Answer:

X=1, x=-1

Step-by-step explanation:

Solve the equation first by substaracting according to the variable.

It will be =

X^2 - 1

Factorize the equation And you'll get

(x+1)(x-1)

Then equate both with zero.

X+1 = 0

X = -1

X-1 = 0

X = 1

If we fill a wheelbarrow with dirt, it ways 60 pounds. When we only fill the wheelbarrow 1/4 full, it weighs 33 pounds. How much
irga5000 [103]

Answer:

24 pounds

Step-by-step explanation:

Let's call the weight of the empty wheelbarrow X, and the weight of dirt to fill the wheelbarrow Y.

So, we can formulate the following equations:

X + Y = 60

X + (1/4)*Y = 33

Subtracting the second equation from the first one, we have:

3/4 * Y = 27

Y = 27 * 4 / 3 = 36

Now, we can calculate X:

X + 36 = 60

X = 24 pounds

Semenov [28]

Answer:

The given statement is false.

Step-by-step explanation:

Reason

let D be a directed graph with 'n' no of vertices and 'E' edges.

where 'n'=1.  thus D =(n,E).

In degree: in directed graph the number of incoming edges on a vertex is known as indegree.

it is denoted as deg ⁺(n).

And now we know that in a directed graph

if deg ⁻(n)= deg ⁺(n) for each vertex n.
