Answer:

(x+2) ^2 =11

Step-by-step explanation:

x^2+4x=7

To complete the square, take the coefficient of the x term, 4

Then divide by 2, 4/2 =2

Then square it 2^2 =4

Add that to both sides

x^2 +4x+4 = 7+4

The left hand side can be rewritten as (x+b/2) ^2 where b is the coefficient of the x term

(x+2) ^2 =11

Nuetrik [128]

Answer:

Not a solution.

Step-by-step explanation:

y = 5x + 9

-3 = 5(-2) + 9

-3 = -10 + 9

-3 ≠ -1

The point given is not on the line. It is NOT a solution to the equation.

Hope this helps.

What is k(-4) equal to? K:m => 7+m^2 K(-4) = [1]

Zarrin [17]

The function is defined as

$k:m\mapsto m^2+7$

This means that, taken an input m, the output is the input squared, plus 7.

So, if we take the input -4, we square it to get 16, and we add 7 to get 23.
