Answer:im here for you!! the answer should be c if im correct its been 3 weeks since i do this please correct me if im wrong
Step-by-step explanation:
First, solve 10x + y = -20 for y: y = -20 - 10x
Next, substitute -20 -10x for y in the second equation:
-20 - 10x = 2x^2 - 4x - 16.
Rearranging, 2x^2 + 6x + 4 = 0
Simplifying, x^2 + 3x + 2 = 0
The roots of this poly eqn are -1 and -2. Therefore, x = -1 and x = -2.
One by one, subst. these x-values into y = -20 - 10x to find the corresponding y-values.
Your answers should look like this: (-1, y) and (-2, y) (different values for y).

Step-by-step explanation:
Aug
15 = 1 26 = 23.04 Total $737.28 that's a great deal
16 = 2 27 = 46.08
17 = 4 28 = 92.16
18 = 8 29 = 184.32
19 = 16 30 = 368.64
20 = 36 31 = 737.28
21 = 72
22 = 1.44
23 = 2.88
24 = 5.76
25 = 11.52
The answer is $4419.76
A = P (1 + r/n)^nt
Therefore,
A = 4000 (1 + 0.05/52)^52 x 2
A = 4000 (1.00096)^104
A = 4000 (1.1049)
A= 4419.76
Hope that helps!
(I'll take brainliest thank you ;))
Any of the given 5 letters can be at the start of the code.
Total choices = 5
We want the code to start with A
Choices in favor = 1
Probability = favorable/total = 1/5 = 0.20
