Answer:
-4n2+24n-9
Step-by-step explanation:
multiply each term by -4 to get -4n2+24n-9
The second and third functions both decrease with a slope of -4, but the second fiction has a y intercept of -3 and the third has a y intercept of +3. The first and fourth functions are both increasing with a slope of positive 4. The first one has a y intercept of -3, but the fourth has a y- intercept of -3. all of the functions are linear.
it helps to write all as equations
6.43 rounded to the nearest tenth is 6.40
The place after the decimal is the tenths place. We rely on the value of the hundredths place to know whether we round it up or we round it down to the nearest tenths. If the number is 5 and above, we round it up. If the number is below 5, we round it down.
3 is below 5 therefore from 6.43 we round it down to 6.40
