Can someone please explain to me how to do numbers 2 and 3??

The answer to question 3 is 1 person orders chicken and the other 5 had steak dinner.

the way you work this out is you half 6 which is three and then do 3x14 and 3x17
3x14=42
3x17=51
42+51=93
this is too less so you have to do less of the cheaper meal (14) and more of the dearer one (17) so I went to 1x14 and 5x17
1x14=14
5x17=85
14+85=99
add these together and it makes 99

the answer to question 14 is 5 adults and 3 students

to do this you do exactly the same as how you do question 3

which equation is the quadratic variation equation for the relatonship? the variable y varies directly with x^2 and y=36 when x=

svetoff [14.1K]

For this case we have a direct variation of the form:

$y = kx ^ 2$

Where,

<em>k: proportionality constant </em>

We must find the value of k.

For this, we use the following data:

$y = 36\\x = 3$

Therefore, replacing values we have:

$36 = k (3) ^ 2$

Rewriting:

$36 = 9k$

Clearing the value of k we have:

$k = \frac {36} {9}\\k = 4$

Therefore, the direct variation equation is given by:

$y = 4x ^ 2$

Answer:

The quadratic variation equation for the relatonship is:

$y = 4x ^ 2$
