hey mate,
<=>
As we know that
then
<=> (x+4) = 0
<=> x = -4
so there is one solution x = -4
thanks
The answer is 8.6 units.
To solve this problem you use the distance formula.
Answer:
w = - 16.06 or w = 2.06
Step-by-step explanation:
Given
w² + 14w - 33 = 0 ( add 33 to both sides )
w² + 14w = 33
To complete the square
add ( half the coefficient of the w- term )² to both sides
w² + 2(7)w + 49 = 33 + 49, that is
(w + 7)² = 82 ( take the square root of both sides )
w + 7 = ± ( subtract 7 from both sides )
w = - 7 ± , that is
w = - 7 - ≈ - 16.06 or w = - 7 + ≈ 2.06
Answer:
Ram bought that motorcycle for Rs. 36000
Step-by-step explanation:
Given that:
Amount gained = 25%
Selling price of motorcycle = Rs. 45000
As 100% will be the original price, then 25% will be added into it.
125% will be the new percentage.
Let,
x be the original price of motorcycle.
125% of x = 45000
1.25x=45000
Dividing both sides by 1.25
x=36000
Hence,
Ram bought that motorcycle for Rs. 36000
