Answer:
(3, 6); (-3, 18)
Step-by-step explanation:
We equate the 2 expressions in x :-
x^2 - 2x + 3 = -2x + 12
x^2 - 2x + 2x + 3 - 12 = 0
x^2 - 9 = 0
(x - 3)(x + 3) = 0
So x = 3 or -3.
When x = 3, f(x) = -2(3) + 12 = 6.
When x = -3, f(x) = -2(-3) + 12 = 18.
1/a^3

Answer:

Step-by-step explanation:
Given:
Consecutive Terms: k-5, k+7, k+55
Required:
Determine the value of k
To do this, we make use of the concept of common ratio.
The common ratio (r) of a geometric sequence is:

In other words:

Where 1, 2 and 3 represents the terms of the progression/sequence
So:
becomes

Solve for k


17.50-14=3.50$
17.50 + 3 toppings = 20$ is the answer
