Answer:
15
Step-by-step explanation:
(18+22+17+x)/4=18
18+22+17+x=18×4
57+x=72
x=72-57
x=15
Y= -5/3x + 2
To find slope:
-8-7 / 6 - (-3) = -5/3
Plug in x and y from one of the points to the equation to find b
7 = -5/3 (-3) + b
B = 2
Put it all together:
y = -5/3x + 2
Answer:
The correct option is c.
Step-by-step explanation:
The given equation is

The given inequality is

A point will contained in solution set if the above inequality satisfied by that point.
Check the point (0,-3),


This statement is false, therefore option a is incorrect.
Check the point (-3,0),


This statement is false, therefore option b is incorrect.
Check the point (3,3),


This statement is true, therefore option c is correct.
Check the point (-3,-3),


This statement is false, therefore option d is incorrect.
The answer is 15.525. All you have to do is divide 279.45 by 18 which gives you 15.525.
