Answer:
y= -2/5+5
Step-by-step explanation:
A line must always be written in the form y= and the line given is not. Dividing both sides of the equation by 2 you get y=5/2x-4. This is the equation of the line given.
Perpendicular line have gradients that, when they are multiplied, they are equal to -1
The line given multiplied by the gradient of the line(the one required to find)= - 1. That is 5/2×line= -1.
Dividing both sides of the equation by 5/2 you'll get - 2/5. This is the gradient of the line required.
Using the general formula y=mx+c substitute the gradient into the equation. You'll get something like this y= -2/5x+c.
Substitute the given point into the equation. You'll get something like this 3= -2/5(5)+c.
Calculate the value of c. You'll get c=5.
Substitute the value of c into the original equation. You'll get something like this y= -2/5+5
This is the equation: y= -2/5+5
Answer:
-2-20p <em>OR</em> -20p-2
Step-by-step explanation:
2-4(5p+1)
Rewrite (the spaces can help me to view the different parts):
2 -4(5p + 1)
Distribute:
2 -20p -4
Combine like terms:
-2-20p
Answer:
-2-20p <em>OR</em> -20p-2
Answer:
4 ways of choosing
Step-by-step explanation:
If you want to choose 3 objects, without replacement, from the 4 objects which are distinct, then permutation i.e then their arrangement doesn't really matter. Only their combination will be considered
That means, order of choosing doesn't matter,
pencil/ eraser/ desk will be same as eraser/ desk/ pencil.
Number of ways of selecting 3 objects out of 4 distinct objects is:
⁴C₃ = 
⁴C₃ = 
⁴C₃ = 4
So, there are 4 ways of choosing
