Answer:
x = 1/5 , and x = - 1/5
Step-by-step explanation:
25x² – 1 = 0
5²x² - 1² = 0
(5x - 1)(5x + 1) = 0
5x -1 = 0, 5x + 1 = 0
x = 1/5 , x = - 1/5
Answer:
2/5
Step-by-step explanation:
Slope can be found with rise over run. So looking at the graph, the line rises 2 units and runs 5 units to the right. Therefore, the slope should be 2/5.

Step-by-step explanation:
<h3>To get the solution, we are looking for, we need to point out what we know.</h3>
1. We assume, that the number 50 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 50 is 100%, so we can write it down as 50=100%.
4. We know, that x is 98% of the output value, so we can write it down as x=98%.
5. Now we have two simple equations:
1) 50=100%
2) x=98%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
50/x=100%/98%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 98% of 50
50/x=100/98
(50/x)*x=(100/98)*x - we multiply both sides of the equation by x
50=1.02040816327*x - we divide both sides of the equation by (1.02040816327) to get x
50/1.02040816327=x
49=x
x=49
now we have:
<h3>98% of 50 = 49</h3>
