Answer:

$d)\ \frac{81}{m^{7}}$

Step-by-step explanation:

$(3m^-4)^3(3m^5)$

First, simplify $(3m^{-4})^3$ :

$(3m^{-4})^3\\\\3^3*m^{-4*3}\\\\27m^{-12}$

$27m^{-12}*3m^5\\\\27*3 *m^{-12+5}\\\\81m^{-7}\\\\81*\frac{1}{m^{7}} \\\\\frac{81}{m^{7}}$

Hope this helps!

Solve 2(x-3)>-3(-3+x) (Picture added, multiple choice)

Rudiy27

Answer:

Answer: D

Step-by-step explanation:

$2(x - 3) \geqslant - 3( - 3 + x)$

open the brackets [ distributive property ]

$2x - 6 \geqslant 9 - 3x$

collect like terms:

$2x + 3x \geqslant 9 + 6 \\ 5x \geqslant 15$

divide either sides by 5:

$\frac{5x}{5} \geqslant \frac{15}{5} \\ \\ { \underline{ \bf{ \: \: x \geqslant 3 \: \: }}}$

Which equation represents a proportional relationship that has a constant of proportionality equal to –10?

aksik [14]

Answer:

y = - 10x

Step-by-step explanation:

The equation representing a proportional relationship is

y = kx ← k is the constant of proportionality

y = - 10x ← is the only equation in this form

Thus the equation is y = - 10x with k = - 10

Solve the equation. 3g - 49 = 7

Alex777 [14]

Answer:

G= 56/3

Step-by-step explanation:

56/3 is an ugly number if you ask me but it was the answer I got, and here's how I got it!

So first off you want to change -49 to a positive and add it to 7! This will change the equation to 3g=56, from here just divide 56 by 3! Which if you don't turn into a fraction it'll just be a really long number. So g=56/3! If you have any more questions feel free to ask!
