Answer: -30
Step-by-step explanation:
6(-5)
The negative sign will still stay.
Hence, 6x -5
= -30
Feel free to ask any questions. I'd be glad to explain.
It would be smaller because 11/12 = 22/24
(i) To show that a piecewise function is continuous at a point, we need to show that the left hand and right hand limit "agree" with each other. In other words, we want:
Now, since we're given the constraints and the equation of each constraint, we notice that 6061^+ is a number that is slightly bigger than 6061. So we use the second equation. Do you see why?
In much the same way, 6061^- is a number that is slightly smaller than 6061. So we use the first equation. Again, do you see why? (Hint: look at the conditions on x for each equation).
So finally, computing each limit means just "plugging" 6061 into their respective equations. That is:
Since your limits match, we say that, at the point x = 6061, T(x) IS continuous.
(ii) Repeat the process above with x = 32473.
(iii) Find a point of discontinuity just means your right hand and left hand limits do not match -- I'm not an economist, so I may not be of much help with the latter part of the question!
Like terms have to have the same variables(and exponents on the variables).
So the like term would be

Answer:
1 apple costs $1.2
1 pear costs $1
Step-by-step explanation:
Represent Apples with A and Pears with P
For the person in my front, the expression is:
For me, the expression is
Hence, the system of equation is:
Solving for the values of A and P.
Substract equation (2) from (1)
<em>Hence, 1 pear costs $1</em>
Substitute 1 for P in
<em>Hence, 1 apple costs $1.2</em>
