Answer:

x = 39.1

Step-by-step explanation:

<u>Points to remember</u>

Mean of a data set is given by

Mean = (sum of data set)/Total number of data

<u>To find the value of x</u>

It is given a data set

31.7, 42.8, 26.4, x

Mean = 35

Sum of data set = 31.7 + 42.8 + 26.4 + x = 100.9 + x

(100.9 + x)/4 = 35

100.9 + x = 35 * 4 = 140

x = 140 - 100.9 = 39.1

Therefore x = 39.1

We're given a parabola

y=x^2-4

and a line

y = 2x+b

The zeros of the parabola are

0=x^2-4

4=x^2

x=\pm 2

We see that (-2,0) is on the line as well:

y = 2x+b

0 = 2(-2)+b

b=4
