12. Write the equations in point-slope form of the line that passes through
the given points. (3,1) and (-5,2). *

Answer:

Step-by-step explanation:

So...

you would add -4 and -2 1/2 giving the total of -6 1/2.

All thats left is for you to graph it:)

Answer:

-4 - 2.5 = -6.5

Step-by-step explanation:

We are taking a Negative 4 (-4) and subtracting it by 2/5 (Minus 2,.5 or - 2.5).

This results us with -6.5

The arrow would be placed on the mark in between the -7 and -6 going RIGHT. ->

Answer:

a. The slope of EK is [tex]\frac{1}{2}[/tex]

b. The equation of line EK is y = [tex]\frac{1}{2}[/tex] x -  [tex]\frac{3}{2}[/tex]

Step-by-step explanation:

The form of the equation of a line is y = m x + b, where

The rule of the slope is m = [tex]\frac{y2-y1}{x2-x1}[/tex] , where

∵ BECK is a rhombus

∵ The diagonal is the line that joins two opposite vertices

∵ B and C are opposite vertices in the rhombus

∵ E and K are opposite vertices in the rhombus

∴ BC and EK are the diagonals of the rhombus BECK

∵ The diagonals of the rhombus are ⊥ and bisect each other

∴ EK is ⊥ bisector to BC

→ Let us find the slope and the mid-point of BC

∵ B = (3, 5) and C = (7, -3)

∴ x1 = 3 and y1 = 5

∴ x2 = 7 and y2 = -3

→ Substitute them in the rule of the slope above to find it

∵ m = [tex]\frac{-3-5}{7-3}[/tex] = [tex]\frac{-8}{4}[/tex] = -2

∴ m = -2

∴ The slope of BC = -2

→ To find the slope of EK reciprocal the slope of BC and change its sign

∴ m⊥ = [tex]\frac{1}{2}[/tex]

∴ The slope of EK = [tex]\frac{1}{2}[/tex]

a. The slope of EK is [tex]\frac{1}{2}[/tex]

→ Substitute the value of the slope in the form of the equation above

∵ y = [tex]\frac{1}{2}[/tex] x + b

→ To find b substitute x and y in the equation by the coordinates

   of a point on the line

∵ The mid-point of BC is the mid-point of EK

∵ The mid-point of BC = ([tex]\frac{3+7}{2},\frac{5+-3}{2}[/tex]) = ([tex]\frac{10}{2},\frac{2}{2}[/tex]) = (5, 1)

∴ The mid-point of EK = (5, 1)

→ Substitute x by 5 and y by 2 in the equation

∵ 1 =  [tex]\frac{1}{2}[/tex](5) + b

∴ 1 =  [tex]\frac{5}{2}[/tex] + b

→ Subtract  [tex]\frac{5}{2}[/tex] from both sides

∴  [tex]-\frac{3}{2}[/tex] = b

→ Substitute the value of b in the equation

∵ y = [tex]\frac{1}{2}[/tex] x + [tex]-\frac{3}{2}[/tex]

∴ y = [tex]\frac{1}{2}[/tex] x -  [tex]\frac{3}{2}[/tex]

b. The equation of line EK is y = [tex]\frac{1}{2}[/tex] x -  [tex]\frac{3}{2}[/tex]

Answer:

The relation represented by diagram 4 is NOT a function.

Step-by-step explanation:

To tell if a relation is not a function, pay attention to the x-intercepts. If there is more than one y-intercept with the same x-intercept, then it is not a function, because a function can only have one output (y-value) for each input (x-value).

According to the fourth diagram, the domains include 1, 2, and 3 while the range includes A, B, and C. Also, the ordered pairs would go as follows according to the arrows:

(1, A), (2, A), (2, B), (3, C)

While the y-values, A and B, are different, they share the same input, 2. Therefore, the relation represented by the 4th diagram is NOT a function.

Hope this helps!

Answer:

4 x ^2 ( x + 3 )

Step-by-step explanation:

The least common multiple (LCM) of two or more non-zero whole numbers is the smallest whole number that is divisible by each of those numbers. In other words, the LCM is the smallest number that all of the numbers divide into evenly.

Answer:

9 1/9

Step-by-step explanation:

Least Common Denominator is 18.

4 7/9= 4 14/18

1 5/6= 1 15/18

2 1/2= 2 9/18

4 14/18+ 1 15/18+ 2 9/18= 7 38/18

38/18= 19/9

19/9= 2 1/9

7+2 1/9= 9 1/9

Answer:

y-intercept = -5, slope = 5/3

Step-by-step explanation:

The y-intercept is where on the y-axis (vertical line) does the graph cross. The slope can be found many different ways. My method for this graph was simply counting up the graph until I got to the point where the graph crosses another whole number on the x-axis and then counted over. This makes sense because slope is rise over run so if you go up 5 (from the y-intercept) and then over 3 (to get to the next whole number point) then your slope is 5/3

If I am correctly understanding the question, I think the length of the line segment would be 4AB

Step-by-step explanation:

25% = 1/4

AB = 1/4

100% = 4/4

AB*4 = 4AB

Multiply AB by 4 to find the value that 100% would equal, resulting in 4AB.
