Answer:

The equation of line in point-slope form is: [tex]y-7 = -7(x+5)[/tex]

Step-by-step explanation:

Given points are:

(x1,y1) = (-5,7)

(x2,y2) = (-4,0)

Point slope form of equation is given by:

[tex]y-y_1 = m(x-x_1)[/tex]

Here m is the slope

The slope is calculated using the formula:

[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]

Putting the values we get

[tex]m = \frac{0-7}{-4+5}\\m = \frac{-7}{1}\\m = -7[/tex]

Putting in the equation we get

[tex]y-y_1 = -7(x-x_1)[/tex]

Putting (-5,7) in the equation

[tex]y - 7 = -7\{x-(-5)\}\\y-7 = -7(x+5)[/tex]

Hence,

The equation of line in point-slope form is: [tex]y-7 = -7(x+5)[/tex]

Answer:

M=12

Step-by-step explanation:

The required length of MN in the given triangle LMN is 16 units.

A polygon with three vertices, angles and sides is called a triangle.

Given that, a triangle △ LMN, where, ∠ M ≅ ∠ L, LM = 7 and LN = 16

Since, ∠ M ≅ ∠ L

Therefore, MN ≅ LN

By the postulate :-

Sides opposite to congruent angles of a triangle are also congruent.

Therefore,

MN = LN

Since, LN = 16

Therefore, MN = 16 [By transitive property]

Hence, the required length of MN in the given triangle LMN is 16 units.

Answer:

yes because the equation will equal 2

Susan earns $11.50 per hour.

The correct answer is option (D).

"It is the ratio or comparison of two related quantities."

"When one quantity is proportional to other quantity, this means with increase in the values of first quantity there is equal increase/decrease in the values of second quantity."

For given situation,

Susan's weekly earnings were proportional to the number of hours she worked.

From given table, we can observe that with increase in the number of hours Susan worked, there in increase in the weekly earnings.

This means, Susan's weekly earnings are directly proportional to the number of hours she worked.

We need to find the amount of money she earn per hour, i.e., to find the ratio of her total earnings and total hours she worked.

Let S represents Susan's total earning and T represents the total number of hours she worked.

⇒ S = 57.50 + 80.50 + 103.50 + 126.50

⇒ S = 368

And T = 5+ 7 + 9 + 11

⇒ T = 32

Now we find the required ratio,

S/T = 368/T

⇒ S/T = 11.5 dollar per hour

Therefore, Susan earn $11.5 per hour.

Hence, option (D)$11.50 is the correct option.

68°

Step-by-step explanation:

Since, angle subtended on the circumference of the circle is half angle subtended on the center of the circle.

[tex] \therefore m\angle DBR = \frac{1}{2} \times m\angle DAR\\\\

\therefore 34\degree = \frac{1}{2} \times m\angle DAR\\\\

\therefore 34\degree \times 2= m\angle DAR\\\\

\therefore 68\degree = m\angle DAR\\\\

=========================================

Work Shown:

d = number of days of his vacation

1 day = 1*2 = 2 outfits

2 days = 2*2 = 4 outfits

3 days = 3*2 = 6 outfits

4 days = 4*2 = 8 outfits

5 days = 5*2 = 10 outfits

and so on.

In general we can say,

d days = d*2 = 2d outfits

d is simply a placeholder or a box where we'll place a number inside. For example, if he's on vacation for d = 7 days, then he'll bring 2*d = 2*7 = 14 outfits.

The expression 2*d is the same as 2d. We can leave out the multiplication sign since having a number next to a variable like this implies multiplication.

The expression for the total number of outfits is 2d

The total number of outfits Tyler plans to pack for his vacation can be expressed as 2 multiplied by the number of days of his vacation, which we'll denote as 'd'. Since Tyler plans to pack two outfits for each day, multiplying 'd' by 2 will give us the total number of outfits.

In this expression, 'd' represents the number of days of Tyler's vacation, and multiplying it by 2 accounts for the two outfits planned for each day. This expression allows us to calculate the total number of outfits based on the length of Tyler's vacation.

For example, if Tyler's vacation is 7 days long, the expression 2d would yield:

2 * 7 = 14

Therefore, Tyler would plan to pack 14 outfits for his 7-day vacation. The expression 2d allows flexibility to calculate the total number of outfits based on the specific number of vacation days.
