Answer:
Step-by-step explanation:
So you know the coords for the angle which is (1, 4).
Another coord might be (2, 5) or (0,3)
So we can find the slope
rise/run=1/1
so m=1
Sub in coords like (1,4) to find y-int
y=mx+b
4=1(1)+b
b=3
Thus y=x+3
Answer:
x = -7
Step-by-step explanation:
This is an exponential equation.

We need to take log(or ln) of both sides and use logarithm property to solve this.
So, let's take ln of both sides, so we have:

Now, we will use this property shown below to further simplify:

So, we now have:

The value of x is -7
