If a linear function contains the pairs (5,7) and (9,11), which pairs should have the reciprocal function to this one?

Please choose an answer.

a.
(7.5) and (11.9)


b.
(5.7) and (11.9)


c.
(5.7) and (9.11)


d.
(7.5) and (9.11)

Answer:

[-2.5, -2], [-2, -1.5], [1.5, 2] and [2, 2.5) were the  intervals show f(x) decreasing

A relation is a function if it has only One y-value for each x-value.

To find the intervals where a function is decreasing, you need to look for the parts of the function where the slope is negative.

In other words, you need to find the intervals where the function is going downhill.

By the given function or graph the intervals where f(x) is decreasing are

[-2.5, -2], [-2, -1.5], [1.5, 2] and [2, 2.5)

Hence, [-2.5, -2], [-2, -1.5], [1.5, 2] and [2, 2.5) were the  intervals show f(x) decreasing

Answer:

y=-4 and y=-8

Step-by-step explanation:

When you have an absolute value around something, you can remove it, expect it's like a square root, it's going to be a [tex]\pm[/tex]. Because 6+y could've been -2 and the absolute value just made it positive 2

So set 6+y equal to -2 and 2 to find the two solutions:

6+y = 2

y = -4

6+y = -2

y = -8

Hey there!

YOUR EQUATION: |6 + y| = 2

CONVERT THAT TO:

y + 6 = 2 OR y + 6 = -2

FIRST let’s solve for: y + 6 = 2

y + 6 = 2

SUBTRACT 6 to BOTH SIDES

y = 6 - 6 = 2 - 6

SIMPLIFY THAT!

y = 2 - 6

y = -4

Possible solution #1: y = -4

LASTLY let’s solve for: y + 6 = -2

y + 6 = -2
SUBTRACT 6 to BOTH SIDES

y + 6 - 6 = -2 - 6

SIMPLIFY THAT AS WELL!

y = -2 - 6

y = -8

Possible solution #2. y = -8

Therefore, your answer should be:

y = -4 or y = -8

Good luck on your assignment & enjoy your day!

Answer:

(B). 86°

Step-by-step explanation:

Answer:

Step-by-step explanation:

The angle sum theorem helps you compute the angle inside the triangle. The inscribed angle theorem helps you compute the arc measures outside the triangle.

The Angle Sum theorem tells you the sum of angles in a triangle is 180°. That lets you write the equation ...

  X +Y +Z = 180°

  X +69° +41° = 180°

The Inscribed Angle theorem tells you an inscribed angle has half the measure of the central angle subtending the same arc. The arc and the central angle have the same measure: twice that of the inscribed angle.

  arc ZY = 2×∠X

  arc XY = 2×∠Z

Using the equations we wrote describing the relationships of the unknowns to the known information, we find ...

  X = 180° -110° = 70°

  arc ZY = 2×70° = 140°

  arc XY = 2×41° = 82°

Answer:Angle x=70°

Step-by-step explanation:interior angles add up to 180° so we add 41° and 69°. After addition,you minus from 180° and you get 70°

Step-by-step explanation:

I just saw that 44 + 44 equals 88 and compared those two sides, I knew it couldn't be 88, so that's out.  Then, I saw that the side, 21 + 21, was shorter than the unknown side and that ruled out 42 and 30.  60 is the only one that is left and makes sense.

The given linear equation has one solution: (-0.6, 1.6). The correct option is the second option  one solution: (-0.6, 1.6)

From the question, we are to determine the number of solutions the given linear equation has

The given system of equations is

y = 2/3x+ 2    ---------- (1)

6x - 4y = -10   ---------- (2)

Substitute equation (1) into equation (2)

6x - 4y = -10

6x - 4(2/3x +2) = -10  

6x - 8/3x -8 = -10

6x - 8/3x  = -10 + 8

10x/3 = -2

10x = -2 × 3

10x = -6

x = -6/10

x = -0.6

Substitute the value of x into equation (1)

y = 2/3(-0.6)+ 2

y = -0.4 + 2

y = 1.6

The solution to the given system of equation is x = -0.6, y = 1.6. That is, (-0.6, 1.6)

Hence, the given linear equation has one solution: (-0.6, 1.6). The correct option is the second option  one solution: (-0.6, 1.6)

The graph of this function opens up and all the y-values range from -3 to infinity, so therefore the range is all x≥-3

The range of the function f(x) = |x| – 3 is {f(x) ∈ ℝ | f(x) ≥ –3}. The correct option is A.

The range of a function in mathematics can refer to one of two closely related ideas: The function's codomain a representation of the action A binary relation f between two sets X and Y is a function if there is exactly one y in Y such that f connects x to y for every x in X.

A function is defined as the expression that set up the relationship between the dependent variable and independent variable.

Answer:

Cos (30°) = √3/2

Step-by-step explanation:

that is the solution above

The value of the trigonometric equation cos ( 30 )° = √3/2

Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles

The six trigonometric functions are sin , cos , tan , cosec , sec and cot

Let the angle be θ , such that

sin θ = opposite / hypotenuse

cos θ = adjacent / hypotenuse

tan θ = opposite / adjacent

tan θ = sin θ / cos θ

cosec θ = 1/sin θ

sec θ = 1/cos θ

cot θ = 1/tan θ

Given data ,

Let the triangle be represented as ΔABC

Now , the measure of ∠BAC = 30°

The adjacent side of the triangle AC = √3 units

The hypotenuse of the triangle AB = 2 units

So , from the trigonometric relations  

cos θ = adjacent / hypotenuse

On simplifying , we get

cos ( 30 )° = √3/2

Therefore , the measure of cos ( 30 )° = √3/2

Hence , the trigonometric relation is cos ( 30 )° = √3/2

Answer:

Step-by-step explanation:

Pythagorean Theorem : a² + b² = c² ⇔ b² = c² - a²

Here, we have a = 4 and c = 6 so :

    b² = 6² - 4²

⇔ b² = 36 - 16

⇔b² = 20

⇔ b = √20  (and not b= -√20 because b ≥ 0)

Answer:

b = [tex]\sqrt{20}[/tex]

Step-by-step explanation:

Using the Pythagorean Theorem:

6² = 4² + b²

⇒ b² = 6² - 4²

⇒ b = [tex]\sqrt{6^2 - 4^2}[/tex]

⇒ b = [tex]\sqrt{36 - 16}[/tex]

⇒ b = [tex]\sqrt{20}[/tex]

Option B is right perpendicular bisectors of the sides of the triangle

If we draw a circle through all the vertices of a triangle then the circle obtained is the circumcircle of the given triangle. We have in a triangle there are some properties inherent.

One is the perpendicular bisectors of all sides are concurrent. These three concur at a point called the circumcentre of the triangle.

When we draw a perpendicular bisector for a side AB, we get that all points on the perpendicular bisector are equidistant from A and B.

When we take the point of intersection of the perpendicular bisector of AB and BC, we have the intersecting point S(say) is equidistant from A and B and also from B and C

In short, this is equidistant from all 3 vertices and hence is the centre of the circumcircle of triangle ABC

Therefore Option B is right perpendicular bisectors of the sides of the triangle.
