Radical 2x+5 equals x

1. Square both side.

2x+5 equals x square

Move everything to one side.
X square-2x-5=0

Since this time, we can't factor very well. We need to use the quadratic formula.

-b+- square root b square- 4ac divided by 2a

This gives: -(-2)* square root( 4-4(1)(5))/ 2

Notice that we get 2 plus and minus square root of -16.

Which is an imagery/ complex solution.

The value of x could be 2+i4/2 or 2-i4/2

Answer:

  x = 18

Step-by-step explanation:

Add the opposite of the constant (-5), and multiply by the inverse of the coefficient of x (2/3).

  \dfrac{2}{3}x -5=7\\\\\dfrac{2}{3}x=12 \qquad\text{add 5}\\\\x=\dfrac{3}{2}\cdot 12 \qquad\text{multiply by $\dfrac{3}{2}$}\\\\ \boxed{x=18}

LenaWriter [7]

Answer:

√74

Step-by-step explanation:

We know the pythagorian triplet that,

A^2 + B^2 = Hypotenuse^2

Or, 5^2 + 7^2 =Hypotenuse ^2

Or, 25+49= Hypotenuse^2

Or, 74 = Hypotenuse^2

Hypotenuse= √74

How many solutions does the system have? y=−2x+4
Anna11 [10]

Answer:

There is only one solution and the solution is (0,4).

Step-by-step explanation:

The given system has equations;

y=-2x+4

and

y=x^2-2x+4

We equate the two equations to determine their point of intersection;

x^2-2x+4=-2x+4

\Rightarrow x^2-2x+2x+4-4=0

\Rightarrow x^2=0

\Rightarrow x=0

We put x=0 into the first equation to get;

y=-2(0)+4=4

There is only one solution and the solution is (0,4).
