Answer:
Solution given:
we know that
product of power and power is added and power to power is multiplied for same base only.
I.E.
product of same base but different power:
power to power :
By using above property
![2^{[6+6]}=2^{12}](https://tex.z-dn.net/?f=2%5E%7B%5B6%2B6%5D%7D%3D2%5E%7B12%7D)
Answer:
The answer is A
Step-by-step explanation:
I remember looking this up because my gamertag on xbox is Auroras Lights
What happens is our ozone layer is thinning out each year and solar wind particles come in our atmosphere where they mix with the ions. This creates a colorful light show in the sky that we see. It happens at the poles because of a magnetic pull.
Answer:
(0,7)
Step-by-step explanation:
(I'm assuming you have to solve the system of equations)
3x -10y = -70
4x +9y = 63
Solving by elimination.
Eliminate x first, so we need the x-component of both equations to have the same number but opposite sign. So i'm going to multiply the first by -4 and the second by +3.
//I could have also done +3 to first and -4 to second
-4(3x -10y = -70)
3(4x +9y = 63)
-12x +40y = 280
12x +27y = 189
Add the equations //x's cancel
67y = 469
Divide both side by 67, y=7
Plug in y into any original equation to solve to x
3x - 10(7) = -70
3x -70 = -70
3x = 0
x=0
Answer:
x = -12.5
Step-by-step explanation:
your goal is to get x alone so
-2x - 10 = 15
(add ten to both sides)
-2x = 25
(divide -2 to both sides)
x = -12.5
remember that whatever u do to one side of the equation, you have to do to the other so they even out!
