Answer:
− y ln (27) + ln (9x) = 0
Answer:
A. Exactly one solution
Step-by-step explanation:
Solve the system of equations.
y = x + 1
y = 2x - 5
Substitute one equation into the other.
y = 2x - 5
x + 1 = 2x - 5
Subtract 2x from both sides.
-x + 1 = -5
Subtract 1 from both sides.
-x = -6
Multiply both sides by -1.
x = 6
Put it back into the other equation.
y = x + 1
y = 6 + 1
Add.
y = 7
The solution is (6, 7). Since the equations aren't equal, there are not infinitely many solutions, but since there is a solution found, we can determine that there is exactly one solution.
There are 3 numbers, first let list all the factors of 12, 1,2,3,4,6,12 and now which are multiple of 3, 3, 6,12 therefore we are left with 1,2,4!
What measurements are they asking it in
Cross multiply
20(x+1)=14(x-1)
20x+20=14x-14
Subtract 14x on each side giving you
6x+20=-14
Subtract 20 on each side giving you
6x=-34
x=-34/6. Simplifying that you get x=-17/3. I hope this helps!!!
