Step-by-step explanation:
To simplify recall exponent rules:
1. An exponent is only a short cut for multiplication. It simplifies how we write the expression.
2. When we multiply terms with the same bases, we add exponents.
3. When we divide terms with the same bases, we subtract exponents.
4. When we have a base to the exponent of 0, it is 1.
5. A negative exponent creates a fraction.
6. When we raise an exponent to an exponent, we multiply exponents.
7. When we have exponents with parenthesis, we apply it to everything in the parenthesis.
We will use these rules to simplify.
Use rule #3 to simplify inside the parenthesis first.

Now simplify the exponent of 4 using rule 6.

Answer:
Third graph in the photo
Step-by-step explanation:
x^2+3x-4 can be factored as (x+4)(x-1). When y=0, x must be -4 or 1 to satisfy the equations, and thus the roots of the graph are at x=-4 and x=1. When x=0, y=(4)(-1)=-4. The only graph that satisfies both of these requirements is the third/last one.
Y = |x - 21| represents an absolute value function.
Answer:
- Equal midpoints of AC and BC.
- The product of the slopes of the diagonals AC and DB is -1.
Step-by-step explanation:
1. Plot the given points, as you can see in the graph attached.
2. Calculate the midpoint of AC and DB:

Therefore, the midpoint of AC and DB are equal.
3. Calculte the slope of the diagonals AC and DB:

4. Multiply the slopes of the diagonals:
(AC and DB are perpendicular)
