Answer:
x=1 y=1
Step-by-step explanation:
Let's use the elimination method. 3x+4y=72x-y = 1 (multiply both sides by 4)8x-4y=43x+4y=7
(add both equations together)11x=11x=1Plug x=1 into either of the equations2(1) - y=12-y=12=1+yy=1
I say B it intercepts both axis
w=4
adding a negative is like subtracting so w=11-7
65-79= -14
That being said...
-17+3= -14
Answer:-80
Step-by-step explanation:f(x)=2*2+4*-10
