How do you solve this problem.
there were 24 dinner tables with 8 chairs at each table. if 3/4 of the dinner tables are full how mant seats were used

144

Step-by-step explanation:

3/4 of the dinner tables are full (each table is 3/4 full)

3/4 of 8 =6

6*24 =144

 OR

3/4 of the dinner tables are full  (3/4 of all tables)

3/4 of 24 =18

18*8=144

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
