Answer:
9 / 4
Step-by-step explanation:
The slope of line V can be found using the formula for slope: (y2 - y1) / (x2 - x1).
(y2 - y1) / (x2 - x1)
(13 - 9) / (1 - 10)
(4) / (-9)
Two slopes are perpendicular when the values are reciprocals. The slope of line V is 4 / (-9). The reciprocal of this is: 9 / 4.
Expanded form is like this 300 plus 20 plus 7 plus .40 plus .6
Answer:
(x - 5)(x + 4)
Step-by-step explanation:
x^2 − x − 20
- 20 = -5 * 4
and
- 5 + 4 = -1
So
x^2 − x − 20 = (x - 5)(x + 4)
Hey there! :D
Add the expression's together.
3x+y=27
-3x+4y= -42
3x+(-3x)= 0
y+4y=5y
27+(-42)= -15
5y=-15
Divide both sides by 5.
y=-3
Now, find x.
3x+y=27
3x-3= 27
3x=30
x=10
The solution is (10,-3).
I hope this helps!
