The answer is -2. -2 is the slope.

The slope is -2/5.

I picked 2 points on the graph and found the slope using the slope formula.

y₂ - y₁ -4 - (-2) -4 + 2 -2
------------ = -------------- = ------------ = ------
x₂ - x₁ 5 - 0 5 5

You can also find slope by using rise/run:
1). Pick 2 points on a graph.
2). The goal is to connect those two points.
3). Count a certain amount of units up and across to get to your second point.
4). If your second point is negative, you have to count a certain amount of units down and across to reach your second point.

If my words don't make any sense, check out www.algebra-class.com. There is a full explanation of this.

I hope I could help you!

Graph the rational function y=x/x^2+2x+1. Both branches of the rational function pass through which quadrant?

Hitman42 [59]

Answer:

Quadrant 3

Step-by-step explanation:

Here we have to graph the function y = x/(x^2 + 2x + 1)

The denominator can be factored.

x^2 + 2x + 1 = (x + 1)(x + 1)

y = x/(x + 1)(x + 1)

Now we have to graph this function and see in which quadrant the function's both branches passes through.

Herewith I have attached the graph.

Here we can see both branches pass through Quadrant 3.

I hope this will helpful.

Thank you.

pls help me do if u don't know how to do pls don't answer or else u will be reported I need it under 25min thank u

Vesna [10]

Answer:

see explanation

Step-by-step explanation:

given that V is directly proportional to u and inversely proportional to f , then the equation relating them is

V = $\frac{ku}{f}$ ← k is the constant of proportion

(a)

to find k use the condition when u = 1 and f = 3 , V = $\frac{1}{6}$ , then

$\frac{1}{6}$ = $\frac{k}{3}$ ( cross- multiply )

6k = 3 ( divide both sides by 6 )

k = $\frac{3}{6}$ = $\frac{1}{2}$

V = $\frac{u}{2f}$ ← equation of proportion

(b)

when f = 4 and V = 1 $\frac{1}{4}$ = $\frac{5}{4}$ , then

$\frac{5}{4}$ = $\frac{u}{2(4)}$ = $\frac{u}{8}$ ( cross- multiply )

4u = 40 ( divide both sides by 4 )

u = 10

Which of the following polynomials corresponds to the subtraction of the multivariate polynomials 19x^3+44x^2y+17 and y^3-11xy^2

VARVARA [1.3K]

Name the two given polynomials as
f(x) = 19x³ + 44x²y + 17
g(x) = y³ - 11xy² + 2x²y - 13x³

Create the subtraction f(x) - g(x).
f(x)-g(x) = 19x³ + 44x²y + 17 - (y³ - 11xy² + 2x²y - 13x³)
= (19 + 13)x³ + (44 - 2)x²y + 11xy² - y³ + 17
= 32x³ - y³ + 42x²y + 11xy² + 17

Answer: D
Note that answer D has a typo. 11xy² is correct, but 11x²y is not.
