The sum of two numbers is 15. Using x to represent the smaller of the two numbers, translate "the sum of twice the smaller numbe
Paladinen [302]

Answer:

Step-by-step explanation: Let x be the smaller and y be the largest number.

Since x+y=13, we deduce y=13-x

Now, for the translation: "two more than the larger number" is y+2 , while "twice the smaller" is 2x

Their sum is y+2+2x

And since we know that y=13-x, we have y+2+2x=13-x+2+2=15+x

Pleaseee help me with this only 3 questions!!!!
ElenaW [278]

Answer:

2. quadrant 4

3. quadrant 2

4. quadrant 3

Step-by-step explanation:

You can refer to the picture.

2. Since tan\theta less than 0 which means  tan\theta is negative, sin\theta less than 0 which means  sin\theta is negative.

So, the angle lies in quadrant 4 (Cos quadrant)

3. Since tan\theta less than 0 which means  tan\theta is negative, cos\theta less than 0 which means  cos\theta is negative.

So, the angle lies in quadrant 2 (Sin quadrant)

4. Since tan\theta more than 0 which means  tan\theta is positive, sin\theta less than 0 which means  sin\theta is negative.

So, the angle lies in quadrant 3 (tan quadrant)

Solve the system of equations 4x+5y=-1 and -5x-8y=10 by combining the equations.
Flura [38]

The solutions to the given system of equations are x = 6 and y = -5

<h3>Simultaneous linear equations</h3>

From the question, we are to solve the given system of equations

The given system of equation is

4x+5y=-1

-5x-8y=10

Multiply the <u>first equation</u> by 5 and the <u>second equation</u> by 4

5× (4x+5y=-1)

4× (-5x-8y=10)

20x + 25y = -5

-20x - 32y = 40

------------------------

0x + (-7y) = 35

-7y = 35

y = 35/-7

y = -5

Substitute the value of y into the first equation to find x

4x + 5y = -1

4x + 5(-5) = -1

4x -25 = -1

4x = -1 +25

4x = 24

x = 24/4

x = 6

Hence, the solutions to the given system of equations are x = 6 and y = -5
