I have it please like me or whatever
-4x+y= -9 can be turned into
y= -9 + 4x
5x+2y=3 (plug y in)
5x+2(-9+4x)=3
5x-18+8x=3
5x+8x=3+18
13x=21
divide 13 on both sides
x=1.6
Sec is the length of the hypotenuse divided by the length of the adjacent side.
Meaning divide 20/16
Meaning your secant or sec is 1.25 or 1 1/4
Answer:
First, you have to rewrite the question in a way to isolate your Y. This means moving the -3 over to the other side.
Y = 2(x+1) + 3
Now, you should multiply the 2 out in the parenthesis.
Y=2x+2+3
Now, combine like terms! In this case, your like terms are 2 and 3.
Y=2x + 5
Because there are no more like terms, and Y is completely isolated, Y=2x + 5 is your answer!
