Answer:
Electricity bill is 175
<em />
Step-by-step explanation:
Given
monthly
Required
Determine the electricity bill
If each roommate pays 425, then 5 roommates pay 5 * 425
This implies that: the monthly cost of room, gas and electricity add up to 2125.
In other words,
<em>Hence, the electricity bill is 175</em>
X-3y=-15
-3y=-x-15
-1(-3y=-x-15)
3y=x+15
3/3y=1/3x+15/3
y=1/3x+5
It is good equation. Look, that:
81 = 3 x 3 x 3 x 3 = 3^4.
So you have to solve:
3^x = 3^4
exponents have to be the same, so
x=4
That's mean that A(4) = 81
