Write the product using exponents -3/7×3/7×3/7<br>​
zlopas [31]

Answer:

-(\frac{3}{7})^3

Step-by-step explanation:

Since we see that 3/7 is multiplied by itself three times, we can use exponents as a shorter way to write this. The expontent tells us how many times the base number, 3/7, is multiplied by itself.

-1 * (\frac{3}{7})^3= -1 * \frac{3}{7} *  \frac{3}{7} * \frac{3}{7}

We then multiply by -1 to (3/7)^3 to get the exact answer.

-(\frac{3}{7})^3

Write the equation of the line that passes through (5.-9) and (2.5).
Kipish [7]

Answer:

y = -14/3x + 43/3

Step-by-step explanation:

y2 - y1 / x2 - x1

5 - (-9) / 2 - 5

14 / -3

- 14/3

y = -14/3x + b

5 = -14/3(2) + b

5 = -28/3 + b

43/3 = b

y = -14/3x + 43/3
