Answer:
Option 2: (1, 0) and (0, -5)
Step-by-step explanation:
Let's solve this system of equations using the elimination method.
Start by labelling the two equations.
5x -y= 5 -----(1)
5x² -y= 5 -----(2)
(2) -(1):
5x² -y -(5x -y)= 5 -5
Expand:
5x² -y -5x +y= 0
5x² -5x= 0
Factorise:
5x(x -1)= 0
5x= 0 or x -1= 0
x= 0 or x= 1
Now that we have found the x values, we can substitute them into either equations to solve for y.
Substitute into (1):
5(0) -y= 5 or 5(1) -y= 5
0 -y= 5 or -y= 5 -5
y= -5 or -y= 0
y= 0
Thus, the solutions are (0, -5) and (1, 0).
The given equation is

Here we have to solve for n. First we need to get rid of the denominators and for that we do cross multiplication .

Now we need to isolate n. And for that we need to get rid of 12, by dividing both sides by 12



And that's the required value of n .
Answer:
= 5u
Step-by-step explanation:
You combine like terms
( 2u+ 8u = 10u )
( -5u + 10 u =5u)
Answer:60
Step-by-step explanation:
3 ways to pick the meat,
4 ways to pick the eggs,
5 ways to pick the cereal.
For each of the 3 meats you can pick any of the 4 egg dishes, so 12 ways to pick a meat and an egg dish.
For each of those 12 you can pick any of the 5 cereals, so 60 ways to pick the meal.
If the y intercept isn't -5 go to ur coordinate that is given and find where the y intercept is and plug in the y intercept to y=mx+b
