Answer:
<h2>B. 2x + y = 4</h2>
Step-by-step explanation:
Having the system of equations in its simplest form
![\left\{\begin{array}{ccc}ax+by=c\\dx+ey=f\end{array}\right](https://tex.z-dn.net/?f=%5Cleft%5C%7B%5Cbegin%7Barray%7D%7Bccc%7Dax%2Bby%3Dc%5C%5Cdx%2Bey%3Df%5Cend%7Barray%7D%5Cright)
If
![a=d,\ b=e,\ c=f](https://tex.z-dn.net/?f=a%3Dd%2C%5C%20b%3De%2C%5C%20c%3Df)
then the system of equations has infinitely many solutions.
If
![a=d,\ b=e,\ c\neq f](https://tex.z-dn.net/?f=a%3Dd%2C%5C%20b%3De%2C%5C%20c%5Cneq%20f)
then the system of equations has no solution.
If
![a\neq d\ or\ b\neq e](https://tex.z-dn.net/?f=a%5Cneq%20d%5C%20or%5C%20b%5Cneq%20e)
then the system of equations has one solution.
We have the equation
![y=-2x+4](https://tex.z-dn.net/?f=y%3D-2x%2B4)
Convert to the standard form Ax + By = C<em>:</em>
<em />
<em> add 2x to both sides</em>
![y+2x=-2x+2x+4\\\\2x+y=4](https://tex.z-dn.net/?f=y%2B2x%3D-2x%2B2x%2B4%5C%5C%5C%5C2x%2By%3D4)
Answer:
123
Step-by-step explanation:
In a parallelogram, both pairs of opposite angles are congruent. Also, both pairs of opposite sides are parallel, meaning there are consecutive interior angles. Consecutive interior angles equal 180, so simply subtract 57 from 180 to find your missing angles.

answer
6:15:16
step-by-step explanation
the ratio of stars to hearts to circles is stars:hearts:circles
plug in 6 for stars, 15 for hearts, and 16 for circles
6:15:16
since these do not have a common factor, this is your final answer
