Answer:

The last one.

Step-by-step explanation:

You can begin by dividing by - 2

-2*abs(x) =-6

-2*abs(x)/-2 = - 6/-2

abs(x) = 3

So x can be -3 or 3. Both are solutions

That's the last one.

The difference between two numbers is 5. three times the larger number is equal to four times the smaller number plus 6. what ar
UkoKoshka [18]
Let x and y represent the smaller and larger numbers, respectively.
  y - x = 5 . . . . . the difference is 5
  3y = 4x + 6 . . 3 times the larger is 4 times the smaller plus 6

Add x to the first equation to get an expression for y.
  y = x + 5
Use that in the second equation.
  3(x + 5) = 4x + 6
  3x + 15 = 4x + 6 . . . . . eliminate parentheses
  9 = x . . . . . . . . . . . . . . add -3x-6
  y = x+5 = 14

smaller number: 9
larger number: 14

Find a polar equation that has the same graph as the equation in x and y.<br> x^2 + y^2 = 5
Alex17521 [72]
X^2 + y^2 can be replaced by r^2 to obtain the polar equation equivalent to x^2 + y^2 = 5.  Thus, r^2 = 5, and r = sqrt(5).  That's all that's necessary.  No matter what the angle is, r will always be sqrt(5).

Solve the equation: <img src="https://tex.z-dn.net/?f=5%5Ex%5E%28%5Ex%5E-%5E1%5E%29%3D1" id="TexFormula1" title="5^x^(^x^-^1^)=1
Tomtit [17]

<u>The concept:</u>

We are given the equation:

5^{x(x-1)} = 1

Which can be simplified as:

5^{x^{2} - x} = 1^{1}

Since any number to the power '0' is 1

x² - x must be equal to 0 for the given equation to be true

<u></u>

<u>Solving for x:</u>

x² - x = 0

x(x-1) = 0

now, we can divide both sides by either x OR x-1

So we will see what we get for either choice:

x = 0/(x-1)                           x-1 = 0/x

x = 0                                  x = 1

Hence, the value of x is either 0 or 1
