Answer:

$a_{23}$ = - 177

Step-by-step explanation:

The n th term formula for an arithmetic sequence is

$a_{n}$ = a + (n - 1)d

where a is the first term and d the common difference

d = - 9 - (- 1) = - 9 + 1 = - 8 and a = - 1, hence

$a_{23}$ = - 1 + (- 8 × 22) = - 1 - 176 = - 177

Which mathematical equation represents the solution for k in the equation h + 3 = jk + 6k ?

Tomtit [17]

Answer:

The answer is<u> D.</u> h+3/j+6.

Step-by-step explanation:

Given:

The equation h + 3 = jk + 6k.

Now, to get the mathematical expression.

$h + 3 = jk + 6k$

So, taking $k$ common on R.H.S we get:

$h + 3 = k(j + 6)$

Then, dividing both sides by $j+6$ we get:

$\frac{h+3}{j+6} =k$

Thus,

$k=\frac{h+3}{j+6}$

Therefore, the answer is D. h+3/j+6.

How many triangles can be formed with segments measuring 34 cm, 13 cm, and 38 cm? Select from the drop-down menu to correctly co

Lilit [14]

The triangle inequality theorem is not followed, no triangle can be formed.

Triangles

In Geometry, a triangle is a three-sided polygon that consists of three edges and three vertices.

The triangle inequality theorem describes the relationship between the three sides of a triangle.

According to the triangle inequality theorem, the sum of any two sides must be greater or equal than the length of the third side.

Here, the sides are 34 cm, 13 cm, and 38 cm.

34cm + 13 cm = 47 cm > 38cm (theorem followed)

34 cm + 38 cm = 72 cm > 13 cm (theorem followed)

13 cm + 38 cm = 51 cm < 34 cm (theorem not followed)

Since the triangle inequality theorem is not followed,

Hence, no triangle can be formed.

What is the slope of the line passing through the points (−3, −5) and (−1, −6)?

Virty [35]

Answer:

The slope of the line passing through the points (−3, −5) and (−1, −6) is $-\frac{ 1 }{ 2 }$ (-0.5)

Step-by-step explanation:

Equation of a straight line:

y = mx + b where m is the slope and b is the y-intercept

(x1, x2) and (y1, y2) : (−3, −5) and (−1, −6)

Calculating Slope (m).

m = $\frac{y_{2} - y_{1}}{x_{2} - x_{1}}$

m = $\frac{ (-6) - (-5) }{ (-1) - (-3) }$

m = $\frac{ -6 + 5 }{ -1 + 3 }$

m = $-\frac{ 1 }{ 2 }$

we can take this a step further by finding the equation:

Now putting value of m in equation (i)

y = -0.5x + b

Calculating Y-intercept (b).

Lets choose the first point, (-3,-5) for calculating y-intercept:

y = mx + b

-5 = -0.5(-3) + b

-5 = 1.5 + b

-6.5 = b

b = -6.5

Now putting value of b in equation

y = -0.5x + -6.5
