Perimeter of her rectangular back yard is: 200 ft

Write the equation of the line that passes through the points (8,−7) and (−9,7). Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal line.

Answers

Answer:

y + 7 = (-14/17)(x - 8)

Step-by-step explanation:

We want the equation of this line in the point-slope form y - k = m(x - h).

We are given two points (8, -7) and (-9, 7), and may arbitrarily choose one of them to serve as the point (h, k) in the point-slope form shown above.  Then the other point is represented by (x, y) in the point slope form shown above:

Let (h, k) be 8, -7) and let (x, y) be (-9, 7).  Then,  y - k = m(x - h) becomes:

7 - (-7) = m(-9 - 8), so that 14 = m(-17), and the slope is thus m = -14/17

The desired equation is then y + 7 = (-14/17)(x - 8) (which is in point-slope form).  

Another way to get this result would be to find m in the usual way:

          rise           14

m = ------------- = --------- = -14/17 (same as before).

           run           -17

After applying the linear combination method, Heather arrived at the equation 0 = 60. What conclusion can be drawn about the system of equations? The equation has no solution; therefore, the system of equations has no solution. The equation has a solution at (0, 60); therefore, the system of equations has a solution at (0, 60). The equation has infinite solutions; therefore, the system of equation as infinite solutions. The equation has a solution at (0, 0); therefore, the system of equations has a solution at (0, 0).

Answers

Answer:

The correct answer is:

The equation has no solution; therefore, the system of equations has no solution.

Step-by-step explanation:

When solving a system of equations, after we combine the equations, if we find that there is no solution, that means that there is no solution to the entire system of equations.

Let b be the number of blue beads and g the number of green beads that Giovanni can use for a belt.

He's supposed to use a total of between 70 and 74 beads, so

70 ≤ b + g ≤ 74

The ratio of green beads to blue beads is g/b, and this ratio has to be between 1.4 and 1.6, so

1.4 ≤ g/b ≤ 1.6

For completeness, Giovanni must use at least one of either bead color, so it sort of goes without saying that this system must also include the conditions

b ≥ 0

g ≥ 0

(These conditions "go without saying" because they are implied by the others. g/b is a positive number, so either both b and g are positive, or they're both negative. But they must both be positive, because otherwise b + g would be negative. I would argue for including them, though.)

Answers

Answer:

11.25 days

Explanation:

15 / 12 = 1.25

1.25 x 0.75 = 0.9275

0.9375 x 12 = 11.25

I suggest you do this
15 times .25 and it will give you how many people you will have. Then you do 15/12 which gives you 1.25 then you multiply how many people you have and 1.25

Answers

Answer:

Given : Michael and Imani go out to eat for lunch.

their food and beverages cost $25.30

8% meals tax,

After adding a tip, the total lunch cost was $32.24

To Find : how much is the bill

What percentage tip did they give?

Solution:

food and beverages cost $25.30

8% meals tax,

Tax = (8/100) 25.3 =  2.02 $

BILL = 25.30 + 2.02

= 27.32  $

BILL = 27.32  $

After adding a tip, the total lunch cost was $32.24.

=> Tip = 32.24. -  27.32  = 4.92$

% of Tip  = (4.92 /  27.32) * 100 =  18 %

Tip = 18 %

Step-by-step explanation:

Answer:

Part A:  $28.46

Part B:   8.5%

Step-by-step explanation:

Part A:

We know that in this equation that 25.30 is the 100% number and we need to find 8% of this.

We can then divide  8 by 25.30 which is 3.1625 but the problem asks us to "round to the nearest cent" so we then know that the 8% is $3.16 we have to then add the 8% to the total which would be:      25.30 + 3.16 which equals $28.46 which is your answer to Part A.

Part B:

After adding a tip that problem states that the total went up from $28.46 to $32.24 to find out how much they tipped we can minus these 2 totals to find the difference

32.24 - 28.46 = 3.78

We now know that they tipped $3.78 and we now need to convert this into a percentage.

Right now the whole 100% is $32.24, we then divided 32.24 by 3.78 which would be 8.5291 and so on but wo round this it would be 8.5%

The answer to Part B would be 8.5%

So with this, you need to add 70° and 70°.

You get 140°

Then to find the last angle, you will subtract the 140° by 180°.

180°-140° = 40°

Hope this helped! :)

First you add 70 and 70 together to get 140 then minus it by 180.
