Answer:
(x-5) (x+4)
Step-by-step explanation:
x^2 - X-20
Factor
What two numbers multiply to -20 and add to -1
-5*4 = -20
-5+4 = -1
(x-5) (x+4)
Answer:
1/16
Step-by-step explanation:
Answer:
4) slope= 0
5) 
Step-by-step explanation:
4) Slope
= 0
The slope is zero as the line is a horizontal line (since both points have the same y-coordinate of 10).
5) Slope
Since you have taken (x₁, y₁) to be (9, 4), the value of x₁ should be 9 instead of 2.
<span>Simplifying
x + -1.4 = 7.82
Reorder the terms:
-1.4 + x = 7.82
Solving
-1.4 + x = 7.82
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '1.4' to each side of the equation.
-1.4 + 1.4 + x = 7.82 + 1.4
Combine like terms: -1.4 + 1.4 = 0.0
0.0 + x = 7.82 + 1.4
x = 7.82 + 1.4
Combine like terms: 7.82 + 1.4 = 9.22
x = 9.22
Simplifying
x = 9.22</span>
