Answer:
Interchange the variables and solve for y
inverse = y = ±√x+12
Step-by-step explanation:
y=x^2-12 becomes x=y^2-12
x+12=y^2
±√x+12=y
8 feet minus 7 feet, 10 3/4 inches is equal to 1 foot minus 10 3/4 inches, or 12-(10 3/4) inches. This is 1 1/4 inches.
It opens downwards so it looks like this “n”. That is because a in the formula is a negative number in this situation
Answer:
r = -6
Step-by-step explanation:
6r + 7 = 13 + 7r
-6r both sides
7 = 13 + r
-7 both sides
r + 6 = 0
-6 both sides
r = -6
Answer:
system 4.
Step-by-step explanation:
3x+6y=9
multiply by 2
6x+12y=18 ....(1)
-2x+-4y=4
multiply by 3
-6x-12y=12 ...(2)
add (1) and (2)
0+0=30
which is impossible .It has no solutions.
