Please find the missing value in the ordered pairs.

lianna [129]

Answer:

a ) y = 2,

b ) x = 5,

c ) x = - 3,

d ) y = 4

Step-by-step explanation:

a )

$( - 3, - 4 ), ( 0, y )\\Slope = - 4 - y / - 3 - 0\\2 = - 4 - y / - 3,\\\\- 6 = - 4 - y,\\- y = - 2\\\\y = 2$

b )

$( - 2, 2 ), ( x, 5 )\\Slope = 2 - 5 / - 2 - x,\\3 / 7 = - 3 / - 2 - x,\\\\( Algebra ) x = 5$

c )

$( x, 5 ), ( 1, - 5 )\\Slope = 5 - ( - 5 ) / x - 1\\- 5 / 2 = 5 + 5 / x - 1,\\- 5 / 2 = 10 / x - 1\\\\( Algebra ) x = - 3$

d )

$( -6, y ), ( 8, 2 )\\Slope = y - 2 / - 6 - 8,\\- 1 / 7 = y - 2 / - 14\\\\( Algebra ) y = 4$

Hope that helps!

Answer: I need you to zoom in more on the paper.

The paper looks blurry and fuzzy to me.

Which angles form a linear pair?

Igoryamba

A linear pair of angles has a common side, and the vertex is on the line designated by the points denoting the non-common sides.

Consider the first choice:

... the common sided is RL, and the other two points are P and M. Point R (the vertex of the angles) is not on line PM. (In fact, line PM is not shown on the diagram.)

In the second choice, the given angles do not have a common side. (They are actually "vertical" angles.)

In the 3rd choice, the common side is RN, and vertex point R is found on line MO. These angles are a linear pair:

... - MRN and NRO

-y varies inversely with x. If y = 8 and k (the constant of variation) = 19, what is x?

Dimas [21]

Answer:

Part 1) $x=2.375$

Part 2) $y=3.3$

Part 3) $k=6.7$

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form $y*x=k$ or $y=k/x$

Part 1) y varies inversely with x. If y = 8 and k (the constant of variation) = 19, what is x?

we know that

$y*x=k$

substitute the given values and solve for x

$8*x=19$

$x=19/8$

$x=2.375$

Part 2) y varies inversely with x, and k (the constant of variation) = 23. What is the value of y when x = 7?

we know that

$y*x=k$

substitute the given values and solve for y

$y*7=23$

$y=23/7$

$y=3.3$

Part 3) y varies inversely with x. When y = 6.7, x = 1. What is the value of k, the constant of inverse variation?

we know that

$y*x=k$

substitute the given values and solve for k

$6.7*1=k$

$k=6.7$

Factor completely: What ways can I factor this out to make it less complicated

Mkey [24]

6x² - x -12. This is a quadratic equation. Find its roots (Zeros):

x' = [-b+√(b²-4.a.c)]/2a and x" = [-b-√(b²-4.a.c)]/2a

x' = 3/2 and x" = - 4/3

remember : ax²+bx + c = a(x-x')(x-x')

Then 6x² -x - 12 = 6(x-3/2)(x+4/3) (Reduce to the same denominator and simplify after reduction):
(2x-3)(3x+4)
