Answer:
n=3
Step-by-step explanation:
-5 (6n +8) =50
First distribute the -5 to 6n and 8. Remember to multiply with the sign!
so -5 x 6n and -5 x 8
which = -30n and -40
so our new equation is
-30n - 40=50
we add 40 to the other side since we want the answer of the variable
-30n - 40 +40 = 50+40
-30n =90
we divide -30 from n to get n alone.
-30n/-30 = 90/-30
n=-3
We can check our answer by plugging it into the equation.
50= -5 (6(-3) +8)
50 = -5 (-18+8) -> 50= -5 (-10)=50
Answer:
x= -17
Step-by-step explanation:
When we have 2 points, we can find the slope using
m = (y2-y1)/(x2-x1)
Substituting what we know
1/5 = (0-3)/(x--2)
1/5 = -3/(x+2)
Using cross products
1*(x+2) = 5*(-3)
x+2 = -15
Subtract 2 from each side
x+2-2 = -15-2
x=-17
Answer:
y=2x/5-4x

A function will not have ANY repeating x values....it can have repeating y values...just not the x ones
so ur function is : (2,3) ,(1,3), (3,3) ....u see how u have no repeating x values
