Answer:

Generally, the algebraic expression should be any one of the forms such as addition, subtraction, multiplication and division. To find the value of x, bring the variable to the left side and bring all the remaining values to the right side. Simplify the values to find the result.

I don’t know dawg sorry g

Please help. Which graph represents a function? I think a.

drek231 [11]

graph B ( the lower one )

for a function to be defined there can only be one value of y for each value of x

graph A has more than 1 value of y for given values of x

for example ( - 1, 4 ) and ( - 1, - 4 ) thus is not a function

graph B only has 1 value of y for a given value of x thus is a function

Suppose the postal service charges $10.30 per pound on the package shipped to England what is this rate in dollars per ounce

frosja888 [35]

Given:

The postal service charges $10.30 per pound on the package shipped to England.

To find:

The rate in dollars per ounce.

Solution:

We know that,

1 pound = 16 ounce

1 Dollar per pound = $\dfrac{1}{16}$ dollar per ounce.

1 Dollar per pound = 0.0625 dollar per ounce.

We have, the postal service charges $10.30 per pound on the package shipped to England.

Using the above conversion, we get

$10.30 Dollar per pound = $10.30\times 0.0625
$ dollar per ounce

$10.30 Dollar per pound = $0.64375
$ dollar per ounce

Therefore, the required rate is $0.64375 per ounce.

Line PQ passes through the points P(-5,-13) and Q(5,17) what is the equation of line PQ in standard form

PSYCHO15rus [73]

Answer:

$3x - y = - 2$

Step-by-step explanation:

The given line PQ passes through the points P(-5,-13) and Q(5,17) .

Find the slope using the formula:

$m = \frac{y_2-y_1}{x_2-x_1}$

Plug in the points to get:

$m = \frac{17 - - 13}{5 - - 5}$

$m = \frac{30}{10}$

$m = 3$

Use the point-slope formula :

$y-y_1 = m(x - x_1)$

Substitute the point (5,17)

$y - 17 = 3(x - 5)$

Expand:

$y - 17 = 3x - 15$

The standard form is when the equation is put in the form

$ax + by = c$

Regroup the terms to get:

$3x - y = - 17 + 15$

The standard form is

$3x - y = - 2$
