Answer:

Option D - (4, 5)

Step-by-step explanation:

The y cancels out

3x + x = 27 - 11

4x = 16

Divide both sides by 4

x = 4

Then substitute to get to get y

4 - 3y = -11

Subtract 4 from both sides

-3y = -15

Divide both sides by -3

y = 5

x is 4

y is 5

(4, 5)

When you add them by elimination method you do like
3x+3y=27
X - 3y=-11
__________
+3y And -3y gets cancels out
You left with
3x=27
X=-11
_______
4x=16
Now you divide 4 on Both side so you get X=4
And now you plug your x value in any of the equation above and you get y value as Y=5

In the equation g+h= -5, if g=11 find value of h
Lesechka [4]

Answer:  " h = -16 " .

_________________

Step-by-step explanation:

_________________

Given the equation:

g + h = -5 ;  and given:  " g = 11 " ;

Plug in "11" for "g" ; and solve for "h" ;

_________________

11 + h = -5 ;

Subtract "11" from each side of the equation;

 to isolate "h" on one side of the equation;

  & to solve for "h" :

_________________

11 + h − 11 = -5 − 11 ;

to get:

  h = -16 .

Complete the table of values for the equation y=x2-2x-1
lord [1]
  • y = x^2 - 2x - 1

1. If x = -2, then

y = (-2)^2 - 2(-2) - 1

= 4 + 4 - 1

= 7

2. If x = 0, then

y = (0)^2 - 2(0) - 1

= 0 - 0 - 1

= -1

3. If x = 2, then

y = (2)^2 - 2(2) - 1

= 4 - 4 - 1

= -1

4. If x = 3, then

y = (3)^2 - 2(3) - 1

= 9 - 6 - 1

= 2

Hope you could understand.

If you have any query, feel free to ask.
