Answer:
The Answer is 25
Step-by-step explanation:
Answer:
Step-by-step explanation:
Given
Required
Find a
Take log of both sides
Apply law of logarithm
Divide both sides by a
Multiply both sides by -9
Apply law of logarithm
Cancel out log
Rewrite as:
Apply law of indices
Y=-x+2
2y=x-8
these two lines both go through the point (4,-2)
solve: substitute the y in the second equation with (-x+2):
2(-x+2)=x-8
-2x+4=x-8
add 2x on both sides:
4=3x-8
add 8 on both sides: 12=3x
divide by 3 on both sides: x=4.
find y: y=-x+2=-4+2=-2
the solution is (4,-2)
