Answer:

-10 = x

Step-by-step explanation:

1) combine all like terms

bring 4x and "x" to the right side to combine them

if we do this they will become negative

-2=3x+8+3x-4x-x

now bring "8" to the left side if we do this 8 will become negative

-8-2=3x+3x-4x-x

now we can combine like terms

-10=6x-5x

-10=x

Hope this helps!

4x – 2 + x = 3x + 8 + 3x

Combine like terms:

4x+x-2=3x+3x+8

5x-2=6x+8

Move 6x to the other side. Sign changes from +6x to -6x.

5x-6x-2=6x-6x+8

5x-6x-2=8

-x-2=8

Move -2 to the other side.

-x-2+2=8+2

-x=10

Multiply both sides by -1.

(-1)(-x)=(10)(-1)

x=-10

Answer: x=-10

Explain why the sum or product of rational numbers is rational; why the sum of a rational number and an irrational number is irr

Colt1911 [192]

Answer:

Rational numbers are fractional numbers, whose numerator and denominator are integers and the denominator is ever zero.

Step-by-step explanation:

The sum of rational numbers gives a rational number;

$\frac{1}{3}$ + $\frac{1}{3}$ = $\frac{2}{3}$ , because the evaluation of the denominator always results to a non-zero integer.

The product of $\frac{1}{3}$ x $\frac{1}{3}$ = $\frac{1}{9}$ , which multiply both numerator and denominator to give integer numbers.

The sum and product of rational and irrational numbers are always irrational numbers, for instance,

$\frac{1}{3}$ x 7 = 2.3 , which is a number which decimal points that can only be represented by the product irrational number and rational number , where 7 is an irrational number.

$\frac{1}{3}$ + 7 = 7 $\frac{1}{3}$ , which is a whole number and fractional number combined.

How tall is the flag pole (please give explanation too)

Tpy6a [65]

Answer:

22 3/4 ft

Step-by-step explanation:

The diagram seems to show a 6 1/2 ft person casting a 9 ft shadow at the same time a flagpole is casting a 31 1/2 ft shadow. You want the height of the flagpole.

<h3>Proportion</h3>

Shadow lengths are presumed proportional to the height of the object making them. This means ...

h/(31 1/2) = (6 1/2)/9 . . . . . all lengths in feet

Multiplying by 31 1/2, we get ...

h = (31 1/2)(6 1/2)/9 = (819/4)/9 = 91/4

h = 22 3/4 . . . . ft

The flagpole is 22 3/4 feet tall.

Answer:

$x^2 + 10x + y^2 -4y + -7 = 0$

Step-by-step explanation:

For any circle point with coordinate of center (a,b) and radius r

equation of circle is given by

$(x-a)^2 + (y-b)^2 = r^2$

_______________________________________

Given

coordinate of center = (-5,2)

radius = 6

thus, equation of circle can be written by substituting a and b with (-5 ,2) and r =6 as shown below

$(x-a)^2 + (y-b)^2 = r^2\\(x-(-5))^2 + (y-2)^2 = 6^2\\x^2 + 10x + 25 + y^2 -4y + 4 = 36\\=>x^2 + 10x + y^2 -4y + 29 = 36\\=>x^2 + 10x + y^2 -4y + 29 -36 = 36 -36\\=>x^2 + 10x + y^2 -4y + -7 = 0$
