Point A is located at (−2, −6), and D is located at (−6, 8). Find the coordinates of the point that lies halfway between A and D

Afina-wow [57]

Answer:

(-4,1)

Step-by-step explanation:

Point A is located at (−2, −6), and D is located at (−6, 8).

We need to find the midpoint of A and D

Mid point formula is $(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})$

Point A is (-2,-6) that is (x1,y1)

Point D is (-6,8) that is (x2, y2)

plug in the values in the formula

$(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})$

$(\frac{-2-6}{2}, \frac{-6+8}{2})$

$(\frac{-8}{2}, \frac{2}{2})$

Mid point is (-4, 1)

Tickets to a local circus cost $5 for students and $8 for adults. A group of 9 people spent a total of $60. How many adults were

S_A_V [24]

Answer:

Step-by-step explanation:

You need to set up and solve a system of linear equations here.

Let s and a represent the number of students and adults respectively.

Then s + a = 9, and s = 9 - a.

Total ticket cost for the adults was ($8/adult)(a)

and for the students ($5/student)(s).

Total cost of the tickets was then ($8/adult)(a) + ($5/student)(s) = $60.

Then our system of linear equations is:

8a + 5s = 60

a + s = 9, or s = 9 - a. Substituting 9 - a for s, we get:

8a + 5(9 - a) = 60.

Then 8a + 45 - 5a = 60, or 3a = 15.

Solving for a, we get a = 5.

Solving for s using s = 9 - a, we get s = 9 - 5, or s = 4.

There were 5 adults in the group (and 4 students).

If someone can answer this, you are BEYOND SMARTT!!! But tell me how to do it too!!!!

andrezito [222]

Look at all the choices

we know that at t = 0, the height of the rock is 16

choices H and I do not have a value of 16 at t = 0.

H: h(0) = -5.2(0)² + 24(0) - 12 = -12
I: h(0) = -4.2(0)² + 26(0) - 20 = -20

so we are left with F and G

if we take choice F and plug in t = 1
h(1) = -4.7(1)² - 25(1) + 16 = -13.7
if we take choice G and plug in t = 1
h(1) = -4.7(1)² + 25(1) + 16 = 36.3

only choice G works for us since it has 36.3 at t = 1

you could have also put these points in a graphing calculator and then use the quadratic regression feature to get an equation that will model this data

On a coordinate plane, the coordinates of vertices R and T for a polygon are R(−6, 2) and T(1, 2). What is the length of Side RT

wolverine [178]

The distance between any two points can be found using the Pythagorean Theroem...

d^2=(x2-x1)^2+(y2-y1)^2 in this case

d^2=(2-2)^2+(1--6)^2

d^2=0+49

Since d>0

d=7 units

Write a sentence to compare the populations for each planet using the words 10 times as many.

irina [24]

Answer:

10 times

Step-by-step explanation:

Note : It is given that,

Planet Ruba has a population of 1 million aliens and Planet Zamba has 1 hundred thousand aliens.

We know that,

1 million = 1,000,000

1 hundred thousand = 100,000

If we divide 1,000,000 by 100,000, we can compare the populations of two planets. So, we get :

$\dfrac{1000000 }{100000}=10$

It means that the population of Ruba planet is 10 times that of the Zamba planet.
