Answer:
Step-by-step explanation:
So we have the equation:
First, separate the second term:
Let u equal 5ˣ. So:
Combine like terms:
Divide both sides by 6:
Substitute back u:
Take the base 5 logarithm of both sides:
The left cancels:
Evaluate the right:
So, our answer is 2.
And we're done!
Answer:
Area = 12 square centimetres
Answer is A, y us smaller/equal to 2 and y is smaller/equal to X
Substitution
y = 2x - 12
y = -x + 3
-x + 3 = 2x - 12
+ x + x
-----------------------------
3 = 3x - 12
+ 12 + 12
-----------------------
15 = 3x
------ ------
3 3
x = 5
y = 2(5) - 12
y = 10 - 12
y = -2
The final answer is (5,-2).
