Answer:

y+2x=9 is the line passing through (6,-3) parallel to y=-2x-5

Step-by-step explanation:

In the question we are given with a point (6,-3) and a line $y=-2x-5$ . we have to find the line passing through given point and parallel to given line.\

formula used: equation of a line passing through a point(a,b) with slope m is given by $(y-b) = m(x-a)$ .

here we have (a,b)=(6,-3) and the slope of the line is slope of $y=-2x-5$

i.e, -2( coefficient of x).

therefore, substituting point and slope in formula we get $y+3 = -2(x-6)$

which simplifies to $y+3= -2x+12\\ y+2x=9$ is asked line equation

Hi! I have a math question. This is a two part problem.

Mumz [18]

Answer:

Blair chosen to purchase shirt from company B. Given:

Each shirt costs 3.10$

Shipping cost is 4% (0.04) of total order.

=>Total cost without shipping: 150 x 3.10 = 465$

=> Total cost with 4% of shipping: 465 + 465 x 0.04 = 483.6$

=> Total cost Blair paid for one shirt: C = 483.6/150 = 3.22$

The markup is 75% of original cost:

=> Blair can multiply the total cost for one shirt by 0.75

Blair will sell shirt with price which is equal to the sum of total cost for one shirt and markup:

=> P = 3.22 + 3.22 x 0.75 = 5.64$

Hope this helps!

The outside temperature can be estimated based on how fast crickets chirp. At 104 chirps per minute, the temperature is 63 degre

Rasek [7]

Answer:

For 124 chirps per minute the temperature is 68 ºF.

For 68 chirps per minute the temperature is 54 ºF.

Step-by-step explanation:

Linear functions are those whose graph is a straight line. A linear function has the following form

$f(x)=b+mx$

b is the constant term or the y intercept. It is the value of the dependent variable when x = 0.

m is the coefficient of the independent variable. It is also known as the slope and gives the rate of change of the dependent variable.

We know that

At 104 chirps per minute, the temperature is 63 ºF.

At 176 chirps per minute, the temperature is 81 ºF.

This information can be converted to Cartesian coordinates (x, y). Where x = the number of chirps per minute and y = the temperature in ºF.

To find a linear function that let us find the outside temperature from how fast crickets chirp we must:

Find the slope:

$m=\frac{y_2-y_1}{x_2-x_1}=\frac{81-63}{176-104}=\frac{1}{4}$

Find the equation:

$81=\frac{1}{4}\cdot 104+b$

Solving for b

$b=81-\frac{1}{4} (176)=37$

Therefore, the linear function is

$y=\frac{1}{4} \cdot x+37$

Now, using this linear function we can know the temperature when we know the chirps per minute:

For 124 chirps per minute the temperature is:

$y=\frac{1}{4} \cdot (124)+37=68$

For 68 chirps per minute the temperature is:

$y=\frac{1}{4} \cdot (68)+37=54$

the sum of two numbers is-5.When twice the first number is added to the second number the result is -2,find the two numbers

juin [17]

Answer:

Step-by-step explanation:

First write the question as an equation

x+y = -5

2x+y = -2

From the given equations, we can create a third one.

x+y+2x+y = -7 or 3x+2y = -7

Use trial and error method for the possible values x and y

We know that at least one of these two have to be negative.

x can be 1, in which case y has to be 5.

Check this for

x+y ≠ -5

x can be -1

Try another one where x = -1 and y has to equal -2

Check this

x+y = -5

but,

2x+y ≠ -2

Another one,
