so uh who knows this??!

Answer:

additive inverse property

Step-by-step explanation:

(x)+(-x)=0

The additive inverse property states

a+ -a =0

Answer:

The absolute property.

Step-by-step explanation:

A number plus the opposite of the number will always equal 0.

Answer:

13.5 ounces of silver is worth $272.16

Step-by-step explanation:

since it is $20.16 per ounce, simply multiply 20.16 and 13.5 to get 272.16

Step-by-step explanation:

Times 20.16 by 13.5 and you will get 272.16

Answer:

4

Step-by-step explanation:

The square of 100 means that 100 is being multiplied by itself. So the square of 100 is 100x100 = 10,000

Whenever you multiply a number by a multiple of 10, you simply add the number of 0s onto the end of the original number, so 100 originally has 2 zeros, so multiplying by 100 will add on another 2 zeros.

So, the number 10,000 which is the square of 100 has 4 zeros.

At starting hot-air balloon starts 6 feet.

So, at t = 0 , h = 6 feet.

Now, distance travelled per minute is 20 feet.

So, extra distance travelled in t minutes is 20t feet.

Now,

Total height = Staring height + increase in height w.r.t time.

h = 6 + 20t

Therefore, the height h in feet as a function of time t in minutes is h = 6 + 20t .

Hence, this is the required solution.

Answer:

n = m - a

Step-by-step explanation:

Given that:

The expression of the formula  a = m - n

where;

a = actual cost of an item

m = original price

n = amount of coupon in dollars

The objective is to solve for the amount of the coupon.

In order to determine the amount of the coupon, we need to make n which is the amount of coupons in dollars the subject of the formula from the given expression.

So if a = m - n

a + n = m

n = m - a

I'm sorry if this is incorrect, but I think the answer is [tex]-2, \sqrt{5}, 4, 3^2[/tex]

Explanation: A negative number will always be the least. 3 squared is actually 3*3 and that would be 9. The square root of 5 is 2.2360679775 which is less than 4 so that would go in the second place. I hope this makes sense! :)

Answer:

Option (1)

Step-by-step explanation:

Planes ZWV (shaded side) and plane TUV (Top of the box) are the two sides of the given cube or box in the picture attached,

Common edge of the given planes is side SV.

Common edge or the line where two planes meet is the line of intersection of two planes.

Therefore, line SV will be the line of intersection of the given planes.

Option (1) will be he answer.

Answer:

The answer is

Step-by-step explanation:

Area of a circle is given by

where r is the radius of the circle

From the question

r = 7 inches

So the area of the circle is

A = 3.14(7)²

= 3.14 × 49

We have the final answer as

Hope this helps you

Here, we are given with a circle whose radius = 7 inches, and we are asked to find the area of the circle. Taking value of π = 3.14

We know,

Here,

So, let's find the area,

➝ Area of the circle = πr²

➝ Area of the circle = 3.14 × 7²

➝ Area of the circle = 3.14 × 49

➝ Area of the circle = 153.86 inch²

Hence, Area of the circle:

[tex] \huge{ \boxed{ \bf{153.86 \: {inch}^{2} }}}[/tex]

And we are done !!

Answer:

-x² + 2x + 8

Step-by-step explanation:

Essentially we need to subtract g(x) from f(x):

(f - g)(x) = f(x) - g(x) = (2x + 1) - (x² - 7)

Distribute the negative:

(2x + 1) - x² - (-7) = (2x + 1) - x² + 7

Combine like terms:

2x + 1 - x² + 7

-x² + 2x + 8

Thus, the answer is -x² + 2x + 8.

Answer:

I think ot a it been awhile sense I did algebra

Answer:

C

Step-by-step explanation:

2x +4 > 16

If you plug in 6 where the x is, and multiply 2 by 6, you get 12. Add 4 to 12 to get 16. If x is 6 it equals 16, so if x > 6 the answer will be more than 16.

Answer: 4.5

Step-by-step explanation:

To evaluate ab - 0.50, we want to plug in the given values for a and b and then solve.

(1)(5)-0.5                       [multiply]

5-0.5                             [subtract]

4.5

After plugging in the values of a and b, we found that the solution is 4.5.

Step-by-step explanation:

subtract 5x from 7x

subtract 4 from 10

divide 2x and 6 by 2

Answer:

x=3

Step-by-step explanation:

7x +4 =5x +10

7x - 5x =10 - 4

2x =6

x=6 :2

x=3

7 ×3 +4 =5 ×3 +10

21 +4 =15 +10

25 =25
