Answer: (4,2). Explanation: In the elimination method you either add or subtract the equations to get an equation in one variable. When the coefficients of one variable are opposites you add the equations to eliminate a variable and when the coefficients of one variable are equal you subtract the equations to eliminate a variable. The Elimination Method
Step 1: Multiply each equation by a suitable number so that the two equations have the same leading coefficient. ...
Step 2: Subtract the second equation from the first.
Step 3: Solve this new equation for y.
Step 4: Substitute y = 2 into either Equation 1 or Equation 2 above and solve for x.
variable equation. It is relatively difficult to determine the values of x and y without manipulating the equations. If one adds the two equations together, the x s cancel out; the x is eliminated from the problem. Hence it is called the "elimination method”.

Find the length of the hypotenuse
Darina [25.2K]

Answer:

The Hypotenuse is side just opposite to the right angle.

Step-by-step explanation:

By Pythagoras' theorem,

c^2=a^2+b^2

c^2(hypotenuse to be found)= 30^2+ 16^2

<em>c^2=1156 </em>

<em><u>Therefore, c ( i.e. the hypotenuse) will be the square root of 1156. </u></em>

<em><u>The square root of 1156 is 34. </u></em>

<h2><em><u>Thus, c ( hypotenuse) = 34</u></em></h2>

Hope it helped :)

What is the distance between (2, -1) and (-1, -5) on the coordinate plane? 7 units 6 units 5 units 4 units
morpeh [17]
You can use the distance formula: 
<span>\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}
<span>
Plug in the given coordinates: 
</span><span>\sqrt{(-5-2)^2 + (-1+1)^2}

\sqrt{(7)^2 + (0)^2}

\sqrt{49+0}


\sqrt{49}=7

Final answer : 7units

Oxana [17]

Answer:

1. slope= 3/4x Y-intercept= 7

2. slope= 5x Y-intercept=8

3. slope= -2x Y-intercept=0

4. slope= 0 Y-intercept=12

*the table ones are difficult to type out but sorry if it doesnt make sense*

5. X Y=3x+4. Y

0 y=3(0)+4 4

1 y=3(1)+4 7

2 y=3(2)+4 10

3 y=3(3)+4 13

4 y=3(4)+4 16

6. X y=1/2x-1. Y

-2 y=1/2(-2)-1 -2

1 y=1/2(1)-1 1.5

4 y=1/2(4)-1 2

6 y=1/2(6)-1 3

9 y=1/2(9)-1 3.5

7. X. Y=5-2x Y

0 y=5-2(0) 5

1 y=5-2(1) 3

2 y=5-2(2) 1

3 y=5-2(3) -1

4 y=5-2(4) -3

I believe you need the graph for the last 3
