Which of the following ordered pairs is a solution of x + 1/2y = 1?

pogonyaev

(-2,6)

for example

x+1/2y=1

the ordered pair i will use is the first one. (-2, 6)

(-2) + 1/2(6)=1

from there it is a simple add/subtract and multiply/divide math problem.

1/2(6)=3

(-2) + 3 = 1

yes this ordered pair works for the solution meaning it is the answer.

Fran is going to transfer her credit card balance over to a new card. She has an existing balance of $752.69. Her current card c

Elina [12.6K]

Answer:

Fran's balance will be $866.73.

Step-by-step explanation:

She has an existing balance of $752.69

Her current card charges her a transfer fee of 12.5%, added to her balance, for transferring her debt.

This becomes: $0.125\times752.69=94.08$

Total is : $752.69+94.08=846.77$

The new card has an opening fee of $50, which is also added to her balance.

This becomes now = $846.77+50=896.77$

She will also have to make an immediate minimum payment, which is 3.35% of her total balance.

This amount is = $0.0335\times896.77=30.04$

Now balance in her account is = $896.77-30.04=866.73$

So, Fran's balance will be $866.73.

Plzzzzz help will Mark BRAINLYLIST!!!!!

Serga [27]

Answer:

104 units

Step-by-step explanation:

One key thing to note about a reflection is that side lengths and angle measures will always remain the same on the reflected figure. With that in mind, let's note the side lengths in both the original and reflected figures.

$AB=\\BC=20\\CD=30\\AD=$

$A'B'=22\\B'C'=\\C'D'=\\A'D'=32$

Remember, since side lengths are the same, let's fill in the missing values with the values of the side lengths given in each of the figures:

$AB=22\\BC=20\\CD=30\\AD=32$

$A'B'=22\\B'C'=20\\C'D'=30\\A'D'=32$

See? Notice how the values are the same! To find the perimeter ( $P$ ) of a quadrilateral, we have to add each side length:

$P=22+20+30+32$

Solve:

$P=104$

Select the correct answer. The capacity in cubic feet of a cylindrical silo is given by the function C(x), where x is the radius

katrin [286]

Answer:

C. H(x) = 2x+6

Step-by-step explanation:

Volume of the cylindrical silo = Area of its circular base × Height

Volume of the cylindrical silo = πr²×H

If the area of the circular base of the silo is given by the function A(x), the volume is given by C(x) and the height is given by H(x), the formula can be expressed as;

C(x) = A(x) × H(x)

The height of the cylindrical silo will be;

H(x) = C(x)/A(x)

Given C(x) = 6.28x³ + 18.84x² and

A(x) = 3.14x²

H(x) = 6.28x³ + 18.84x²/3.14x²

H(x) = x²(6.28x+18.84)/3.14x²

H(x) = (6.28x+18.84)/3.14

H(x) = 3.14(2x+6)/3.14

H(x) = 2x+6

Hence, the function, H(x) that represents the height of the silo is 2x+6.
