Answer:
![a = \frac{-1}{3}.](https://tex.z-dn.net/?f=a%20%3D%20%5Cfrac%7B-1%7D%7B3%7D.)
Step-by-step explanation:
The equation of line in the form .
y = mx + c
Where m is the slope and c is the y- intercept .
As given
The lines y=3x-1 and y=ax+2 are perpendicular .
Here 3 is slope for equation of line y=3x-1 and a is slope for equation of line
y=ax+2 .
Now by using properties of the perpendicular lines property .
When two lines are perpendicular than slope of one line is negative reciprocal of the other line .
Thus
![a = \frac{-1}{3}](https://tex.z-dn.net/?f=a%20%3D%20%5Cfrac%7B-1%7D%7B3%7D)
Therefore ![a = \frac{-1}{3}.](https://tex.z-dn.net/?f=a%20%3D%20%5Cfrac%7B-1%7D%7B3%7D.)
Answer:
2
Step-by-step explanation:
Answer:
5/2 x 1/2
Step-by-step explanation:
when you multiply fractions you multiply trait across meaning you do 5*1 and 2*2 which leaves you with 5/4 and that is equivalent to 1 &1/4
