Answer:
y=9.5x-.5 Y2 minus Y1 divided by X2 minus X1 gets you the slope
Answer:
x = -1
Step-by-step explanation:
3^x = 1/3
3^x= 3^-1
x=-1
Most quadratic functions(which is what you have there, to a degree of 2) are solved using factoring and the zero product law. If you can not factor then you have to use the quadratic formula or graph it. However this one can be factored.
It's pretty simple to just factor it by inspection but I use the chart method, if you know decomposition that works as well.
Factoring gives us,

Then you set each factor to 0 and solve for x,



And the second one,


The solutions to this equation are
x = -1/2, 3
There is a similar shortcut for multiplying decimal numbers by numbers such as 10, 100, and 1000: Move the decimal point to the right as many places as there are zeros in the factor. Move the decimal point one step to the right (10 has one zero). Move the decimal point two steps to the right (100 has two zeros).
Answer:

Step-by-step explanation:
One of the rules of logarithms is ...
log(a^b) = b·log(a)
So ...
