Answer: A
Step-by-step explanation:
If you put 0 in for x, then you would be dividing by 0. Dividing by 0 is always undefined.
Neither one will ever hit the axis I think? if its x=3.5 then its horizontal but its above the x axis. Same with the second one. its vertical and will never hit the y axis. Not sure how to write that into those boxes but I think there isn't an intercept.
This is the answer...
y=250-25x
y=30+30x
<span>2(a+b)=c
2a + 2b = c
2b = c - 2a
b = (c - 2a)/a
answer
</span><span>D. b = (c−2a)/2 ; distribute 2 to get 2a+2b, subtract 2a, then divide by 2.</span>
Yes because 84+45 is 129 and 3(28+15) is 129
