Answer:

Square root of 40, I don't know what the brace is

Step-by-step explanation:

To find side c, you have to use the Pythagorean theorem. A^2+B^2=C^2. In this case A and B are 6 and 2. This means the equation would be 6^2+2^2=C^2. Simplify this to get 36+4=C^2. Add 36 and 4 to get 40. 40=C^2. This would mean that it is square root of 40.

Answer:

2. -8x - 6

3. 4.5x + 10 (I think, not quite sure)

4. 0.25 - 5x (I think, also not quite sure)

5. -8x - 5y + 5.5

Step-by-step explanation:

2. Distribute the -2 to all terms except -1.

-2(4x + 2.5) - 1

-8x - 5 -1

-8x - 6

5. Combine 6x and -14x (6 - 14 = -8).

6x - 5y - 14x + 5.5

-8x - 5y + 5.5

Answer: C

Step-by-step explanation: I took the test

Answer:

Step-by-step explanation:

Area of a square = 49a⁸b¹⁰

  Side = √49a⁸b¹⁰

           = √7²*(a⁴)²*(b⁵)²

          = (7a⁴b⁵)²

Side = 7a⁴b⁵

Answer:

42

Step-by-step explanation:

So you basically replace the x with 2. So f(x) = x21, then it would change to f(2) = 2(21). Then you would just multiply 21 by 2 and you would get 42.

Hope this helps!

Answer:

a) Braxton's initial investment is equals to (=) Pam's initial investment.

b)The interest on Braxton's account is less than (< ) the interest on Pam's

   account.  

Step-by-step explanation:

Given - Braxton has money in a savings account. The equation

            B = [tex]800(1 + 0.03)^{t}[/tex] can be used to calculate the amount of money    

            in dollars, B, Braxton has in his account after t years since opening

             the account.  Pam also has money in a savings account. The  

            equation, P= [tex]800(1 + 0.04)^{t}[/tex]  can be used to calculate the  amount of  

             money in dollars, P, Pam has in her account after t years since  

              opening the account.      

To find - a) Braxton's initial investment ..........Pam's initial investment.

                b) The interest on Braxton's account .....the interest on Pam's

                    account.

Proof -

As given, Broxton equation is -  

                 Pam equation is -    

Now,

a.)

For initial investment , Put t = 0

⇒B = [tex]800(1 + 0.03)^{0} = 800(1) = 800[/tex]  

   P =  [tex]800(1 + 0.04)^{0} = 800(1) = 800[/tex]  

We can see that for  t = 0

Initial investment of Braxton = Initial investment of Pam

⇒Braxton's Initial investment = Pam's initial investment.

b.)

For the interest,

As we have not given any time period for which the interest has to be find.  

So , let the time period , t = 5 years

Therefore,

B = [tex]800(1 + 0.03)^{5} = 800(1.03)^{5} = 800(1.159) = 927.42[/tex]  

P = [tex]800(1 + 0.04)^{5} = 800(1.04)^{5} = 800(1.217) = 973.32[/tex]

Now,

Interest on Braxton's account = 927.42 - 800 = 127.42 ≈ 127

Interest on Pam's account = 973.32 - 800 = 173.32 ≈ 173

∴ we get

The interest on Braxton's account is less than the interest on Pam's account.

Answer:

change of scale and origin of the variable X and Y.

Answer:

2x=50

Step-by-step explanation:

Hi there,

Your question is "twice a number (x) is fifty"

Recall how a number is represented by x.

Twice a number would be represented as 2x.

Therefore, to represent that twice a number is equal to 50, that would result in the expression: [tex]2x=50[/tex]

If you're looking to solve this equation, it's often best to think about the "reverse" of the current equation.

Notice how 2 is multiplying the x.

To isolate x, divide that side by 2.

However, recall that whatever is done to one side of an equation must also be done to the other side of the equation. Therefore, you will need to divide both sides by 2.

[tex]2x=50[/tex]

[tex]\frac{2x}{2} = \frac{50}{2}[/tex]

[tex]x=25[/tex]

Equation: [tex]2x=50[/tex]

Solving for x: 25

Hope that helps!

Answer:

she needs 3 1/3 more yards

Step-by-step explanation:

There are 3 feet in a yard

14yards x 3feet = 42 feet

58 feet- 42 feet= 10 feet

10 divded by 3 is about 3.3

Answer: 6 yards

Step-by-step explanation:

1)    14 x 3 = 42

2)    58 - 42 = 16

3)    16 / 3 = 5.33333333....

4)     round up = 6

The answer would be

A.) ~-12~

because 2-24=-22 -22+8+2=-12  

B.)~16~

because 6+8-8+10 and -8+8=0 so 6+10=16

Hope this helps

Answer:

-53 (answer : B)

Step-by-step explanation:

hello :

this the arithmetic sequence because :

(-9)-(-13)=(-13)-(-17)= 4  (common difference)

the first term is : A1 = -17

the nth term of an arithmetic sequence is :

An= A1 +(n-1)d   ....a common difference is : d

the 10th term is : A10

A10= -17 +(10-1)(4) = -17-36 = -53 (answer : B)
