Answer: umm wheres y at? after the Equal sign?
Step-by-step explanation:
Solve each equation separately:
(-1, 3) Has to be a point that fits both equations
y = 2x + ____
Plug in Values:
3 = 2(-1) + ____
3 = -2 + ____
___ = 5
First Blank: 5
y = ___x - 1
Plug in Values:
3 = ___(-1) - 1
4 = ___(-1)
___ = -4
Second Blank: -4
The answer is B) it shifts up and to the right
The equation (1) is divided by 2 to create new equivalent system of equations.
Step-by-step explanation:
The given systems of equations are:
![-4x+8y=16\,\,\,(1)\\2x+4y=32\,\,\,(2)](https://tex.z-dn.net/?f=-4x%2B8y%3D16%5C%2C%5C%2C%5C%2C%281%29%5C%5C2x%2B4y%3D32%5C%2C%5C%2C%5C%2C%282%29)
Considering 8y instead of 8 in eq(1)
We need to identify what action was completed to create this new equivalent system of equations? ![-2x+4y=8, 2x+4y=32](https://tex.z-dn.net/?f=-2x%2B4y%3D8%2C%202x%2B4y%3D32)
Comparing given equations we came to know that equation(1) is divided by 2 to get the new equation i.e
![-4x+8y=16\\Divide\,\,by\,\,2:\\-2x+4y=8](https://tex.z-dn.net/?f=-4x%2B8y%3D16%5C%5CDivide%5C%2C%5C%2Cby%5C%2C%5C%2C2%3A%5C%5C-2x%2B4y%3D8)
While second equation is same as given.
So, The equation (1) is divided by 2 to create new equivalent system of equations.

let's recall that there are 180° in π radians, thus
![\bf \begin{array}{ccll} degrees&radians\\ \cline{1-2} 180&\pi \\ -36&x \end{array}\implies \cfrac{180}{-36}=\cfrac{\pi }{x}\implies -5=\cfrac{\pi }{x}\implies x=\cfrac{\pi }{-5}\implies x=-\cfrac{\pi }{5}](https://tex.z-dn.net/?f=%5Cbf%20%5Cbegin%7Barray%7D%7Bccll%7D%20degrees%26radians%5C%5C%20%5Ccline%7B1-2%7D%20180%26%5Cpi%20%5C%5C%20-36%26x%20%5Cend%7Barray%7D%5Cimplies%20%5Ccfrac%7B180%7D%7B-36%7D%3D%5Ccfrac%7B%5Cpi%20%7D%7Bx%7D%5Cimplies%20-5%3D%5Ccfrac%7B%5Cpi%20%7D%7Bx%7D%5Cimplies%20x%3D%5Ccfrac%7B%5Cpi%20%7D%7B-5%7D%5Cimplies%20x%3D-%5Ccfrac%7B%5Cpi%20%7D%7B5%7D)
