Answer:
when you distribute you will get -3g+6 because a negative times a negative is a positive.
Step-by-step explanation:
hope this helps
A^2 + b^2 = c^2....where a and b are the legs, c is the hypotenuse
3^2 + b^2 = 7^2
9 + b^2 = 49
b^2 = 49 - 9
b^2 = 40.....take sqrt of both sides, eliminating the ^2
b = square root of 40 <==
The domain of a graph of a function is x ∈ [-8, 9] and the range of a graph of a function will be y ∈ [7, 0]
<h3>What is a function?</h3>
It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a graph of a function shown in the picture.
As we can see in the graph there are two bold dots are shown which represents at these points the function value exist.
At x = -8, y = 7
At x = 9, y = 6
At x = -3, y = 0
The domain of a function is x ∈ [-8, 9]
The range of a function is y ∈ [7, 0]
Thus, the domain of a graph of a function is x ∈ [-8, 9] and the range of a graph of a function will be y ∈ [7, 0]

Answer:
x + 3y + 9 = 0
Step-by-step explanation:
y=3x + 2
Coefficient of x = 3
Gradient (m) of line y= 3x + 2 is 3
Since the line passing through point
(3,-4) is perpendicular to line y=3x + 2
hence gradient (m) of the line is -1/3;
And hence it equation is given as;
y - y1 = m(x - x1)
y - (-4) = -1/3(x - 3)
multiplying through by 3;
3 × y + 3 × 4 = 3 × -1/3(x - 3)
3y + 12 = -1(x - 3)
3y + 12 = -x + 3
x + 3y + 12 - 3 = 0
x + 3y + 9 = 0
