Answer:

{x,y}={4,7}

Step-by-step explanation:

3x - y = 5

x+ 4y = 32

y + 3x = 5   ,      4y + x = 32  

x = -4y + 32

3•(-4y+32) - y = 5

- 13y = -91

13y = 91  

 y = 7

x = -4y+32

 y = 7

x = -4(7)+32 = 4

so the final solution is:

⇒x = -4(7)+32 = 4

Hello there.

6(8 - 2y) = 4y

To solve for this, we need to apply the Distributive Property to the left side of the equation. This property allows us to multiply the number outside of the parenthesis by all numbers inside of the parenthesis.

6(8 - 2y)
6(8) + 6(-2y)
48 - 12y

Now, let’s take a look at our equation.

-12y + 48 = 4y

To make things more simple, we’ll add 12y to both sides of the equation. This will cancel out -12y on the left side of the equation and will turn 4y on the right side of the equation into 16y.

Our new equation is:

16y = 48

Now all we need to do is divide both sides by 16 to solve for y.

16y / 16 = y
48 / 16 = 3

Our final answer and solution is:

Y = 3

I hope this helps!

ANSWER ASAP PLS 20 POINTS! Which graph represents the piecewise defined function? y= {3 if x&lt;-2 0 if x=1 -1 if x&gt;1
Otrada [13]

Answer:

It is the third option. (the one which has a black point at X=1, Y=1)

Step-by-step explanation:

For simplicity what you should do is, you should satisfy the second condition that is, y=0 if x=1.

Here only the third option is satisfying this condition.

Whenever there is is a white circle or a white point it means that the point does not satisfy the condition and the the function is not defined at that point. And the black point means that the circle is defined at that point and satisfies the condition.

Henceforth, the correct answer is the third option.
