Which is equivalent to x^3 y^-7

PilotLPTM [1.2K]

For this case we must find an expression equivalent to:

$x ^ 3 * y ^ {- 7}$

By definition of power properties we have to meet:

$a ^ {-1} = \frac {1} {a ^ 1} = \frac {1} {a}$

Then, we can rewrite the expression as:

$x ^ 3 * \frac {1} {y ^ 7} =\\\frac {x ^ 3} {y ^ 7}$

Answer:

$\frac {x ^ 3} {y ^ 7}$

15 points+ brainliest!! please help :(!

son4ous [18]

Answer:

It's asking for a reflection. The point D is 5 points lower than the line, so the plot dot should be 5 points higher than the line, right above the other D point. Think of the line as a mirror.

The red dot in the attached image is the answer.

Find c to complete the perfect trinomial<br><br> x2 + 4x + c

sladkih [1.3K]

Answer:

Step-by-step explanation:

I assume that is supposed to be x squared. A perfect trinomial is the product of a perfect square, (x times a number) squared. With these trinomials, you can look at them as: ax squared times bx + c. When a is 1, the fastest way to get c to make a perfect square is to divide b by 2. In this case, it's 4/2 = 2. The last step is to square that number. 2 squared = 4.

Find the inverse function of f(x)= <img src="https://tex.z-dn.net/?f=%20%5Csqrt%7Bx%2B4%7D%20%2B7" id="TexFormula1" title=" \sqr

natita [175]

$f(x)=\sqrt{x+4}+7\\
y=\sqrt{x+4}+7\\
y-7=\sqrt{x+4}\\
(y-7)^2=x+4\\
x=(y-7)^2-4\\
f^{-1}(x)=(x-7)^2-4\ \text{ for } x\geq4$
