Answer:

x = -41/14

Step-by-step explanation:

7(2x+6)=1

Distribute

14x +42 =1

Subtract 42 from each side

14x+42-42 = 1-42

14x = -41

Divide each side by 14

14x/14 = -41/14

x = -41/14

Answer:

x=-\dfrac{41}{14}

Step-by-step explanation:

7(2x+6)=1

Expand parentheses:

14x+42=1

Subtract 42 from both sides:

14x=-41

Divide both sides by 14:

x=-\dfrac{41}{14}

Hope this helps!

Calculate the account balance for $800 left on deposit for 255 days earning 5.25% compounded daily.
Svetradugi [14.3K]
The value would be 829.89.

The formula we use is 

A=p(1+\frac{r}{n})^{nt},

where A is the total amount, p is the principal, r is the rate expressed as a decimal number, n is the number of times per year the interest is compounded, and t is the number of years. 

We will use 800 for p; 5.25/100 = 0.0525 for r; 365 for n; and (255/365) for t (since it is not a full year):
A=800(1+\frac{0.0525}{365})^{\frac{255}{365}\times365}
\\
\\=800(1+\frac{0.0525}{365})^{255}=829.89

what proteins embedded in the phospholipid bilayer do what in the cell membrane? A) organize amino acids for protein synthesis B
ohaa [14]

Answer: The answer is (D) prevent the passge of certian molecules into the cell.

Step-by-step explanation: We have four option out of which one describes the functions of protein present in the phospholipid bilayer in the cell membrane.

Phospholipid bilayers are critical components of cell membranes. Its function is to act as a barrier to the passage of molecules and ions into and out of the cell. It allows selective substances and molecules to come in and go out of the membrane.

Thus, the correct option is (D).

After plotting all the three points, we get the parabolic equation in the form is 2(x - 1)²-34.

<h3>What is parabola?</h3>

Any point on a parabola, which has the shape of a U, is situated at an equal distance from the focus, a fixed point, and the directrix, a fixed line.

General equation of the quadratic equation,

Y = ax² + bx +c

Given points,

(-2, 0),

(-1, -10),

(4, 0).

Putting the points in the general equation,

Putting (-2, 0), we get

0 = 4a - 2b + c

Putting (-1, -10), we get

-10 = a - b +c

Putting (4, 0), we get

0 = 16a + 4b +c

Solving all equations we get,

a = 2 , b = -4 , c = -16

After putting the values,

Y = 2x²- 4x- 16

2(x² - 2x - 8)

2(x²- 2x + 1 - 1 - 16)

=2(x - 1)²-34

Hence we get the required equation in the parabolic form.
