Answer:
23
Step-by-step explanation:
2m+ 3n First substitute the letters with numbers
=(2*4)+(3*5) DO the parentheses
=8+15 Add
=23
(4, -4) is the answer
-45<span>° is in quadrant IV and the point (4, -4) is the only point out of the points given that is also in quadrant IV</span>
Here, to find the average rate of change, you would simply divide 270 by 63. And when that is done, you would get a long decimal. 4.285714285714286
And since you obviously can't put in such a long decimal as your answer, you would round it instead. Once rounded, you would end up with 4.29 (because the number after 8 is five, which rounds up, which would turn the 8 to 9.)
Answer:
90
Step-by-step explanation:
There are 12 inches in a foot.
So you will take the 7 feet and multiply it by 12
This gives you 84 inches
You then take the 6 inches over the 7 feet and add to the 84 inches
Thus you get 90 inches.
If the snail keeps moving at this rate it will take the snail 2.23 minutes to reach 6.987 inches
