Given y = 2x2 - 10x. find all real values of x for which y = -3.

 The required values of x are

Step-by-step explanation:  We are given the following function of x :

We are to find all real values of x such that y = -3.

To find the required values of x, we must substitute y = -3 in equation (i).

Therefore, from equation (i), we have

We notice that both the values of x are real numbers.

Thus, the required values of x are

a) 32pie square meters

step-by-step explanation:

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 : )
