crimeas [40]

X= 9th student test score

Add the 9 test scores and divide that total by 9 to equal the average.

(56 + 92 + 78 + 64 + 85 + 83 + 91 + 77 + x)/9= 78
add in parentheses

(626 + x)/9= 78
multiply both sides by 9

626 + x= 702
subtract 626 from both sides

x= 76

ANSWER: 76 is the score needed by the 9th student for a mean of 78.

Hope this helps! :)

<h2>Solution : </h2>

y = -2|x +1|

→ |x + 1| = -y/2

→ x+1 = y/2

→ x + 1 belongs to R

→ x belongs to R

Domain = R

Range = y = -2(R)

→( -∞ , 0)
