For this case we have the following system of equations:
Equating the equations we have:
Adding 3x to both sides of the equation:
Subtracting 9 from both sides of the equation:
Dividing between -3 on both sides of the equation:
We look for the value of "and":
Thus, the solution of the system is (2, -3)
Answer:
(2, -3)
Cancel equal terms on both sides of inequality
7-3x < 13
move constant to the right side and change its sign
-3x<13-7
subtract the numbers
-3x<6
divide both sides of inequality by -3 and flip the inequality sign
answer is: x>-2
Answer:
Y=-1/2x+4
Step-by-step explanation:
-The slope is -1/2 so you just plug it in where the slope would go with an x in front
-all you need now is your y-intercept which can be found by plugging in the provided info to your basic form y=mx+b
-You can take the provided point at (10,-1) and work out what the intercepts is
-1=-1/2(10)-b
-1=-5-b
4=b
This is going to be an long answer, so I'm putting the answer first. y=3x-7
First, you have to find the equation of the line given. You can use point slope form for that. You can see that the slope is -1/3, and it goes through (2,2). So, the equation would be
y-2=-1/3(x-2)
Which simplifies to
y=-1/3x+8/3
Now, we can get on to finding the actual answer. The slope of a line perpendicular would be the negative reciprocal of the original slope. That just means you flip it and multiply it by -1. So, the slope of the new line is 3. Now you can use point slope form again and make an equation, which is
y+1=3(x-2)
Which simplifies to
y=3x-7
Please don't ask me why the slope is the negative reciprocal, or how they came up with the formula for the point slope form. I DON'T KNOW. If you want to know so bad you would give up chick-fil-A for the rest of your life, there's always google.
