Answer:
B:3(x-1)+2x=3(x-1)+2
Step-by-step explanation:
Aanya wrote the four equations that are shown below.
We need to check each equation and see which equations have same coefficient of x terms on both sides of equation.
A: 6x-8=4(x-2)+2x
Distribute 4 inside the parenthesis
6x-8=4x- 8+2x
We know 4x + 2x is 6x. So, both sides we have 6x. Hence no solution for this equation.
B:3(x-1)+2x=3(x-1)+2
Distribute 3 inside the parenthesis
3x - 3 + 2x = 3x - 3 + 2
5x - 3 = 3x- 3 + 2
Coefficient of x are not same on both sides. So this equation has exactly one solution.
C:7x+2-x=6(x+2)
Distribute 6 inside the parenthesis
6x + 2= 6x + 12
Both sides we have 6x. Hence no solution for this equation.
D:4(x+3)+x=5(x+1)+7
Distribute 4 and 5 inside the parenthesis
5x + 12= 5x + 5+ 12
Both sides we have 5x. Hence no solution for this equation.
<span>Which one is closer to 41/50, 9/11 or 10/11
=> Let’s find the value of the two given choices to be able to fin which one
is closer to 41/50
=> 9/11 convert this to decimal number
=> 9 divide by 11
=> 0.82
=> 10/11 convert in decimals
=> 10 divide by 11
=> 0.91
Now, we have the value of both numbers, let’s find the value of 41/50
=> 41/50
=> 41 divided by 50
=> 0.82
Thus, the closer number to 41/50 is the 9/11 because they both have 0.82
decimal value.

Answer:
B. -1
Step-by-step explanation:
If we have a parabola whose equation is:
The line of symmetry is calculated as:
Now, we have the equation 
and the line of symmetry is 
Where:
So, we can replace 
by -4 and 
by -2 and solve for 
using the following equation as:
It means that the equation of the parabola is equal to:
