Answer:
It's division because to get x by itself, you need to divide both sides. X = 9
Step-by-step explanation:
6x = 54
Divide both sides by 6
54/6 = 9
Answer:
Step-by-step explanation:
because both equations do not have matching numbers for the x or y variable, and both equations are positive you are going to have to multiply each equation by a number so that there will be at least one variable with the same number but with opposite signs.
it does not matter which variable you choose.
lets use y because 2 and 3 are smaller then 2 and 5.
so lets multiply the first equation by 2 in order to get y equal to 6.
2(2x)+2(3y)=(2)6
(do not forget to multiply what the equation is equal to also)
4x+6y=12
now for the second equation we need y to equal negative 6
-3(5x)+-3(2y)=-3(4)
-15x-6y=-12
now lets put the 2 new equations next to each other and see what we can cancel out
4x+6y=12
-15x-6y=-12
-11x=0
x=0
now plug 0 in for x and solve for y (it does not matter which of the 4 equations you choose to solve.
2(0)+3y=6
3y=6
y=2
so your answer is x=0, y=2
Step-by-step explanation:
When deciding where to put an ordered pair on a graph its important to understand how ordered pairs work.
An ordered pair is split up into to pieces
(x,y) or number example (3,5)
When graphing the x coordinate will fall on your horizontal line or the line that looks like the horizon.
When graphing the y coordinate it will fall on your vertical line or the line that goes right up into the sky like a rocket.
To graph (3,5)
Go to the right 3 and up 5
Sometimes helps to use both fingers to keep your spot. Slide both fingers until they collide and that's where you would plot your point!
Hope this helps if you have an questions just comment and ill try to explain further.
Answer:
Hey there!
A congruence transformation maintains the size of the shape.
Thus, a dilation with scale factor 2 is not a congruence transformation.
Let me know if this helps :)
When simplified the answer is -2n^3+13
