Answer:

11. -3 - (-8) = 5

12. -10 + (-25) = -35

13. -11 - (-10) = -1

14. 12 + (-5) = 7

15. -9 (9 + (-9) = 0)

Step-by-step explanation:

I don't really know how to explain it. For 11 I just found found the difference kind of. It's easier if you draw out a number line. 12 is self - explanatory, you just add the two negative numbers and it will be a negative. I look at 14 as just another minus equation.

Answer:

11. 5

12. -35

13. -1

14. 7

15. -9

Step-by-step explanation:

11. -3-(-8)

= -3 + 8 (double negative is positive)

= 8-3

= 5

12. -10 + (-25)

= -10 -25 (positive negative is negative)

= -35

13. -11 - (-10)

= -11 + 10

= -1

14. 12 + (-5)

= 12 - 5

= 7

15. 9 + x = 0

x = 0 - 9

x = -9

ANSWER QUICKLY!!!!!
Paul [167]

Answer:

1. The possible roots are ±1, ±2, ±3, ±6. These are the factors of the trailing constant (6) divided by the factors of the leading coefficient (1). When the leading coefficient is 1, the possible roots are the factors of the constant

2. The polynomial is easier to evaluate when it is written in Horner form:

 f(x) = ((x -4)x +1)x +6

To show that 2 is a zero, we want to find f(2):

 f(2) = ((2 -4)2 +1)2 +6 = (-4 +1)2 +6 = -6 +6 = 0

 f(2) = 0, so 2 is one of the zeros of this function

3.  Using synthetic division (attached) or polynomial long division, we can divide the given polynomial by (x-2) to find the remaining factors. This division gives (x^2 -2x -3), which can be factored as (x -3)(x +1), so the three actual roots are ...

 x = 2 (from above), x = 3, x = -1 (from our factorization)

4. In factored form, the polynomial can be written ...

 f(x) = (x +1)(x -2)(x -3)

The first factor was found from the fact that 2 was given as a zero of the function. For any zero "a", a factor of the polynomial is (x-a).

The remaining factors were found by factoring the quadratic trinomial that resulted from the division of f(x) by x-2. That trinomial is x^2 -2x -3.

There are a number of methods that can be used to factor x^2 -2x -3. Again, the rational root theorem can help. It suggests that ±1 and ±3 are possible roots.

How do I find B in y=mx+b?
mixas84 [53]
If you already have an equation, all you have to do is locate the slope and look after it. But if it's in a graph, it's where the line is crossing the y-axis.

An example of the equation would be

y=2x+3
y=mx+b
2 would be m which is slope
and 3 would be b which is the y-intercept

Which Two equations below are perpendicular?
UkoKoshka [18]

Answer: The answer is the second equation (y = 3x-4 and y = -1/3x - 2)

Step-by-step explanation:

This is because two lines are perpendicular when the slopes of the equations are negative reciprocals from each other.
