Answer:
x = 0
Step-by-step explanation:
Let's divid both sides of the equation by 2 first, so we don't have as much work to do in the next step:
![4x-2y=6\\2x-y=3](https://tex.z-dn.net/?f=4x-2y%3D6%5C%5C2x-y%3D3)
Substituting -3 for y:
![2x-(-3)=3\\2x+3=3\\2x=0\\x=0](https://tex.z-dn.net/?f=2x-%28-3%29%3D3%5C%5C2x%2B3%3D3%5C%5C2x%3D0%5C%5Cx%3D0)
Answer:
B.
Step-by-step explanation:
x represents the amount of guests going to the birthday party, with the amount of money per guest being 12. You would multiply those two together, but as we do not know the total amount of guests, we keep it as a variable. 125 is the amount before the guests even know about the party, so therefore, you would need to use that equation.
Answer:
$34.77
Step-by-step explanation:
6,12,18,24,30,36,42,48,54,60,66,72,
The equation of the perpendicular line will be y = (4/3)x.
<h3>What is a linear equation?</h3>
A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
Then the equation of the perpendicular line will be given as
y = - (1 / m)x + c
The equation of line is y = -3/4 x + 1.
Then the equation of the perpendicular line will be
y = 4/3 x + c
The equation is passing through (9, 12), then we have
12 = 4/3 (9) + c
12 = 12 + c
c = 0
Then the equation of the perpendicular line will be y = (4/3)x.
