B
Step-by-step explanation:
Quadratic graphs are pretty weird. If it says (x-3)^2 is means x will shift to the right. It shifts to the left, so it is (x+2)^2, and goes down 3, so
(x+2)^2 -- 3
The solution set of the equation 3X=-6/1-X for x # 1 is {-2,1)
3x = -6/(1-x)
3x(1-x) = -6
3x – 3x2 = -6
Taking 3 as common from both sides
x –x2 = -2
x2 – x +2 =0
Using factorisation method we will get two factors
Factoring quadratics is a method of expressing the quadratic equation ax2 + bx + c = 0 as a product of its linear factors as (x - k)(x - h), where h, k are the roots of the quadratic equation ax2 + bx + c = 0. This method is also is called the method of factorization of quadratic equations. Factorization of quadratic equations can be done using different methods such as splitting the middle term, using the quadratic formula, completing the squares, etc.
( x – 2)(x+1)=0
So, x = 2 , -1
Now, when x ≠ 1
The solution of the equation will vary from {-2,1) .

Answer: 7.4
Step-by-step explanation:
3x + 13 = 19
3x = 6
x = 2
Now substitute value of 'x' in the second equation:
2(2) + 1.2(2) + 1
= 4 + 2.4 + 1
= 5 + 2.4
= 7.4
