(-7,-2) is the point which is two-sevenths of the distance from a(-9, 2) to b(-2, -12).

since the unknown point m divides line joining a(-9,2) and b(-2,-12) in a given ratio of 2:5 as it is given one point is at distance of 2/7 of distance between point a and b so, the other point must be at a distance of 5/7 and hence the ratio in which it divides itself is 2:5

   a_______________m_________________________b

           2                        :                5

in the above figure it is shown clearly that m divides line joining point a and point b in the ratio of 2:5

let (x,y) be cordinate of point  m

[tex](x_1 , y_1)[/tex] be the point a

[tex](x_2 , y_2)[/tex] be point b

m:n =2:5

m=2 ,n=5

so applying section formula

   x= [tex]\frac{mx_2+nx_1}{m+n}[/tex]  

   => x = (2* -2 + 5 *-9) / (5+ 2)

   => x = - 49/7 = -7

   y= [tex]\frac{my_2+ny_1}{m+n}[/tex]  

 => y = (2* -12+5 *2)/(5+2)

 => y =  -2

  so the point m is (-7,-2) is the required answer of the question

Answer:

20.50 < 13 + .75n; 10 < n

Step-by-step explanation:

First let us set up 2 equations to represent how much these payment methods are giving per hour:

f(n) = 20.50

g(n) = 13 + .75n

We want to find where f(n) < g(n):

20.50 < 13 + .75n → subtract 13

7.50 < .75n  → divide by .75

10 < n

Thus, we would need to produce more than 10 units per hour to get the second option to be more profitable

By solving for the number of employees, there were 70 employees at the party.

An equation is a mathematical statement that shows that two expressions are equal. An equation typically consists of two sides, with an equals sign (=) in between.

A linear equation is an equation in which the highest power of the variable is 1. In other words, a linear equation is an equation that can be written in the form:

ax + b = 0

where a and b are constants and x is the variable.

To find out how many employees attended the party, you can set up the following equation:

Number of employees * $30 per employee = $1000 for space + $850 for food + $250 for decorations

You can then solve for the number of employees by dividing both sides of the equation by $30 per employee:

Number of employees = ($1000 for space + $850 for food + $250 for decorations) / $30 per employee

= $2100 / $30

Answer:

Step-by-step explanation:

You want the number of months and the total amount paid when you pay off a credit card debt of $1367.90 with 9.5% APR at the rate of $400 each month.

The amount of the payment that goes to interest each month is the monthly rate (9.5%/12) multiplied by the remaining balance. The first month's interest is ...

  $1367.90 × 0.095/12 = $10.8292 ≈ $10.83 . . . . rounded to cents

Then the balance is reduced by ...

  $400 -10.83 = $389.17

so it becomes ...

  $1367.90 -389.17 = $978.73 . . . . . balance after first payment

These calculations are repeated for subsequent payments. It is convenient to let a spreadsheet do them. (It can round the interest for you.) The results are shown in the attachment.

The negative balance for month 4 reflects the overpayment that a payment of $400 would be. The actual month 4 payment is the previous balance ($191.12) together with the interest due on that ($1.51), so is $192.63.

The total repaid is the sum of interest charges ($24.73) and the initial balance ($1367.90). That is, you paid off the initial balance and the interest due.

You repaid a total of $1392.63 in 4 months.

__

Additional comment

The steps for computing the total repaid are ...

Note, there are formulas for the payoff time and the total repaid. However, they do not take into account rounding of intermediate values, and they presume the last payment is made partway through the month. In short, it only gives an approximation of the amount repaid.

By listing actual amounts, rounded to cents, the actual amount repaid can be figured with no error. A spreadsheet is very helpful for that.

A line with a slope of 2 and a point at (4,3) satisfies the equation y = 2x - 5.

Two expressions joined by an equal sign form a mathematical statement known as an equation. An equation is, for instance, 3x - 5 = 16. We can solve this equation and determine that the value of the variable x is 7.

In general, a straight line has the equation y = mx + c, where m denotes the gradient and y = c denotes the point at which the line intersects the y-axis. do s s., s. s s.. s... s.. A straight line with a gradient of m and an intercept of c on the y-axis has the equation y = mx + c.

Here,

given: slope of 2/3

using formula

=>  y = mx + c.

=> (y-y') = m(x-x') + c

=> (y-4) = 2/3(x+3) + c

=> y = 2x - 5.

Let x be the number of miles the driver still has to travel.

The driver traveled 120 + 120/4 + 120/42/3 = 120 + 30 + 40 = 190 miles.

So the remaining distance is x + 190 = 55 + 1 2/3 * x

Multiplying both sides by 3/2 gives 3/2x + 3/2190 = 3/255 + 3/2*x + x

This simplifies to x = 190.

Therefore, the driver still has to travel 190 miles.

The rate of change of the height of the top of the ladder above the ground at the instant when the base of the ladder is 30 ft. from the base of the building is -3 ft./min.

The rate of change of the height of the top of the ladder above the ground at the instant when the base of the ladder is 30 ft. from the base of the building is -3 ft./min. This rate takes into account the fact that the ladder is slipping at a rate of 3 ft./min. As the base of the ladder is slipping away from the building, the top of the ladder is moving down, hence the negative rate of change. This rate of change will remain the same until the base of the ladder has slipped the full 50 ft. from the base of the building. At this point, the rate of the change of the height of the top of the ladder will be 0, since the ladder will no longer be slipping.

The rate of change can be calculated as follows:

Rate of change = Change in height / Change in time

Change in height = Initial height - Final height

Initial height = 50 ft.

Final height = 50 ft. - 30 ft. = 20 ft.

Change in time = 30 ft. / 3 ft./min. = 10 min.

Rate of change = (50 ft. - 20 ft.) / 10 min. = -3 ft./min.
