Answer:
The correct answer would be 4. Explanation below
Step-by-step explanation:
-6x-11x = 68
-6x-11x = -17x
-17x = 68
68/-17 = 4
Hope this helps!

Not only can it determine the gcf of 36 and 72, but also that of three or more integers including thirty-six and seventy-two for example. Keep reading to learn everything about the gcf (36,72) and the terms related to it. kmd</span>
Answer:
Since the independent variable x is not the exponent, 
does not represent an exponential function.
Step-by-step explanation:
The general expression of an exponential function is 
, where a > 0 and a ≠ 1
Now the given function is ..... (1)
So, we can say that the function f(x) = y is not an exponential function as x is not in power of any constant.
Therefore, since the independent variable x is not the exponent, does not represent an exponential function. (Answer)
Answer:
slope = 0
Step-by-step explanation:
The line with equation x = - 3 is a vertical line parallel to the y- axis
A perpendicular line is therefore a horizontal line parallel to the x- axis
The slope of the x- axis is zero, hence the slope of the horizontal line is
slope = 0
Answer:
2x^2 = 6x - 5.
-x^2 - 10x = 34.
These have only complex roots/
Step-by-step explanation:
3x^2 - 5x = -8
3x^2 - 5x + 8 = 0
There are complex roots if the discriminant 9b^2 - 4ac) is negative.
Here the discriminant D = (-5)^2 - 4*-5*8 = 25 + 160
This is positive so the roots are real.
2x^2 = 6x - 5
2x^2 - 6x + 5 = 0
D = (-6)^2 - 4*2*5 = 36 - 40 = -4
So this has no real roots only complex ones.
12x = 9x^2 + 4
9x^2 - 12x + 4 = 0
D = (-12)^2 - 4*9 * 4 = 144 - 144 = 0.
- Real roots.
-x^2 - 10x = 34
x^2 + 10x + 34 = 0
D = (10)^2 - 4*1*34 = 100 - 136 = -36.
No real roots = only complex roots.
