It is: 3x-11
we have to remove the unnecessary parentheses then we have to expand: x-4+2x-7
Finally we collect the like terms and calculate
that’s why the answer is 3x-11

Answer:

3x - 11

Step-by-step explanation:

( x - 4 ) + ( 2x − 7 )

*it's better to take away the parenthesis

x - 4 + 2x - 7

Combine like terms

( x with 2x, and -4 with -7)

3x - 11

And you cannot simplify it anymore

Hope this helped!

Is (2, 2) a solution of y < 4x – 6?
Roman55 [17]

Answer:

No

Step-by-step explanation:

To see if (2,2) is a solution, substitute them into the inequality and see if it is true.

2 is our x value, and 2 is also our y value

y < 4x – 6

2< 4(2)– 6

2 < 8 – 6

2 < 2

This statement is false. 2 is not less than 2, so (2,2) is not a solution to this equation.

beks73 [17]

Answer:

Minimum: (2,4)

Step-by-step explanation:

h(x)=3(x^{2}-4x)+16

=3(x^{2}-4x+4-4)+16   (- For the balance of equation, and attention 1)

=3(x-2)^{2}-3*4+16

=3(x-2)^{2}+4

<h3>Attention:</h3>

1. (a-b)^{2}=a^{2}  -2ab+b^{2}

2. The formula for the vertex form is y = a(x-h)^{2}+k, the vertex is (h,k)
