Answer:Its B
Step-by-step explanation:
I just took the test
i think the second one would be the best estimate.
the rule for rounding is 5+ you would go up and 4 below you would round down, so:
221 -> 200
485 -> 500
562 -> 600
833 -> 800
therefore, 200+500+600+800 is the answer
Answer:
(3.6, 0), (0, -2)
Step-by-step explanation:
To find the y-intercept, set x=0:
-5·0 +9y = -18
y = -18/9 = -2
To find the x-intercept, set y=0:
-5x +9·0 = -18
x = -18/-5 = 3.6
The intercepts are ...
x-intercept: 3.6
y-intercept: -2
