Use the discriminant to determine the number of real solutions of the equation.<br> x^2 = -6x - 10
HACTEHA [7]

Answer:

No real solutions.

Step-by-step explanation:

x² + 6x + 10 = 0

a = 1

b = 6

c = 10

D = b² - 4ac = 6² - 4*1*10 = 36 - 40 = - 4

- 4 < 0,

so this equation has no real solutions.

Which expression is equivalent to 128x^5y^6 \ 2x^7y^5 ? Assume x &gt; 0 and y &gt; 0.
N76 [4]

Answer: Last option.

Step-by-step explanation:

Given the expression:

\sqrt{\frac{128x^5y^6}{2x^7y^5}

The Quotient of powers property states that:

\frac{a^m}{a^n}=a^{(m-n)}

And the Power of a powet property states that:

(a^m)^n=a^{mn}

Then, applying these properties, you get:

=\sqrt{\frac{(2^3)^26y}{x^2}

Now you must remember that:

\sqrt[a]{a^n}=a

Therefore, simpliying the expression, you get:

=\frac{2^3\sqrt{y}}{x}=\frac{8\sqrt{y}}{x}

Identify a transformation of the function f(x) = x^2 by observing the equation of the function g(x) = (x - 6)^2.
Thepotemich [5.8K]
The correct answer is the third option:

The base graph has shifted 6 units to the right.

It is a horizontal translation, because it involves the subtraction of “h” from inputs (x values) causing it to shift to the right,
