Answer:
It is a GP.
Step-by-step explanation:
a = 3
r = 2
a(n) term = ar^n
As it increases as multiples, it is a geometric progression or a GP.
Answer:
a. Negative discriminant: above
b. Positive discriminant: below
c. Discriminant is zero: on
Step-by-step explanation:
If the discriminant is negative, then there are no real zeros. We have an upward-facing parabola, then the vertex is located above the x-axis
If the discriminant is positive, then there are two different real zeros. We have an upward-facing parabola, then the vertex is located below the x-axis
If the discriminant is zero, then there is one zero. We have an upward-facing parabola, then the vertex is located on the x-axis

Define x :
--------------------------------------------------------------
Let the dryer be x.
Dryer = x
Washer = x -53
--------------------------------------------------------------
Construct Equation :
--------------------------------------------------------------
The washer and the dryer cost $847
⇒ x + x - 53 = 847
--------------------------------------------------------------
Solve x :
--------------------------------------------------------------
x + x - 53 = 847
2x - 53 = 847
2x = 847 + 53
2x = 900
x = 450
--------------------------------------------------------------
Find cost of dryer and washer :
--------------------------------------------------------------
Dryer = x = $450
Washer = x = 450 - 53 = 397
--------------------------------------------------------------
Answer: Dryer = $450
