1 is y coordinate of point and x1 is x coordinate of point.
y-4=1/3[x-(-3)]
y-4=x/3+1
y=x/3+5

First of all, you need to know that profit is the difference between selling price and cost price. In this problem, profit is equal to the markup. Total profit is equal to the profit on each car multiplied by the number of cars sold.
The profit on each car is 2000 -400n, where n is defined in the problem statement as the number of markdowns (of $400).
The number of cars sold is 20 +6n. (Starting at 20, increasing by 6 for every markdown.)
The total monthly profit is the product of these binomials.
.. P(n) = (2000 -400n)*(20 +6n)
.. P(n) = -2400n^2 +4000n +40,000 . . . . . . selection C

Matching functions to data points is often just a matter of trying them to see which fits. The first two function both match points (0, 2) and (1, 6). Functions C and D fail to match (1, 6).
Only the second function matches (2, 18).
The appropriate choice is
.. B. y = 2(3)^x
