Answer:

Refer to the attachment for the labelling of the triangles.

In △ABC & △PQR,

∠A = ∠R (equal pair of angles)

∠B = ∠Q (equal pair of angles)

AC = PR (equal pair of sides)

•°• △ABC ≅ △RQP (Angle-Angle-Side congruence property → AAS property)

The domain of the function shown in the graph are all real numbers. Therefore, option C is the correct answer.

The domain and range are defined for a relation and they are the sets of all the x-coordinates and all the y-coordinates of ordered pairs respectively.

The coordinate points from the given graph are (-2, 0) and (10, 6).

Here, slope m=(6-0)/(10+2)

= 6/12

= 1/2

= 0.5

Substitute m=0.5 and (x, y)=(-2, 0) in y=mx+c, we get

0=0.5(-2)+c

0=-1+c

c=1

So, equation of a line is y=0.5x+1

Find the domain by finding where the equation is defined. The range is the set of values that correspond with the domain.

Domain: (−∞,∞),{x|x∈R}

Range: (−∞,∞),{y|y∈R}

Therefore, option C is the correct answer.

Answer:

a b c d

Step-by-step explanation:

The resulting equation will be x + y = 4 and 4y =20

GIven the system of equation given as:

x + y = 4

-3x + y = 8

If Megan multiplies the first equation by 3 then add the result to the second equation, the resulting equation will be:

3x  + 3y = 12

-3x + y = 8

Adding both equation

3y + y = 12 + 8

4y = 20

Hence the resulting equation will be x + y = 4 and 4y =20

Answer:

60

Step-by-step explanation:

All angles in a triangle have to add up to 180

60+ 60 + angle 3=180

120 + angle 3= 180

angle 3 = 60

Answer:

x = 2

Step-by-step explanation:

[tex]\frac{x+1}{x+3}[/tex] = [tex]\frac{3}{5}[/tex] ( cross- multiply )

5(x + 1) = 3(x + 3) ← distribute parenthesis on both sides

5x + 5 = 3x + 9 ( subtract 3x from both sides )

2x + 5 = 9 ( subtract 5 from both sides )

2x = 4 ( divide both sides by 2 )

x = 2

Answer: C

Step-by-step explanation:

Opposite angles of a parallelogram are congruent, so:

3x+15 = 2x+35

x+15=35

Answer:

A polyhedron is a 3-dimensional solid made by joining together polygons. The word 'polyhedron' comes from two Greek words, poly meaning many, and hedron referring to surface. The polyhedrons are defined by the number of faces it has.

You and four friends = 5 people

To see how much one ticket costs we have to divide the total amount spent by the number of people who bought tickets.

Total amount spent: $110

People who bought tickets:5

110÷5=22

Each ticket cost $22

Answer:

$110÷5

=$22

therefore each ticket costs $22

Answer:

x = 2√2

y = 2√6

Step-by-step explanation:

Consider the ratio of the two legs of the two smaller interior right triangles. (refer to attached diagrams for the triangles - I have outlined one in blue and the other in red)

These will be equal since the triangles are similar

shorter leg : longer leg

(blue triangle = red triangle)

⇒ x : 4 = 2 : x

⇒ x/4 = 2/x

⇒ x² = 8

⇒ x = √8

⇒ x = 2√2

Now we have x, we have the two legs of the right triangle with hypotenuse labelled y.

Using Pythagoras' Theorem a² + b² = c² (where a and b are the legs and c is the hypotenuse)

⇒ 4² + (2√2)² = y²

⇒ y² = 24

⇒ y = √24

⇒ y = 2√6

Answer:

$4.14

Step-by-step explanation:

To find the unit price, we divide $24.81 by 6.

24.81/6 = 4.135

The question says to round to the nearest cent so we round it to 4.14.

4.135 = 4.14

Answer:

64.4

Step-by-step explanation:

In one of the trig formulas, it states    sin <a/A = sin<b/B = sin<c/C

So we have in this case:

sin(70)/12 = sin x/14           Note: x is just a variable for the angle <ABC

14(sin70)/12 = sin x

sin^-1(14(sin70)/12) = x

x=64.4

Answer: 165 cm^3

Step-by-step explanation:

Formula:

V = (4/3)π r^3

Knowns:

r = 3.4

Work:

- (4/3)π 3.4^3 ≈ 164.64 cm^3

- Now, round .6 to a 1 because it is >4, this turns 164.64 cm^3 into 165 cm^3

Answer:

165 cm^3

Answer:

f(x) = x(x + 2)(x + 9)(x - 8)²

Step-by-step explanation:

Given x = h is a zero of f(x) then (x - h) is a factor

If h has multiplicity 2 then the factor is squared , that is (x - h)²

here the zeros are x = 8 of multiplicity 2 , x = - 2, x = - 9, x = 0

then (x - 8)² , (x - (- 2)) , (x - (- 9)) , x - 0 are the factors, that is

(x - 8)² , (x + 2) , (x + 9) and x

f(x) = x(x + 2)(x + 9)(x - 8)² ← in factored form

Answer:

[tex]\displaystyle [0, 8][/tex]

Explanation:

This is an automatic give-away. If you look clocer, you will see that both equations have identical b-values of 8, telling you that both equations have identical y-intercepts. So, by definition, x is zero, which means you are left with the b-value of eight, giving you the solution to the system.

Answer:

The set of numbers a = 3, b = 6, and c = 9 proves the hypothesis because 3 is a factor of 6 and 3 is a factor of 9. Property 1 states that therefore 3 is a factor of 9 + 3 =12, which we know is true because 3 × 4=12. You can prove that this property is true for all integers if you know what the term factor means.
