Step-by-step explanation:
<u>So the domain of f(x) := tanx is all real numbers except x = π 2 + kπ, k an integer.</u>
It is similar to an equation
-3x-6<-5x-2
-3x+5x<-2+6
2x<4
x<4/2
x<2
* when solving inequality problems you need to switch signs when you divide a side by a negative number.
Ex.
-3x-6<-5x-2
-6+2<-5x+3x
-4<-2x
When you divide -4 by -2, switch the lesser sign to greater sign.
-4/-2>x
2>x
Which gives you the same result either way.
x<2
Answer:
2, 70
Step-by-step explanation:
It is given that :
At Nolan's Car rentals, if a customer rents a car, he or she has to pay $60 for the car for the first day and more $ 5 for every additional days.
Therefore this gives the equation :
y = 5x +60 ..........(1)
At Westford car rental, the price of the car for first day is $ 50 and additional $10 for every additional day.
So the equation will be :
y = 10x + 50.......(2)
Solving (1) and (2), we get
5x + 60 = 10x + 50
⇒ 60 - 50 = 10x - 5x
⇒ 10 = 5x
∴ x = 2
Now putting the value of x = 2 in equation (1), we get
y = 5x +60
y = 5(2) +60
y = 70
Therefore, (x, y) = (2, 70)
