Answer:

y²+6y+9

Step-by-step explanation:

Use FOIL(First, inner, outer, last) to distribute the (y+4)² to get to y²+8y+16. You will then distribute in -2(y+4) to get -2y-8. You will then combine like terms, adding in the +1, to get to your answer.

What is the axis of symmetry for f(x) = −5x2 − 20x − 10

Tasya [4]

For this case we have the following function:
 $f(x) = -5x^2 - 20x - 10
$
 To find the axis of symmetry, the first thing to do is to derive the function.
We have then:
 $f '(x) = -10x - 20 
$
 Equaling zero we have:
 $-10x - 20 = 0 
$
 We clear the value of x.
We have then:
 $-10x = 20 

x = -20/10 

x = -2 
$
 Answer:
The axis of symmetry is given by:
x = -2

Solve the following system of equations. If there is no solution, write DNE in each coordinate of the

Rainbow [258]

Answer:

1) solution is y = -7

2.) DNE

3.) Solution is y = -2

Step-by-step explanation:

1.) 2+3 = y + 12

Add the LHS and make y the subject of formula

5 = y + 12

Y = 5 - 12

Y = - 7

The solution of the equation is - 7

2.) 2 + 13 = 1 +8

Since there is no unknown variable and the sum of the numbers in the left hand side ( LHS ) is not equal to the sum of the numbers in the right hand side ( RHS ), it will be concluded that there is no solution in the equation.

3.) y - 7 = 2 - 11

Sum the RHS and make y the subject of formula

Y - 7 = -9

Y = -9 + 7

Y = -2

The solution of the equation is -2
