Answer:
5y + 15x = 25, 9x - y = -4
Step-by-step explanation:
The standard form is Ax + By = C. We can make this simple by first creating the slope intercept equations of both questions:
1. y = (-3/5)x + 5
2. y = 9x + 4
For the first one, we must first get rid of the denominator by multiplying everything by 5, so we get 5y = -15x + 25, and then you can add 3x to both sides to arrive at your first standard eqn, 5y + 15x = 25.
For the second, all you need to do is swap the y and the 4, subtracting both y and 4 from each side, arriving at 9x - y = -4
Answer:
Remember that logarithms are inverse of exponentials. That means the result of the logarithm is equal to the exponent of a power with the same base.
<h3>1. (a)</h3>
Notice that the result is one beacuse 
<h3>(b)</h3>
Because 
<h3>(c)</h3>
So, 
<h3>2. </h3>
I would say to thim that 
and 
are variables of the logarithm, which be solved by imagine the logarithm as an exponential like
In other words, the is the exponent and the is the result of the exponential.
