Answer:
<h2>
( 2 , - 3 )</h2>
Step-by-step explanation:
Using elimination method:
2x - y = 7
3x + y = 3
--------------
5x = 10
Divide both sides of the equation by 5
Calculate
Now, substitute the given value of X in the equation
3x + y = 3
Multiply the numbers
Move constant to R.H.S and change it's sign
Calculate
The possible solution of this system is the ordered pair ( x , y )
<h3>
( x , y ) = ( 2 , -3 )</h3>
---------------------------------------------------------------------
Check if the given ordered pair is the solution of the system of equation
Simplify the equalities
Since all of the equalities are true, the ordered pair is the solution of the system
<h3>
( x , y ) = ( 2 , - 3 )</h3>
Hope this helps..
Best regards!!
Answer:
if x gets +2 then y gets 3 taken away
Answer:
20%
Step-by-step explanation:
20%
220 divided by 275 to get .8
80% then 80% minus 100%
=20%
Hey there! I'm happy to help!
Imagine the line that is created when you connect the two points (the distance between the two points).
You can create a right triangle where this distance is the hypotenuse where the two legs are the change in x and y. So, if you take those changes in x and y, you can use the Pythagorean Theorem (a²+b²=c²) to find the distance between the two points, which is the hypotenuse.
Our change in x is 9 because 9-0 is 9.
We square it
9²=81
Our change in y is 5 as -1-(-6) or -1+6 is 5.
5²=25
We add these.
81+25=106
We square root and round to the nearest tenth.
√106≈10.3
So, our distance is 10.3.
This Pythagorean Theorem method actually gives us a formula called the distance formula that you can use to find the distance between points.
Have a wonderful day and keep on learning! :D
