Since no base is stated, assume base 10
remember
loga-logb=log(a/b)
also
translates to
and log(a^z)=zlog(a)
log25x-log5=2 means
translates to
simplies to
translates to
expands to
100=5x
divide both sides by 5
20=x

Answer:</h2>
<h2>
Step-by-step explanation:</h2>
From the given graph, we can know two points:
Using the slope intercept form of the equation of a line, we get:
Where the slope is and the y-intercept is
From mathematics, we know that a system of two linear equations has no solution if and only if the two equations have the same slope, but not the same y-intercept. So, from the options, the second equation is:
And the slope intercept form of this equation is:
So the slope is and the y-intercept is , the systems formed by these two equations has no solution.
Answer:
one solution
Step-by-step explanation:
since the variables are only to a power of one, the options are no solutions, one solution, and infinitely many solutions.
using the distributive property, 10(x+4)= 10x + 40. simplify the equation 10x + 40 - 3 = 14x +1 to 10x + 37 = 14x + 1. move variables to one side and constants to another to get 4x = 36. divide to get x=6. so the answer is one solution
since we don't have something like 1=0 where two unequal constants are said to be equal, the answer isn't no solutions
since we dont have something like 1=1 where the two sides of the equation are equal no matter what x is, the answer isn't infinitely many solutions
