Step-by-step explanation:
3х + 2y = 14
3х - 2y = 10
6x=24
x=4
3×4+2y=14
12+2y=14
2y=14-12
2y=2
y=1

Hello if I know the answers to your math questions I'll answer if there already posted I'll check your profile if not please post them thank you!
Basically you just have to do either $18/4 or $27/6 which gets you to 4.5 which is the unit rate
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]

Hello,
Let's assume a the hypotenuse
b/a=sin 30°==>b=a/2
c/a=cos 30°==>c=√3 / 2 *a
(√3/2 a, a/2,a) are the sides of the triangle.
