harina [27]

Answer:

$\boxed{\frac{-3b^4 }{a^6 }}$

Step-by-step explanation:

$\frac{-18a^{-8}b^{-3}}{6a^{-2}b^{-7}}$

$\frac{-18}{6} \times \frac{a^{-8}}{a^{-2}} \times \frac{b^{-3}}{b^{-7}}$

$-3 \times \frac{a^{-8}}{a^{-2}} \times \frac{b^{-3}}{b^{-7}}$

Apply the law of exponents, when dividing exponents with same base, we subtract the exponents.

$-3 \times a^{-8-(-2)} \times b^{-3- (-7)}$

$-3 \times a^{-8+2} \times b^{-3+7}$

$-3 \times a^{-6} \times b^{4}$

${-3a^{-6}b^{4}}$

The answer should be without negative exponents.

$a^{-6}=\frac{1}{a^6 }$

$\frac{-3b^4 }{a^6 }$

There are two similar triangles on the graph below use the graph to answer the questions you must answer each question and expla

Alona [7]

Answer:

we can use similarity of triangles in this case there will be formation of 2 pairs of equal (eg:-angle formed by the y- axis on the parallel lines) angles between triangles formed as the y- axis lines are parallel. So,slope of the graph between points A and B is the same as the slope of the graph between points A and B.

What is the common ratio for the geometric sequence? 4/3,4,12,36,...

Jobisdone [24]

3 is the correct answer

u can find common ratio by dividing a specific term in GP by its preceding term. ...just as here
4/(4/3) = 3

also 12/4 = 3

also 36 /12 = 3

hence the common ratio for this GP is 3

hope it helped
