Line s has a slope of 7/4. Line t is perpendicular to s. What is the slope of line t?

Step-by-step explanation:

The formula governing this situation is

m1 * m2 = - 1

Method One

So let m1 = 7/4

(7/4)*m2 = - 1                      Multiply by 4

7*m2 = -1*4                         Divide by 7

m2 = -4/7

Method Two

Most people teaching this try to get you to use reciprocals. If you know how to do that then the answer is much simpler.

7/4 m2 = -1                        Multiply by 4/7

4/7 * 7/4*m2 = - 1 * 4/7      

m2 = -4/7

However if you are not comfortable with reciprocals, then then the thing to do is to handle them the way I showed you in the first method.

the answer is 4.8 units on e2020.

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
