Answer:
x = 95
Therefore the solution is 95
Step-by-step explanation:
<u><em>What is the solution to log Subscript 5 Baseline (x + 30) = 3</em></u>
<u><em /></u>
log₅(x+30) = 3
From our law of logarithm
5³ = x + 30
(but 5³ = 5 ×5×5=125)
125 = x + 30
Subtract 30 from both-side of the equation to get the value of x
125 - 30 = x + 30 -30
95 = x
x = 95
Therefore the solution is 95
We can check the correctness of our answer
log₅(x+30)
=log₅(95+30)
=log₅125
=log₅5³ ( Note: log₅5=1)
=1×3
=3
Answer:
y = 2x + 4
Step-by-step explanation:
You already know the slope, so now you need to find the y-intercept. You need to plug in the values of x and y into the equation, y = 2x + b.
y = 2x + b
2 = 2(-1) + b
2 = -2 + b
4 = b
First factor the second fraction's denominator.
It is a difference of squares so it can be factored as (y + 4)(y - 4)
Notice the first fraction's denominator is y + 4. So you already have that.
Therefore the LCD is (y + 4)(y - 4) :)
