Answer:

The slope is 1

The equation is y = x+3

Step-by-step explanation:

To find the slope between 2 points

m = (y2-y1)/ (x2-x1)

= (9-5)/ (6-2)

= 4/4

The equation of the line is

y-y1 = m(x-x1)

y-5 = 1(x-2)

y-5= x-2

Add 5 to each side

y-5+5 = x-2+5

y = x+3

Could someone explain this to me?

Ilya [14]

This is a simple differentiation problem. Let's start by taking the derivative of both sides (with respect to x):
$5y^4\frac{dy}{dx}+6y^2x+6x^2y\frac{dy}{dx}+20x^3 = 0$

Simplify:
$\frac{dy}{dx} (5y^4+6x^2y) + 6y^2x+20x^3 = 0$

Solve for dy/dx:
$\frac{dy}{dx} = \frac{-6y^2x-20x^3}{5y^4+6x^2y}$

Now, plug in the given points:
$\frac{dy}{dx} = \frac{-6(2)^2(-1)-20(-1)^3}{5(2)^4+6(-1)^2(2)} = \frac{24+20}{80+12}$

Further simplification gives:
$\frac{dy}{dx}|_{(2,-1)} =\frac{44}{92} = \frac{11}{23}$

So, your answer is 11/23 or B.

Whats the middle number of 15 and 24

never [62]

Answer:

19.5

Step-by-step explanation:

15+24=39

39 divided by 2

=19.5

If there is an even number of numbers locate the two middle numbers so that there is an equal number of values to the left and to the right of these two numbers. Step 3: If there is an odd number of numbers, this middle number is the median. If there is an even number of numbers add the two middles and divide by 2.

Answer:

a ≤ 15

Equality Properties

Step-by-step explanation:

Step 1: Define

3(a - 4) ≤ 33

Step 2: Solve for a

Divide 3 on both sides: a - 4 ≤ 11
Add 4 on both sides: a ≤ 15

Here we see that any value a less than or equal to 15 would work as a solution to the inequality.
