The best option is c

Step-by-step explanation:

The same textbooks contains a total of 848 pages . Which represent the total number of pages , y , of any number of the same textbooks , x.

The number of same text book = x

Each of this textbook contains a total of 848 pages .

The total number of pages can be computed as

y = 848x

for 4 same text book

y = 848 × 4 = 3392 pages

for 3 same text book

y = 848 × 3= 2544 pages

for 7 same text book

y = 848 × 7 = 5936 pages

for 8 same text book

y = 848 × 8 = 6784 pages

y = 848 × 11 = 9328 pages

How to tell if an ordered pair is a solution to a function
Evgen [1.6K]
A) yes
B) yes
C) no

For each of these, substitute the value of x in the ordered pair into x in the function.

For A, x = -5; -5<2, so the piece of the function we want is f(x) = 3.  In our ordered pair, y=f(x)=3, so yes, it is a solution.

For B, x = 2; 2≤2<6, so the piece of the function we want is f(x) = -x+1.  In our ordered pair, y=f(x)=-1; -2+1=-1, so yes, it is a solution.

For C, x = 8; 8≥6, so the piece of the function we want is f(x) = x.  In our ordered pair, y=f(x)=-7; -7≠8, so no, it is not a solution.
