Answer:
Make it as simple as possible, and use 1 and −1 .
1×1×1×1×1×−1×−1×−1×−1×−1=
15×(−1)2×(−1)2×−1=
1×1×1×−1=
−1.
So, the sign will be negative.
Another way of thinking about this is to not even think about the positive integers, as they won’t affect the sign. A positive integer times a positive integer is still a positive integer; a negative integer times a positive integer is still a negative integer.
So, you have five negative integers. Think of it like two negative integers, two more negative integers, and a single negative integer. Since two negative integers form a positive integer, you now have a positive, positive, and negative integer. This forms a negative sign.
Answer:
D. -4
Step-by-step explanation:
The formula for calculating the slope of his indifference curve at his current consumption is expressed as:
M = -∆y/∆x
∆y is the change in y axis
∆x is the change in x axis
Since apples are put in the horizontal axis, ∆x = 20
Since banana are on the y axis, then ∆y = 80
Substituting the given values into the formula
M = -80/20
M = -8/2
M = -4
Hence the slope of his indifference curve at his current consumption is -4.
Option D is correct.

Answer:
C. 46 degrees
Step-by-step explanation:
In a rotation all angles and side lengths are preserved so the angle measure will be the same in both the image and pre-image.
