Mathematics
1 answer:
Tasya [4]3 years ago
8 0

Answer:

n= -12

Step-by-step explanation:

- 2n/3  + 7=15          Subtract 7 from both sides and move all terms containing

           -7 = -7                      n to the right

- 2n/3 = 8                multiply both sides of equation by - 3/2

-3/2  x (-2n/3) = -3/2 x 8

n= -3/2 x 8                     cancel the common factor of 3

n= -12

Simplify the expression square root of -25/(5-2i) + (1-3i)
Georgia [21]

Answer:

I guess \frac{25}{6} -5i

Step-by-step explanation:

\frac{-25}{(5-2i)+(1-3i)}              1. rewrite the expression(it helps me tbh)

\frac{-25}{5 - 2i+1-3i}                   2. Distribute the positive symbol to (1-3i)

\frac{25}{6-5i}                           3. treat i as a variable while you combine like terms

\frac{25}{6} -5i                       4. divide 25 by 6-5i but leave 25/6 as a fraction since it can't be divisible.

What is the slope of line segment AB? Keep as a reduced fraction.<br> B<br> A
ladessa [460]

Answer:

2

Step-by-step explanation:

Use rise over run (y2 - y1) / (x2 - x1) where (x1, x2) and (y1, y2) are points on the line

Plug in the points A (-3, -2) and B (1, 6)

(y2 - y1) / (x2 - x1)

(6 + 2) / (1 + 3)

8 / 4

= 2

So, the slope of line segment AB is 2.
