The given equation is: 
To find the line perpendicular to it, we interchange coefficients and switch the signs of one coefficient.
The equation to a line perpendicular to it is:
$ 2y-x=c$
where, $c$ is some constant we have determine using the condition given.
It passes through $(2,-1)$
Put the point in our equation:
$2(-1)-(2)=c$
$c=-2-2$
$c=-4$
The final equation is:
$\boxed{ 2y-x=-4}$
Answer:
2500
Step-by-step explanation:
The driveway is 25 meters.
In every meter there is 100 centimeters.
So 25 times 100 is 2500 centimeters.
Answer: 31 mint plants
Step-by-step explanation:
We will have mint plants over total plants:
29/29+29 = 29/58 = 1/2
Now, we will multiply 62 by 1/2 to guess how many mint plants will be stocked.
62* 1/2 = 31
We should expect about 31 plants of the total plants to be mint plants.
Answer:
15y / 8
Step-by-step explanation:
Multiplying by 2 to get the common denominator.
3y / 4 * 2 = 6y / 8
Combine like terms.
6y / 8 + 9y / 8
Final Answer:
15y / 8
Answer:
315 degrees
Step-by-step explanation:
Assume that the dial is a perfect circle and therefore makes a full 360 degree rotation. If the dial is already turned 45 degrees, the rotation angle required to return all the way to the initial position is:
You will need to rotate 315 degrees.
