To solve this system of linear equations we need a little trick called elimination steps are below
we are given the following system of equations


if you look at the x variables in both equations you can see that we can easily eliminate them by multiplying the bottom equation by -4 as so


simplify and we get


now we can combine like terms on each side with the x's cancelling and get

now divide off -35

great now we can go back to our original system and pick a equation and substitute y back in to find x lets use

so now we substitute y and get




now we put x and y into one coordinate (x,y)
so now our FINAL ANSWER IS
(-17,-1)
the standard form of that graph is ax squared +bx+c
Answer:
Side FE < Side DE < Side DF
Step-by-step explanation:
The traditional approach here is to solve x - 5y = -5 for y and then read off the coefficient of x (which is the desired slope):
-5y = -5 - x, or
5y = 5 + x
Then y = (1/5)x + 1. The slope is (1/5).
3pi/2 is the same as 270°, so theta is less than 270°, and the numerators of sin and cos are opposite with denominators the same, the answer is A
