Answer:
The value of x for the expression is 2
Step-by-step explanation:
Given algebraic expression as :
(4 + 6 x ) =
x +
( x + 9 )
Now, solving the given expression
Or, × 4 +
× 6 x =
x +
x +
× 9
Or, +
× x =
x +
x +
or, 2 + 3 × x = +
+ 6
or, 2 + 3 × x = + 6
or, 2 + 3 × x = + 6
Or, 2 + 3 × x = x + 6
or, 3 x - x = 6 - 2
Or, 2 x = 4
∴ x =
I.e x = 2
Hence The value of x for the expression is 2 Answer
Hello!
x² + 6x + 1 = x - 3
Bring all terms to one side by subtracting x and adding 3:
x² + 6x - x + 1 + 3 = x - x - 3 + 3
x² + 5x + 4 = 0
Factor:
(x + 4)(x + 1) = 0
Set each factor to 0:
x + 4 = 0
x = -4
x + 1 = 0
x = -1
Answer:
Time taken by A = 16 seconds
Time taken by B = 12 seconds
Step-by-step explanation:
Given:
Two elevator and their respective time to reach certain height.
Here time is function of height.
Time taken by elevator A = 0.8(h)+16
Time taken by elevator B = -0.8(h)+12
We have to find the time taken by the elevator to reach ground level.
Accordingly:
We know that ground level the height will be zero meaning that (h=0).
Plugging the h values in the equation we can find the time taken by both the elevators to reach zero height that is the ground level.
⇒ ⇒
⇒ ⇒
⇒ sec ⇒
sec
So,
Time taken by elevator A and elevator B to reach the ground is 16 seconds and 12 seconds respectively.
