The sum and product of two linear functions are shown.
RoseWind [281]

The statements can be used to describe the original functions f(x) and g(x) are;  Option B

<h3>How to interpret function graphs?</h3>

Let the functions be

f(x) = ax + b

g(x) = cx + d

Their sum is;

j(x) = (a + c)x + b + d

Their product is;

k(x) = (ax + b)(cx + d)

From the graph, we see that;

f(x) = x + 6

g(x) = -2x² + 8

f'(x) = 1

g'(x) = -4x

What is the solution set of the equation<br> 3X=-6/1-X<br> for x # 1?
Irina-Kira [14]

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) .

PLEASE HELP <br> 10TH GRADE GEOMETRY
FromTheMoon [43]

Answer:

perimeter = 4 \sqrt{26}

Step-by-step explanation:

Using the distance formula

AB = \sqrt{(-4 - 1)^{2} + (3 - 4)^{2} }

     = \sqrt{(-5)^{2} + (-1)^{2}  }

     = \sqrt{25 + 1}

     = \sqrt{26}

The perimeter of a square is 4 times the length of one side.

So,  perimeter = 4 \sqrt{26}

1. f(6) if f(x) = 4x I know the answer I just need the explanation please thank you!
suter [353]
So when you have one of these, it’s just asking you so solve it as if x were 6 (as you see where the x in f(x) is replaced with a 6.

so you’d sub x for 6

giving you:

4 x (6)

which = 24

hope that makes sense :)
