Answer:
Discriminant is 60
Step-by-step explanation:
the discriminant of ![3x^2 + 6x = 2](https://tex.z-dn.net/?f=3x%5E2%20%2B%206x%20%3D%202)
To find discriminant , first we write the equation in the form of
![ax^2+bx+c=0](https://tex.z-dn.net/?f=ax%5E2%2Bbx%2Bc%3D0)
![3x^2 + 6x = 2](https://tex.z-dn.net/?f=3x%5E2%20%2B%206x%20%3D%202)
Subtract 2 on both sides
![3x^2 + 6x-2=0](https://tex.z-dn.net/?f=3x%5E2%20%2B%206x-2%3D0)
a=3, b=6, c=-2
Formula for discriminant is ![b^2-4ac](https://tex.z-dn.net/?f=b%5E2-4ac)
Plug in the values
![b^2-4ac=(6)^2-4(3)(-2)=60](https://tex.z-dn.net/?f=b%5E2-4ac%3D%286%29%5E2-4%283%29%28-2%29%3D60)
Discriminant is 60
Answer:
B
In the equation y=mx+b m is the slope of the line.
Therefore the coefficient in each of these equations is the slope.
A line with a perpendicular slope must have the inverse opposite of the actual line. For example if a line has a slope of 5, a perpendicular line to that line must have a slope of -1/5. If a line has a slope of 10, the perpendicular line has a slope of -1/10. If a line has a slope of 2 then the inverse opposite is -1/2 and that is the slope of the perpendicular line.
B is the only answer with the correct slope so B is the answer.
Step-by-step explanation:
Slope intercept form is y=m(x)+b
M is the slope to find it you do the first y value minus the second y value and do the same for x
-6-2. 3+1
You then divide the subtracted y values by the subtracted x values
-8/4
M=-2
To find the b you plug in one set of the coordinates
-6=-2(3)+b
-6=-6+b
b=0
So the equation is
Y=-2x
Answer:
24x+8+−10x+5
Step-by-step explanation:
Do distributive property.
4*6x=24x
4*2=8
5*2x=10x
5*-1=-5
So 24x+8+−10x+5 is your answer.
Answer:
Let the angles have measures 2x,3x,4x
Then 2x+3x+4x = 180
and the rest is easy
