Answer:
Discounted price = $160
Step-by-step explanation:
Let x be the discounted price of shoes.
Given:
A department store has a discount on shoes based on a percentage of the price.
and marked down on one pair of shoes is $80 to $64.
So, the discounted rate = 80 - 64 = 16
therefore, the percent of discount is.
% value 
% value 
% value 
% value 
% value 
% value = 20%
Find the price for a $200 pair of shoes after the same discount is applied.
So the discount is 20% and the discounted price of the shoe is 80% of $200.
% value 
80 


x = $160
Therefore, the discounted price of the shoe is $160.
answer : option C

Lets find the number of zeros by factoring

Group first two terms and last two terms

Factor out GCF from each group


Now we set each factor =0 and solve for x
0 = (x^2-8) and (x + 1)=0
and x = -1
and x= -1
So we have three real zeros
The function has three real zeros. The graph of the function intersects the x-axis at exactly three locations.

Answer:
Step-by-step explanation:
2,401 = 7^6 - 2x
2401 + 2x = 117649
2x = 117649 - 2401
2x = 115248
x = 115248 / 2
x = 57624
Answer:
The twentieth term is 50.
Step-by-step explanation:
The equation that describes the arithmetic sequence describes it's "general term", which means that all the numbers in that sequence must follow that equation. For instance, if we want to find the first term of the sequence we must make a = 1 and we have:
a1 = 3*1 - 10
a1 = -7
Therefore to find the twentieth term we need to make n equal to 20. This is done below:
a20 = 3*20 - 10
a20 = 60 - 10
a20 = 50
The twentieth term is 50.
