What is the slope??????

Mathematics
1 answer:
nikitadnepr [17]3 years ago
7 0

Answer: The slope is 1/4.

Step-by-step explanation:

To find the slope, find two points on the line and find the difference in their y coordinates and divide it by the difference in their x coordinates .

(0,20)  and   (40,30)  

Difference in y: 30 - 20 = 10  

Difference in x:  40 - 0 = 40  

Slope:  10/ 40 = 1/4

Which is the equation of an ellipse with directrices at x = ±4 and foci at (2, 0) and (−2, 0)?
NemiM [27]

Answer:

x squared over 4 plus y squared over 8 equals 1

Step-by-step explanation:

The general equation of ellipse is given as;

(x²/a²) + (y²/b²) = 1

The coordinates of a foci are: (±c, 0) where;

c² = b² - a²

However, we know that equation of directrix is; x = ±a/e

Now, Directrix is given ±4

Thus, a/e = 4

a = 4e

We also know that c = ae from ellipse foci coordinates.

Thus, ae = 2

since ae = 2, then (4e)e = 2

4e² = 2

e² = 2/4

e = 1/2

Thus;

a = 4 × 1/2

a = 2

Since c² = b² - a²;

2² = b² - 2²

4 = b² - 4

b² = 8

From (x²/a²) + (y²/b²) = 1, we can put our values to get;

x²/4 + y²/8 = 1

What is 4b + 6 ≤ 18. I don't know how to solve it and don't know the answer.
wolverine [178]

Answer:

b≤3

Step-by-step explanation:

For this problem, you want to solve it similarly to linear equations.

We start with 4b+6≤18.

Subtracting 6 from both sides gives 4b≤12.

From there, in order to isolate the b, we must divide both sides by 4, leaving b≤3.

**This content involves solving linear inequalities, which you may wish to revise. I'm always happy to help!
