Answer:
Step-by-step explanation:
I've enclosed a graph to show you that there is one solution.
-4x + 3y = - 12
<u>- 2x + 3y = - 18</u><em><u> </u></em><em> </em>Subtract
-2x = 6 Divide by - 2
-2x/-2 = 6/-2
x = - 3
- 4x + 3y = - 12
-4(-3) + 3y = - 12
12 + 3y = - 12
3y = - 12 - 12
3y = - 24
3y/3 = - 24/3
y = - 8
Which is exactly what the graph shows.
You can tell immediately that this has 1 or more solutions just by looking at the number in front of x and y in each each equation.
It's always a good idea to graph a question like this one. Desmos is a pretty good tool to use if you don't have a graphing calculator.
The y's are the same so you are 1/2 way home in saying what you did.
The x's are different so that means you have at least 1 solution.
Answer:
Yes, but you have to write what the slope and y-intercept of the equation is as well.
Step-by-step explanation:
(Not sure if you wanted the full answer or just if you should graph it but I'm putting it here anyways :^P)
First convert the equation from standard form to slope-intercept form.
5x-3y=18 -> 5x-18-3y -> 5/3x-6=y
5/3x is the slope and 6 is the y-intercept!
Then graph the equation.
Im not sure if this is exactly what you asked because the grammar is weird but here Answer:
6
Step-by-step explanation:
12 divided by 2 is 6
