I believe it is A.
Option A is of two variables x & y and it is a straight line graph.
2x - 5 = y
F(x) = -4 means y = -4. That means whatever the x is, the answer is going to be -4.
Answer:
x = (180 - 68) / 2
Step-by-step explanation:
x = 56°
X+y=17 solve for a variable and plug into the 2nd equation
(x+3)/y=1 also could be written as x+3=y
x=17-y
17-y+3=y combine and add y over to other side
20=2y
y=10
plug back in x+10=17
x=7
so the original fraction is 7/10
