Answer: -5

Explanation:
To solve this, plug in each of the answers as m (1, -5, -2, 5).

5(1) + 3 = 3(1) - 7
Answer: 8 = -4

5(-5) + 3 = 3(-5) - 7
Answer: -22 = -22

5(-2) + 3 = 3(-2) - 7
Answer: -7 = -13

5(5) + 3 = 3(5) - 7
Answer: 28 = 8

And as you can see, m = -5 gives us the answer -22 = -22, which is correct.

Hope this helped! :3

an ellipse has a center at the origin , a vertex along the major axis at (13,0), and a focus at (12,0). What is the equation of
-BARSIC- [3]

Answer:

The answer to your question is below

Step-by-step explanation:

Data

Center = (0, 0)

Vertex = (13, 0)

Focus = (12, 0)

Process

From the data we know that it is a horizontal ellipse.

1.- Calculate "a", the distance from the center to the vertex.

                  a = 13

2.- Calculate "c", the distance from the center to the focus

                  c = 12

3.- Calculate b

Use the Pythagorean theorem to find it

                  a² = b² + c²

-Solve for b

                  b² = a² - c²

-Substitution

                  b² = 13² - 12²

-Simplification

                  b² = 169 - 144

                  b² = 25

                  b = 5

4.- Find the equation of the ellipse

                       \frac{x^{2} }{13^{2}} + \frac{y^{2}}{5^{2}} = 1    or \frac{x^{2} }{169} + \frac{y^{2}}{25} = 1

Hong made 2 identical necklaces, each having beads and a pendant. The total cost of the beads and pendants for both necklaces wa
egoroff_w [7]
B+ p= 10.40
b=2x 2.50
Now using substitution method replace b in first equation with value of second equation basically combing the two equations into one do you end up with one variable to solve .
2 x 2.50 +p =10.40
5 + p=10.40
P=$5.40
b =$5.00
The answer is EACH pendant cost $2.70
(You have to divide 5.40 by two )

6x-21>3 and 14x+11>-17
Delicious77 [7]
6x-21>3
Add 21 to both sides
6x>24
Divide 6 on both sides
X>4

14x+11>-17
Subtract 11 from both sides
14x>-28
Divide 14 on both sides
X<-2
