See in the attached file

<h2>Explanation:</h2>

In this case, we have the following linear function written in Standard form:

3x-y = 1

But we can write it in slope intercept form:

3x-y = 1 \\ \\ \\ Add \ -3x \ to \ both \ sides: \\ \\ 3x-y-3x = 1-3x \\ \\ -y=-3x+1 \\ \\ \\ Multiply \ by \ -1: \\ \\ y=3x-1

For the domain D: {-3, -1, 0, 4}, that is, x takes these values, we have the following y-values:

x=-3 \\ \\ y=3(-3)-1=-10 \\ \\ \\ x=-1 \\ \\ y=3(-1)-1=-4 \\ \\ \\ x=0 \\ \\ y=3(0)-1=-1 \\ \\ \\ x=4 \\ \\ y=3(4)-1=11

By using graphing tools we can graph the points:

(-3,-10) \\ \\ (-1,-4) \\ \\ (0,-1) \\ \\ (4,11)

The graph is shown below.

Factorise: a squared +8a -20
Vaselesa [24]
Factor out the 4 in both equations
8a^2-20^2=(2^2 times a^2 times 2)-(2^2 times 5)
therefor it is also equal to
(2a)^2 times 2-(2^2 times 5)
we can force it into a difference of 2 perfect squares which is a^2-b^2=(a-b)(a+b)
(2a√2)^2-(2√5)^2=((2a√2)-(2√5))((2a√2)+(2√5))

What is the value of X plz help
Tema [17]

Answer:

x = 16

Step-by-step explanation:

(5x + 12)° + (6x - 8)° = 180°

(5x + 12 + 6x - 8)° = 180°

(11x + 4)° = 180°

11x + 4 = 180

11x = 180- 4

11x = 176

x = 176/11

x = 16

A(n - 3) +8= bn for n please help me
Papessa [141]

Given equation: A(n - 3) +8= bn.

Solution: On the left side of the equation we have A(n-3).

We don't have any sign in between A and parenthesis (n-3).

So, we need to multiply A and (n-3).

We need to apply distributive property to multiply A and (n-3).

Distributing A over (n-3), we get

A(n-3) = A*n - 3*A = An -3A.

Substituting this value in original equation,

An -3A +8= bn.

We need to solve it for n, so we get n terms on a side.

We have An on left side, we need to get rid n from left side.

Subtracting An from both sides, we get

An -3A +8-An= bn-An.

-3A +8 = bn - An.

We can see n is a common factor on rigth side in bn-an.

Factoring out n on right side from bn-an.

-3A +8 = (b - A)n.

Dividing both sides by (b-A),

\frac{(-3A+8)}{(b-A)} = \frac{(b-A)n}{(b-A)}

On right (b-A) paranthiss cancelled and we get n on right side.

\frac{(-3A+8)}{(b-A)} =n   Final answer.

So, that would be our final answer

n = (-3A+8)/(b-A)
