Answer:
x= +- 4/3
Step-by-step explanation:
(3x+4)(3x-4)=0
make each equation set to 0 and solve
3x+4=0
subtract 4 from both sides
3x=-4
divide both sides by 3
x=-4/3
3x-4=0
add 4 to both sides
3x=4
divide both sides by 3
x=4/3
Answer:
So these two equation can be related by identity 
Step-by-step explanation:
We have given equation 
And
We know the algebraic identity 
From this identity
can be written as (x+1) (x-1)
And using same identity 
can be written as 
So these two equation can be related by identity
<span>To explain how these values are related, take the second value (625) and multiply it by 1/100, or in decimal form, 0.01. This is the equivalent of moving the decimal point two spaces to the left, which will give a result of 6.25. (625 * 0.01 = 6.25). This shows that the two values are 100 times different than each other.</span>
<u>Answer</u>
20%
<u>Explanation</u>
let the cost of tie = x
Then cost of a pair of pants = (100+50)%x
= 150%x
= 1.5x
The cost of shirt = (100+25)%x
= 125%x
= 1.25x
(1.5x - 1.25x)/1.25x × 100
0.25x/1.25x × 100
0.2 × 100 = 20%
Answer: They are inverses of each other.
Explanation:
f(x) = -x+5
f(g(x)) = -(g(x)) + 5
f(g(x)) = -(-x+5) + 5
f(g(x)) = x - 5 + 5
f(g(x)) = x
The steps to show that g(f(x)) = x are identical to what is shown above. This is because both f(x) and g(x) are the same.
Since f(g(x)) = x and g(f(x)) = x are true, this means the functions are inverses of each other.
