Step-by-step explanation:

one quarter of 9 is 2.25 cause if u divide 9 by 2, you get 4.50 which is one half, so if you divide 4.50 by 2 you get 2.25 which is one quarter of 9

Answer:

y=-4, x=8

Step-by-step explanation:

1)3x+5y=4

2)2x+3y=4

Make 1 and 2 have the same co-efficient of x or y (i chose x as it is easier to get to 6 then 15)

Label the 2 new equations as 3 and 4

3)6x+10y=8

4)6x+9y=12

Now we can take away to give

y=-4

Now we substitute this into 1 or 2

I chose 2:

2x+3(-4)=4

2x=4+12

2x=16

x=8

Answer:

x = 8

y = -4

Step-by-step explanation:

Multiply the first equation by 2:

⇒ 3x + 5y = 4  ⇒  6x + 10y = 8

(we will call this equation 3)

Multiply the second equation by 3:

⇒ 2x + 3y = 4  ⇒  6x + 9y = 12

(we will call this equation 4)

Subtract equation 3 from equation 4 to eliminate the x variable:

     6x + 9y = 12

-    6x + 10y = 8

              -y = 4

Therefore, y = -4

Substitute y = -4 into one of the equations and solve for x:

3x + (5 x -4) = 4

⇒ 3x - 20 = 4

⇒ 3x = 24

⇒ x = 8

Answer:

  f(x) = x^3

Step-by-step explanation:

To identify the parent function, replace any added constants with 0, and replace any constant multipliers with 1. Doing that gives you ...

  f(x) = 1·x^3 -0

  f(x) = x^3 . . . . . . the parent function

Answer:

maybe 5,5-6 foot. don't really keep track I just know they are almost as tall as me

Step-by-step explanation:

1 m (meter) is 100 cm (centimeters).

so, 7 m is 700 cm.

each piece is r × 2.54 cm long (as every inch is 2.54 cm).

so,

number of pieces = 700 / (r × 2.54)

The number of species can find by expression is

700 / (r × 2.54)

We have given that

Sophia has 7 m of ribbon

she will cut pieces of ribbon that are each r inches long.

We have to calculate the number of pieces of ribbon that she will have

What is the value of 1 meter in cementer?

1 (meter) =100 (centimetres).........(1)

multiply both side by 7

7 m is 700 cm.

each piece is

r × 2.54 cm long ..................(as 1 inch is 2.54 cm).

so,

[tex]number of pieces = 700 / (2.54r)[/tex]

Therefore the number of species can find by expression is

700 / (r × 2.54)

Answer:

aₙ= 1.5aₙ₋₁ with a₁= 3

Step-by-step explanation:

recursive formula is represented by aₙ=b· aₙ₋₁

The possible values of for a, k, and b from the graph of the function will be D. a=4, k=2, b= pi/4.

A function simply means a relation between the set of inputs and the outputs.

A function from set X to set Y assigns each element of X to Y. In this case, the set X is the domain while the set Y is the codomain.

From the graph attached, it can be seen that the values of for a, k, and b from the graph of the function will be a=4, k=2, b= pi/4.

Answer:

  (c)  r units right

Step-by-step explanation:

The translation transformations are ...

  g(x) = f(x -h) +k . . . . . . . shifts h units right and k units up

Your transformation has h=r and k=0, so the graph is shifted r units right and no units vertically.

_____

Additional comment

This in not terribly mysterious. Suppose you have f(1) = 6. This means the point (1, 6) is on the graph.

Now, suppose you transform this to ...

  g(x) = f(x -2)

When the value of x is 3, the value of g(x) is f(3-2) = f(1) = 6. That means the point (3, 6) is on the graph of g(x).

It is the same as the point (1, 6) on the graph of f(x), but shifted 2 units to the right.

__

You can shift a function r units right by replacing x with (x-r), as we just discussed. You can shift a function u units up by replacing y with (y-u). When we write equations in "functional form", the "u" gets "moved."

  y-u = f(x) . . . . . graph of f(x) shifted u units up

  y = f(x) +u . . . . graph of f(x) shifted u units up. (u added to both sides of the above equation)

Answer:

Step-by-step explanation:

The unpaid balance method is a common method used by credit card companies to calculate finance charges. It determines the finance charge based on a portion of the previous balance you have not yet paid.

Equations to use:

[tex]\boxed{\begin{minipage}{9.7cm}\phantom{w}\\Periodic (monthly) rate = annual interest rate $\div$ 12\\\\Finance Charge = previous balance $\times$ periodic rate\\\\Unpaid Balance = previous balance + finance charge +\\\phantom{wwwwwwwwwww} new purchases - returns - payments\\\end{minipage}}[/tex]

The periodic rate is the interest rate charged over a certain number of time periods. The interest on a credit card is usually calculated monthly, so if the annual interest rate is 21%, then the periodic (monthly) rate is:

[tex]\text{Periodic Rate}=\dfrac{21\%}{12}=1.75\%=0.0175[/tex]

The unpaid balance is "last month's balance", which is $385.

Calculate the finance change by multiplying the previous balance (last month's balance) by the periodic rate:

[tex]\begin{aligned}\text{Finance change} &=\rm previous\; balance \times periodic\;rate \\&=\$385 \times 0.0175 \\&= \$6.7375\end{aligned}[/tex]

Calculate the unpaid balance by subtracting the returns and payments from the sum of the previous balance, finance charge and new purchases:

[tex]\begin{aligned}\rm Unpaid \; Balance &= \rm previous\; balance + finance\;charge +new \;purchases\\&\phantom{=w}\rm - returns - payments\\&= \$385 + \$6.7375 + \$303 - \$158 - \$250 \\&= \$286.7375\end{aligned}[/tex]

Finally, to calculate the current month's finance charge, multiply the unpaid balance by the periodic rate:

[tex]\begin{aligned}\text{Current month's finance charge}&=\rm unpaid \;balance\times periodic \;rate\\&=\$286.7375 \times 0.0175 \\&= \$5.02\; \text{(nearest cent)}\end{aligned}[/tex]

Therefore, the current month's finance charge is $5.02 to the nearest cent.

Answer:

Bill's bar has 57.3 grams of cocoa.

Step-by-step explanation:

The math part that your question is asking is: What is 69% of 83?

In order to use the percent 69% in a calculation, you need to change it to a decimal.

69% is 0.69

You move the decimal to the left, two places.

69% is 69.% If you don't see a decimal to start with and it is a whole number, then the decimal is starting on the right.

Move it two places to the left, you get

.69

Now MULTIPLY.

.69 × 83

= 57.27

ROUND your answer to the nearest tenth. That means only one digit to the right of the decimal.

57.27 rounds to 57.3

Bill's bar has 57.3 grams of cocoa.

Answer:

Step-by-step explanation:

We know that, when combining 2q + 8q we'll get → 10q

1) q • 10 (Nope)

2) 10q (yes, It's equivalent)

3) q +9q (combine) → 10q (yes, It's equivalent)

4) q + q+ 8q (combine) → 10q ( yes, It's equivalent)

So therefore, 10q , q +9q, q + q+ 8q are expressions equivalent to 2q + 8q..
