2x + 4y =8<br> X = 3y -6

Sergio [31]

{x,y} = {-2,3}

[1] 2x + 4y = 8

[2] x - 3y = -11

4y + 2x = 8

-3y + x = -11

Solve equation for the variable x

[2] x = 3y - 11

Plug this in for variable x in equation [1]

[1] 2•(3y-11) + 4y = 8

[1] 10y = 30

Solve equation [1] for the variable y

[1] 10y = 30

[1] y = 3

By now we know this much :

x = 3y-11

y = 3

Use the y value to solve for x

x = 3(3)-11 = -2

Solution :

{x,y} = {-2,3}

A) -180m
b) 510-180=+330m
+330/45=7.333m/s
c) total distance = 840m
average speed = 840/105
= 8m/s

Select either relation (if the set is a relation but not a function), function (if the set is both a relation and a function), o

galina1969 [7]

Answer: The correct options are

(A) relation

(B) function.

Step-by-step explanation: We are given to check whether the following set is a relation or a relation and a function or neither :

A = {(1, 2) (2, 2) (3, 2) (4, 2)} .

Let us consider the following two sets :

U = {1, 2, 3, 4} and V = {2}.

Then, we see that the Cartesian Product of U and V is given by

U × V = {(1, 2) (2, 2) (3, 2) (4, 2)}.

Since a relation is a subset of Cartesian product, so the given set A is a relation.

Also, we know that a relation is a function if every first element is associated with one second element.

Since the relation A satisfies this condition, so the relation A is a function.

Thus, the given set A is both a relation and a function.

Option (A) and (B) are correct.

There are 11 more goats than sheep in the farm. Together there are 137 animals in the farm. How many goats and how many sheep ar

VashaNatasha [74]

Answer:

The number of goats in the farm is $74$

The number of sheep in the farm is $63$

Step-by-step explanation:

Let

x----> the number of goats in the farm

y----> the number of sheep

we know that

$x+y=137$ ----> equation A

$x=y+11$ -----> equation B

substitute the equation B in equation A and solve for y

$(y+11)+y=137$

$2y=137-11$

$2y=126$

$y=126/2=63$

Find the value of x

$x=63+11=74$

therefore

The number of goats in the farm is $74$

The number of sheep in the farm is $63$
