Answer:

[tex]a_{n}[/tex] = - 4n + 6

Step-by-step explanation:

There is a common difference between consecutive terms of the sequence

- 2 - 2 = - 6 - (- 2) = - 10 - (- 6) = - 14 - (- 10) = - 4

This indicates the sequence is arithmetic with explicit formula

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

here a₁ = 2 and d = - 4 , then

[tex]a_{n}[/tex] = 2 - 4(n - 1) = 2 - 4n + 4 = - 4n + 6

The formula for slope is:  m  =  (y2 - y1) / (x2 - x1)   --->   m  =  (b - b) / (-a - a)  =  0/(-2a)  =  0

Answer:

a = 43/8

Step-by-step explanation:

8a-48+5+8a-43=0

16a-86=0

a=86/16

a=43/8

∠ABD and ∠EBC are complementary by the definition of complementary angles.

Given that in a figure, BD ⊥ BC ; ∠ABD ≅ ∠DBE.

We need to prove ∠ABD and ∠EBC are complementary.

BD ⊥ BC = given

∠DBC = 90° by the definition of perpendiculars.

∠ABD ≅ ∠DBE = given

∴ ∠ABD = ∠DBE by the definition of congruence.

Using the angles addition postulate,

∠EBC + ∠DBE = 90°

Now, replace ∠DBE by ∠ABD, we get,

∠EBC + ∠ABD = 90°

Hence ∠ABD and ∠EBC are complementary by the definition of complementary angles.

Answer:

h = 2[tex]\sqrt{3}[/tex]

b = 3[tex]\sqrt{2}[/tex]

Step-by-step explanation:

to find 'h' we can use the ratio of sides in a 30-60-90° triangle which, respectively, is 1 : [tex]\sqrt{3}[/tex] : 2

so we can set up this proportion:

h/2 = 1/[tex]\sqrt{3}[/tex]

cross-multiply:

h = 2[tex]\sqrt{3}[/tex]

to find 'b' we can use the ratio of sides in a 45-45-90° triangle which, respectively, is 1 : 1 : [tex]\sqrt{2}[/tex]

we can set up this proportion:

3/b = 1/[tex]\sqrt{2}[/tex]

cross-multiply:

b = 3[tex]\sqrt{2}[/tex]

sinθ is equal to the division of the opposite side of the reference angle (θ) by the hypotenuse.

the cosine of an angle in a right triangle equals the adjacent side divided by the hypotenuse

tan30 = h/2

[tex]tan30 = \frac{1}{ \sqrt{3} } [/tex]

1/sqrt3 = h/2

[tex]h = \frac{2}{ \sqrt{3} } [/tex]

sin45 = 3/b

[tex]sin45 = \frac{1}{ \sqrt{2} } [/tex]

1/sqrt2 = 3/b

Answer:

They are not equivalent

Step-by-step explanation:

[tex]{ \tt{ - 9h - 4.5 \equiv - 0.75(12h - 4.5)}} \\ \\ { \tt{ - 9h - 4.5≠( - 9h + 3.375)}}[/tex]

Answer:

No, they are not equivalent.

Step-by-step explanation:

So in order to solve this question, you need to set the equations equal to each other. -9h-4.5=-0.75(12h-4.5)

Let's work on the left side first, only because it's going to take more work and because we need to solve it in order to continue the process. So you first are going to want to use the distributive property. Multiply 12h and -4.5 by -0.75. 12h*-0.75=-9h. -4.5*-0.75=3.375. so now your equation looks like -9h-4.5=-9h+3.375

So just looking at it, it seems as if these equations are not equivalent, just parallel.

Answer:

x = -2  ||   y = -3

Step-by-step explanation:

5x - 2y = -4

x + 2y = -8

--------------------------------------------

5x - 2y = -4

5x = -4 + 2y

x = (-4 + 2y)/5

x + 2y = -8

x = -8 - 2y

Solving simultaneously:

-8 - 2y  =   (-4 + 2y)/5

5(-8 - 2y) = -4 + 2y

-40 - 10y = -4 + 2y

-40 + 4 = 2y + 10y

-36 = 12y

y = -3

if y is -3 then x is:

x = -8 - 2y

x = -8 - 2(-3)

x = -2

2x^2 - x = 10

=> 2x^2 - x - 10 = 0

=> (2x - 5)(x + 2) = 0

Answer:

[tex]x1 = \frac{5}{2} \: \: and \: x2 = - 2[/tex]

Step-by-step explanation:

So, our equation is:

2x² - x - 10 = 0

The numbers before x are a, b, and c

We must first find the discriminant which is equal to b² - 4*a*c

D = b² - 4 * a * c

Be careful here, b is -1 because we have minus before x and c is -10

D = (-1)² - 4*2*-10

D = 1 + 80

D = 81

Now we need to find the roots of the equation, since D is greater than 0, the roots are equal to (-b ± sqrt(D)) / 2*a

[tex]x1 = \frac{ -( - 1) + \sqrt{81} }{2 \times 2} = \frac{1 + 9}{4} = \frac{10}{4} = \frac{5}{2} [/tex]

and for x2 we will put minus:

[tex]x2 = \frac{ - ( - 1) - \sqrt{81} }{2 \times 2} = \frac{1 - 9}{4} = \frac{ - 8}{4} = -2 [/tex]

Answer:

B

Step-by-step explanation:

Step-by-step explanation:

Let the two consecutive natural numbers be x and x+1

Now, according to the problem

x+(x+1)=23

⇒ 2x+1=23

⇒ 2x=23−1

⇒ 2x=22

⇒ x=22÷2=11

The one number is 11

The next number is x+1=11+1=12

Hence the numbers are 11 and 12.
