Answer:
y = - 19
Step-by-step explanation:
Express 210 and 55 as products of their prime factors, that is
210 = 2 × 3 × 5 × 7
55 = 5 × 11
Identify the prime factors that both numbers have in common and multiply them.
Here only 5 is common, thus
HCF = 5
Thus
5 = 210 × 5 + 55y, that is
5 = 1050 + 55y ( subtract 1050 from both sides )
- 1045 = 55y ( divide both sides by 55 )
y = - 19
Answer:
It is a function
Step-by-step explanation:
A function is of the form:
![\left[\begin{array}{c}y_1&y_2&y_3\\-&-&-\\y_n\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7Dy_1%26y_2%26y_3%5C%5C-%26-%26-%5C%5Cy_n%5Cend%7Barray%7D%5Cright%5D)
Where each of the x values must be distinct.
The x values are referred to as domain while the y values are called range.
Having said that, the given data can be represented as follows:
----------- ![\left[\begin{array}{c}7&-8&-6\\-8&2\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7D7%26-8%26-6%5C%5C-8%262%5Cend%7Barray%7D%5Cright%5D)
<em>From the representation above, none of the x values are repeated.</em>
<em>Hence, it is a function</em>
Theoretically 10 because the 50/50 chance realistically though you'll get more or less
See picture. Hope it helps
