For this case what you should be aware of is that the root does not take negative values.
We then have to be aware of the domain of the function.
Note: see attached graphic.
Ansewer the domain of the graph is all real number less than or equal to 0 option 3
The figure is a parallelogram so the facing sides have equal size which means :
DE = GF & DG = EF
-------------------------------------------------------------
DE = 3x - 1 , GF = 2x + 11
DE = GF ==》 3x - 1 = 2x + 11
subtract sides minus 2x
==》- 2x + 3x - 1 = - 2x + 2x + 11
collect like terms
==》 x - 1 = 11
add sides 1
==》 x - 1 + 1 = 11 + 1
==》 x = 12
-------------------------------------------------------------
As we found : DG = EF
DG = 2x - 3 So EF = 2x - 3
To find the size of EF, we need to put the value of x (which we found above) instead x.
EF = 2 × ( 12 ) - 3 ==》 EF = 24 - 3
==》 EF = 21
And we're done...
Answer:
x=-2
Step-by-step explanation:
6 - 2x = -4x + 2
When moving one number to the other side of the equal sign, change it from either negative to positive or positive to negative
4x - 2x = -6 + 2
add/subtract
2x = -4
divide each side by 2
x = -2

Answer:
Using the quadratic formula to solve 5x = 6x^2 – 3, what are the values of x?
5x = 6x^2 – 3
Subtract 5x from both sides:
0 = 6x^2 – 5x – 3
a = 6, b = -5, c = -3
x = (-b ± √(b^2 - 4ac))/(2a)
x = (-(-5) ± √((-5)^2 - 4(6)(-3)))/(2(6))
x = (5 ± √(25 + 72))/12
x = (5 ± √(97))/12
