If the H.C.F of 210 and 55 is expressible in the form of 210*5 + 55y , find 'y' ?
Ilya [14]

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

Decide whether the relation is a function:<br> {(-3, 7), (1, -8), (6, -6), (7-8), (12, 2)}
lakkis [162]

Answer:

It is a function

Step-by-step explanation:

A function is of the form:

\left[\begin{array}{c}x_1&x_2&x_3\\-&-&-\\x_n\end{array}\right]            \left[\begin{array}{c}y_1&y_2&y_3\\-&-&-\\y_n\end{array}\right]

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}-3&1&6\\7&12\end{array}\right] ----------- \left[\begin{array}{c}7&-8&-6\\-8&2\end{array}\right]

<em>From the representation above, none of the x values are repeated.</em>

<em>Hence, it is a function</em>
