Answer:

I believe the answer is the system has one solution. Both lines have the same y-intercept. And the solution is the intersection of the 2 lines.

2x^2 - 7x - 6 = 0

$x1 = \frac{- b + \sqrt{ {b}^{2} - 4ac }}{2a}$
$x2 = \frac{- b - \sqrt{ {b}^{2} - 4ac }}{2a}$
where a=2
where b=-7
where c=-6

solve for x1 and x2

x1=4.21
x2=-0.71

-3x-2y=-1<br> 4x+6y=12<br><br> what’s all the steps and answer to this equation

abruzzese [7]

Answer:

x = -9/5

y = 16/5

Step-by-step explanation:

-3x-2y=-1 first you need to multiply the numerator by 3 so when adding

4x+6y=12 the y's cancel and you get a single variable

3(-3x-2y=-1) —> -9x - 6y = -3 then you add the like terms

4x+6y=12 —> 4x + 6y = 12

(-9x+4x) + (6y - 6y) = (-3 + 12)

-5x = 9 then you divide by -5

x = -9/5

then you plug this in to either equation

4(-9/5) + 6y = 12

-36/5 + 6y = 12 then you add 36/5 to both sides

6y = 96/5 then you divide by 6

y = 16/5

Note: Type out the correct classification for each graph.

1) First is an odd function because f(-x)=-f(x)
3) 3d is an even function because f(-x)=f(x)
2) 2d looks like sin function and it is also odd.
