Answer:

The opposite of 14 is -14.

Step-by-step explanation:

Opposites are numbers with the same distance from 0 but one is to the right of 0 and the other is to the left of 0.

The opposite of 0 is itself,0.

So the opposite of 5 is -5 since both 5 and -5 have the same distance from 0 and one is to the left and one is to the right of 0.

The opposite of 14 is -14 since both have the same distance from 0 and one is to the right and one is to the left of 0.

You can also think of this question as what can I add to 14 that will give me 0.

The answer is -14 since -14+14=0.

Another word for opposites is additive inverses. When you add additive inverses you get 0.

Another example: What is the opposite of -16?

The answer is 16 since 16+(-16)=0.

The what value complete the square for the expression x squared plus 16x

Troyanec [42]

Take the coefficient of the x-term, half it, then square that. add this to both sides

x² + 16x. coefficient of x is 16. half of 16 is 8. 8²=64

x² + 16x + 64 =64. this is your answer but to continue

x² + 16x + 64 = 64
(x+8)² = 64
x+8 = ✓64
x+ 8 = ±8
x = 0 or -16

Train travels at 3 hours if it's speed is 65 miles per hour. It takes the train 2.5 hours if it's speed is 78 per hour . Identif

seraphim [82]

Step-by-step explanation:

Let the original speed of the train be x km/h.

Time taken to cover a distance of 360 km = 360/x hours.

New speed of the train = (x+5) km/h.

Time taken to cover a distance of 360 km at new speed = 360/x+5 hours.

Since, the train takes 1 hour less time,

∴360/x - 360/ x+5 = 1

⇒360 (5) = x² + 5x

⇒1800 = x² + 5x

⇒x² + 5x - 1800 = 0

⇒x² + 45x - 40x - 1800 = 0

⇒x (x+45) - 40( x +45) = 0

⇒(x+45) (x-40) = 0

⇒x = (-45), 40

But since speed cannot be in negative.

∴x = 40 km/hr.

Hence, the original speed of the train is 40 km/h.

So, yearly $2100 is paid, plus the 1.73% interest, so 1.73% interest is $2136.33every year interest stacks on itself so youll take 1.73% of the year 1 total with interest.

Year 1 total: $2136.33

Year 2 total:$2173.29

Year 3 total:$2210.89

Year 4 total:$2249.14

Year 5 total:$2288.05

Total Paid After 5 years:$11057.70

Year 1 total interest:$36.33

Year 2 total interest:$36.96Year 3 total interest:$37.60Year 4 total interest:$38.25Year 5 total interest:$38.91

Total Interest paid after 5 years:$188.05

Match the average rates of change of f(x) with the corresponding intervals.

algol13

The average rate change of a function is given by the formula: $AG= \frac{f(x_{2})-f(x_{1})}{x_{2}-x_{1} }$
So lets apply our formula to each one of our intervals:

For [-4,-2]
$AV= \frac{-12-0}{-4-(-2)} =6$

For [-2,1]
$AV= \frac{0-3}{-2-1} =1$

For [-3,1]
$AV= \frac{-5-3}{-3-1} =2$

For [-4,0]
$AV= \frac{-12-4}{-4-0}=4$

We can conclude that you should fill your table as follows:
[-4,-2]----->6

[-2,1]----->1

[-3,1]----->2

[-4,0]----->4
