Solve the system of equations. x + 3y = −12x + 2y = 6

Mathematics
1 answer:
UkoKoshka [18]3 years ago
7 0

Answer:

x=-3/19

y=39/19

Step-by-step explanation:

the equations can be written as the following system

x+3y=6\\-12x+2y=6

If the second equation is multiplied by 3/2 it will become -18x+3y=9

If that equation is then subtracted with the first you will obtain the following

-19x=3, it means x=-3/19

The other variable is obtained by substituting the new value for x in the first equationx+3y=6, thus we obtain that y=39/19

What is the domain of the radical function shown on the graph? GRAPH IS IN THE PIC BELOW. A.
irina1246 [14]

Given:

The graph of a radical function.

To find:

The domain of the given radical function.

Solution:

We know that, domain is the set of input values or we can say domain is the set of x-values for which the function is defined.

From the given graph it is clear that, for each value of x there is a y-value. It means the function is defined for all real values of x. So,

Domain = Set of all real numbers.

Therefore, the correct option is A.
