Find the slope of a line parallel to the line that crosses ( 3 , − 2 ) and the y -intercept is ( 0 , − 3 ) . I finally figured o

mamaluj [8]

Answer:

y = 1/3x - 3

Step-by-step explanation:

We can find the equation of the line, by finding the slope and combine with our y-intercept (-3).

We need to use the slope formula to find the slope.

Thus, we have (-3 - (-2)) / 0 - 3 = -1/-3 = 1/3

So our equation is y = -1/3x - 3

A triangle has vertices A(1, 1), B(2, 4), and C(4, 2). Line p is parallel to side AB and contains point C.

kenny6666 [7]

Answer:

$p:y = 3x-10$

Step-by-step explanation:

We are given the following in the question:

A(1, 1), B(2, 4), C(4, 2)

i) Slope of AB

$A(1, 1), B(2, 4)\\\\m = \dfrac{y_2-y_1}{x_2-x_1}\\\\m = \dfrac{4-1}{2-1}=3$

Thus, slope of AB is 3.

ii) Point slope form

The point slope form of a line can be written as:

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

The point intercept form of line can be written as:

$y = mx + c$

The line is parallel to AB and contains point C(4, 2). Since line p is parallel to AB, line p will have the same slope as line AB

Putting values, we get,

$y - 2 = 3(x-4)\\y = 3x-12+2\\y = 3x-10$

which is the required slope intercept equation of line p.

Use this expression to name each item. 7m3 + 6r2 – 3r - 8

Vitek1552 [10]

Answer:

In the given expression $7m^3 + 6r^2 - 3r - 8$

Variables = m, r

Coefficients = 7, 6 and -3

constant= -8

Step-by-step explanation:

We are given the expression $7m^3 + 6r^2 - 3r - 8$

We need to give variable, coefficients and constant.

Variable: The value of variable may change. It can be represented by x, y or any other letter

Coefficients: A numerical or constant quality that is placed with the variable. For example in 4x, 4 is coefficient

Constant: It is fixed value. It cannot be changed.

So, in the given expression $7m^3 + 6r^2 - 3r - 8$

Variables = m, r

Coefficients = 7, 6 and -3

constant= -8

Please help!!!! BRAINLIEST for whoever is correct!! What is the difference of the rational expressions below?

Nostrana [21]

Answer:

<h2> $\frac{3x + 25}{5 {x}^{2} }$ </h2>

Step-by-step explanation:

$\frac{x + 5}{ {x}^{2} } - \frac{2}{5x}$

Write all the numbers above the least common denominator ${5x}^{2}$

$\frac{5(x + 5) - 2x}{5 {x}^{2} }$

Distribute 5 through the parentheses

$\frac{5x + 25 - 2x}{5 {x}^{2} }$

Collect like terms

$\frac{3x + 25}{5 {x}^{2} }$

Hope this helps...

Good luck on your assignment...

Margie babysits for two families. Mr. and Mrs. Smith pay her $6.50 an hour to babysit their son, Shea. Mr. and Mrs. Jones pay Ma

rodikova [14]

Answer:

A) $\$ 6.5\timesx$ is the expression to represent total amount of money she earns babysitting for Smith family.

B) $\$45.5$ she will earn for Smith family for 7 hours

C) It would take $12 \ hrs$ for Margie to make $\$78$ when babysitting for the Smith family

Step-by-step explanation:

Given.

Mr. and Mrs. Smith pay Margie $\$6.50$ an hour to babysit their son, Shea.

Mr. and Mrs. Jones pay Margie $8 an hour to babysit their children, Sarah, Susan, and Dawn.

Let x be number of hours.

Solving for Part A.

Amount of Money earn from Smith family = Pay per hour $\times$ Number of hours = $\$ 6.5 \times x= \$ 6.5x$

Solving for Part B.

x=7

Margie earns from smith family for 7 hours = $\$ 6.5x=\$6.5\times7=\$45.5$

Solving for part C.

Margie earned = $\$ 78$

To find number of hours

No of hour Margie has done babysitting for Smith family $x=\frac{\$78}{\$6.5}=12 \ hrs$
