Answer:
y-7 = -2 (x-4)
Step-by-step explanation:
Point Slope Form:
, where m is the slope of the line
They tell you that the line has a slope of -2, so that will go in the first yellow box. They also tell you that the line passes through the point (4, 7), so those are the values for x1 and y1. They've already filled in y1 with 7, so x1 (which is 4) will go in the second yellow box
y-7 = -2 (x-4)
Attached is both solutions in detail.

Well, I do not know if you mean 93x = 7 or 9^3x = 7.
So, I will provide the solution for both cases.
In case of 93x = 7:
This case is simple, all you have to do is isolate the x. You need to get rid of the coefficient which is 93. You can simply do this by dividing both sides of the equation by 93 as follows:
93x = 7
93x / 93 = 7/93
x = 7/93
In case of 9^3x = 7:
Now, we need to get rid of the power. The only function that can do this is the log function.
So, we will start by taking log base 10 for both sides of the equation as follows:
9^3x = 7
log(9^3x) = log(7)
This will give:
3x * log(9) = log(7)
Now, the final step is to isolate the x as we did before. To do this, we will need to get rid of 3log(9). This can be done by dividing both sides of the equation by 3log(9) as follows:
3x * log(9) / 3log(9) = log(7) / 3log(9)
This will give us:
x = log(7) / 3log(9) = 0.2952
Hope this helps :)
Hello!
Odd functions are functions that are symmetric with respect to the origin.
Even functions are functions that are symmetric with with respect to the y-axis.
Therefore, the graph of y = sin(x) + cos(x) has
no symmetry (neither).
