Solve for 2x^2-4x+5=6
Softa [21]
To solve for a variable, you need to get it (x) by itself.

2x² - 4x + 5 = 6   Subtract 6 from both sides
2x² - 4x - 1 = 0   Plug this into the Quadratic Formula

a = 2 , b = -4 , c = -1
x = \frac{-b \pm  \sqrt{b^2 - 4ac} }{2a}   Plug in your values
x = \frac{-(-4) \pm \sqrt{(-4)^2 - 4(2)(-1)} }{2(2)}   Simplify
x = \frac{4 \pm \sqrt{16 + 8} }{4}   Simplify
x = \frac{4 \pm 2\sqrt{6} }{4}   Simplify by removing a 2 from every term
x = \frac{2 \pm \sqrt{6} }{2}   Simplify by taking the fraction apart
x = \frac{2}{2}  \pm  \frac{ \sqrt{6} }{2}   Change \frac{2}{2} to 1
x = 1 \pm  \frac{ \sqrt{6} }{2}   Simplify \frac{ \sqrt{6} }{2} to \sqrt{ \frac{3}{2} }
x = 1 \pm \sqrt{ \frac{3}{2} }

Exit Ticket: At noon, a tank has a water depth of 9 in. After 3 hours, the depth was 8 inches. At 6pm, the depth was 7 inches. W
OLEGan [10]

Answer:

Step-by-step explanation:

The  straight line equation is:

y = m*x  + b     Where m is the slope of the line and b the intercept with   y-axis, in our case y is the depth of the tank and x (time in lapsus of 3 hours).

The slope m  =  ( y₂ -  y₁ ) / (x₂ - x₁)

We have point  A ( 3 , 8 )  and point  B ( 6 , 7 )

m  = ( 6 - 3 ) / (7 - 8 )  m = -3

We see that  each 3 hours time-depth decreases  1 in.

Then   to find the depth at the beginning of x-axis

At  noon     12   tank was  9 inches, three hours before at 9 in the morning the depth was 10 inches and:

9  in the morning   10

6  in the morning   11

3  in the midnight   12

12 in the night         13

Then 13 is the intercept with y-axis

then the equation is:

h = - 3*x + 13

Note x is time in lapsus  of 3 hours

Please walk me through this​
FinnZ [79.3K]

Answer:

X is 160. because you can add all the value of x. But first substrate 540 with 100 which is 440. then 1/2x + 1/2x+ (x-15) + (x-25) which is further simplified as x + 2x - 40. then it's further simplified as 3x - 40 = 440. then add 40 with 440 which is 480 then divide it by 3 which is 160. therefore X= 160.
