Which equations represent the line that’s passes through points (1,-5) and (3,-17)
Nutka1998 [239]

(1,-5)(3,-17)

slope = (-17 - (-5) / (3 - 1) = - 12/2 = - 6


y = mx + b

slope(m) = -6

use either of ur points...(1,-5)...x = 1 and y = -5

now we sub and find b, the y int

-5 = -6(1) + b

-5 = -6 + b

-5 + 6 = b

1 = b

so ur equation is : y = -6x + 1....or 6x + y = 1

Hope this helps!

Mrs. Julien’s and Mrs. Castillejo’s classes are selling cookie dough for a school fundraiser. Customers can buy packages of maca
Oksi-84 [34.3K]

Answer: the cost of one package of macadamia nut chip cookie dough is $1.5

the cost of one package of triple chocolate cookie dough is $2.5

Step-by-step explanation:

Let x represent the cost of one package of macadamia nut chip cookie dough.

Let y represent the cost of one package of triple chocolate cookie dough.

Mrs. Julien’s class sold 25 packages of macadamia nut chip cookie dough and 30 packages of triple chocolate cookie dough for a total of $112.50. This means that

25x + 30y = 112.5 - - - - - - - - - - - - -1

Mrs. Castillejo’s class sold 8 packages of macadamia nut chip cookie dough and 45 packages of triple chocolate cookie dough for a total of $124.50. This means that

8x + 45y = 124.5 - - - - - - - - - - -2

Multiplying equation 1 by 8 and equation 2 by 25, it becomes

200x + 240y = 900

200x + 1125 = 3112.5

Subtracting, it becomes

- 885y = - 2212.5

y = - 2212.5/- 885

y = 2.5

Substituting y = 2.5 into equation 1, it becomes

25x + 30 × 2.5 = 112.5

25x + 75 = 112.5

25x = 112.5 - 75 = 37.5

x = 37.5/25 = 1.5

The method used is the elimination method. It is more convenient to use.

A company will need 25,000 in 7 years for a new additon. To meet this goal, the company deposits money into an account today tha
Mrac [35]
You can use the simple interest formula 
P = irt

We need P, which is the primary (or principal) investment, and we know that:

rate = 3% (0.03)
time = 7
i = $25000

So, just plug in and solve:
I = 25000(0.03)(7)
I = 5250

The company needs to invest $5250 today, to make $25000 in 7 years.

Answer:

0.7

Step-by-step explanation:

<u>Take the scale factor as Z.</u>

9 x Z = 6.3

14 x Z = 9.8

7 x Z = 4.9

<u>Find Z</u>

6.3/9 = 0.7

9.8/14 = 0.7

4.9/7 = 0.7

Z = 0.7

I'm not sure how to set this up

So hmmm notice the picture below

recall the "inscribed angle" theorem, an angle inscribed is half the intercepted arc

now, the line BA goes through the center, and to each end, thus is a diameter, the point of tangency, where a tangent hits the diameter or radius of a circle, is always a right-angle
