Answer:

x = 0 and y = -2

Step-by-step explanation:

x - 2y = 4 and X - 1y = 2

you mentioned elemination aka substraction

so you when substract x - x =  0  -2y -( -y) = -y and 4 -2 = 2

so - y = 2

or y = 2

now substitute the numbers

x + 4 = 4

x = 0

and try it with one of the equation  or sometimes trying on both of them can be very helpful

Answer:

A: an = 6n - 9

Step-by-step explanation:

third term in an arithmetic sequence is 9

a3 = a + 2d

a + 2d = 9

the fifth term is 21

a5 = a + 4d

a + 4d = 21

a + 2d = 9 (1)

a + 4d = 21 (2)

Subtract (1) from (2) to eliminate a

4d - 2d = 21 - 9

2d = 12

d = 12/2

d = 6

Substitute d = 6 into (1)

a + 2d = 9 (1)

a + 2(6) = 9

a + 12 = 9

a = 9 - 12

a = -3

nth term of this sequence = a + (n - 1)d

= -3 + (n - 1)6

= -3 + 6n - 6

= 6n - 9

an = 6n - 9

Answer:

1. 2x + 3y = 240 AND x + y = 100

Nayeli sold 60 cups of lemonade and 40 cups of orange juice.

Step-by-step explanation:

Let

Number of cups of lemonade sold = x

Number of cups of orange juice sold = y

The system of equation could be represented by:

2x + 3y = 240 (1)

x + y = 100 (2)

from (2)

x = 100 - y

Substitute into (1)

2x + 3y = 240 (1)

2(100 - y) + 3y = 240

200 - 2y + 3y = 240

- 2y + 3y = 240 - 200

y = 40 cups

Substitute y = 40 into (2)

x + y = 100 (2)

x + 40 = 100

x = 100 - 40

x = 60 cups

Nayeli sold 60 cups of lemonade and 40 cups of orange juice.

(x, y) = (60, 40)

Answer: 150 degrees

Step-by-step explanation:

The number of degrees did it rotate altogether should be considered as the 150 degrees.

Since A sprinkler rotates 75°, pauses, and then rotates another 75

So, here total degrees be like

= 75 degrees + 75 degrees

= 150 degrees

hence, The number of degrees did it rotate altogether should be considered as the 150 degrees.

Answer:

$20.24

Step-by-step explanation:

Since the 25% discount takes off a quarter of the price, we multiply 24.99 by 3/4

24.99 x 3/4 = 18.74

So with the discount and without tax, the cost of the jacket is 18.74

Then we add 8% for sales tax

8% of 18.74 is $1.50

18.74 + 1.5 = 20.24

So the final cost of the jacket is $20.24

Answer:

w = 15

Step-by-step explanation:

We have an expression and are asked to solve for w.

-19w + 11 = -17w - 19

Subtract 11 from both sides :

-19w = -17w - 30

Add 17w to both sides :

-2w = -30

Divide -2 from both sides to isolate w :

w = 15

Answer:

Step-by-step explanation:

The coefficient of a variable is always the number before the variable, if there is no number before a variable the coefficient is always 1.

In this case, since the subtraction sign is before the variable, you will need to make the variable positive by making the coefficient of variable y, -1.

In short terms, your answer is -1. :)

Answer:

A

Step-by-step explanation:

The solution that is not the same as the solutions to the system of equations is 2x - 2y = 5.

Solutions are the values of an equation where the values are substituted in the variables of the equation and make the equality in the equation true.

We have,

2x + 3y = 1 _____(1)

x - y = 5 _______(2)

From (1) and (2) we get,

x = 5 + y

2 (5 + y) + 3y = 1

10 + 2y + 3y = 1

10 + 5y = 1

5y = -9

y = -9/5

Now,

x = 5 - 9/5

x = (25 - 9)/5

x = 16/5

The solutions are x = 16/5 and y = -9/5.

Now,

(1) 3x + 2y=6

3 x (16/5) + 2 x (-9/5) = 6

48/5 - 18/5 = 6

30/5 = 6

6 = 6

(2) 5y = -9

5 x (-9/5) = -9

-9 = -9

(3) 2x - 2y = 5

2 x (16/5) - 2 x (-9/5) = 5

32/5 + 18/5 = 5

50/5 = 5

10 ≠ 5

(4) 4x + 6y = 2

4 x (16/5) + 6 x (-9/5) = 2

64/5 - 54/5 = 2

10/5 = 2

2 = 2

Thus,

3x+2y=6, 5y=-9, and 4x+6y=2 have the same solutions.
