What is the slope of the line that contains the points (7, -3) and (-7, 4)?

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

$m = \dfrac{-3 - 4}{7 - (-7)}$

$m = \dfrac{-7}{14}$

$m = -\dfrac{1}{2}$

Answer: The slope is -1/2.

Slope = (y2-y1)/(x2-x1) = (4-(-3))/(-7-7) = 7/(-14)= -1/2 or -0.5

time = 3 hr/job ; rate = 1/3 job/hr
Equation:

PLEASE HELP ME!!!!!!!!

GREYUIT [131]

Answer:

The solution to the system of equations (x, y) = (2, 4) represents the month in which exports and imports were equal. Both were 4 in February.

Step-by-step explanation:

We're not sure what "system of equations" is being referenced here, since no equations are shown or described.

Perhaps your "system of equations" is ...

f(x) = some equation

g(x) = some other equation

Then the solution to this system of equation is the pair of values (x, y) that gives ...

y = f(x) = g(x)

If x represents the month number, then the solution can be read from the table:

(x, y) = (2, 4)

This is the month in which exports and imports were equal. Both numbers were 4 in February.

Which of the following shows the best communicative property of addition ?

kumpel [21]

Answer:

In the given options, 4+5 = 5+4 shows the best commutative property.

Step-by-step explanation:

One of the properties that can be applied on numbers is commutative property. Commutative property states that the order of the numbers on which any operation is being performed, can be swapped and the answer won't change.

Commutative property can be applied on addition, subtraction and multiplication.

<u>Commutative property of Addition:</u>

Commutative property of addition states that changing the order of adding two numbers does not change the result i.e. a+b = b+a

In the given options, 4+5 = 5+4 shows the best commutative property.

given the midpoint and one endpoint of a line segment, find the other endpoint. endpoint: (4, 10) midpoint: (5, 9)

GalinKa [24]

The answer is (6, 8).

EXPLANATION

If you are given two numbers, you can find the number exactly between them by averaging them, by adding them together and dividing by two. The Midpoint Formula works exactly the same way. If you need to find the point that is exactly halfway between two given points, just average the x-values and the y-values.

That is:

$( \frac{x1 + x2}{2}. \frac{y1 + y2}{2} )$

But since the midpoint is given, we'll work this out in a different way.

To find the x of the other endpoint or x2, we'll have first to plug-in the given x values in the midpoint and x1.

So,

$m = \frac{x1 + x2}{2} \\ 5= \frac{4 + x2}{2}\\ 10= 4 + x2 \\ x2 = 6$

Now, let's proceed to y2.

$m = \frac{y1 + y2}{2} \\ 9= \frac{10 + y2}{2}\\ 18= 10 + y2 \\ y2 = 8$

So now you have the x and y values of the other endpoint: (6,8).
