7 0

Answer:

(0,0) or Infinitely many solutions.

Step-by-step explanation:

-−4x−4y=0

−4x−4y+4y=0+4y(Add 4y to both sides)

−4x=4y

−4x/-4= 4y/-4

(Divide both sides by -4)

x=−y

4x+4y=0

4(−y)+4y=0

0=0

Separate the number 219 into three parts. The second number is two less than 5 times the first number, and the third number is 4
Sav [38]
Let us assume the first number = x
Then the second number = 5x -2
The third number = x + 4
The total number that needs to be divided into three parts is 219
Then we can write the equation as
x + 5x - 2 + x + 4 = 219
7x + 2 = 219
7x = 219 - 2
7x = 217
x = 217/7
  = 31
Then
First number = 31
Second number = 5x - 2
                           = (5 * 31) - 2
                           = 155 -2
                          = 153
Third number = x + 4
                       = 31 + 4
                       = 35
So the three numbers are 31, 153 and 35.

GEOMETRY:
iragen [17]

Answer:

See explanation

Step-by-step explanation:

∠POR is congruent to ∠VOE because they are vertical angles

∠PRV is congruent to ∠RVE because alternate interior angles are congruent when the lines are parallel.

VO is congruent to OR which is given

Therefore, ΔPRO is congruent to ΔEVO by the angle-side-angle theorem

So, PR is congruent to VE because corresponding parts of congruent triangles are congruent

A student writes "the quotient of 5 and x" to describe the algebraic expression -
pashok25 [27]

For this case we have to:

\frac {a} {b} = c

Where:

a: It's the Dividend

b: It is the Divider

c: Is the Quotient

Thus, the expression "the quotient of 5 and x" can be represented as:

\frac {5} {x} = y

Where "y" is the quotient of 5 and x.

ANswer:

\frac {5} {x} = y
