Answer:

EK = 9

Step-by-step explanation:

x + 11 = -5 + 2x -5 + 2x

x+11 = -10 + 4x

11 = 3x - 10

3x = 21

x = 7

EK =-5 + 2 × 7

EK = 14 - 5

EK = 9

Artyom0805 [142]

Answer:

9. First Five terms

If n=0. Then,

$\frac{4(0) - 5}{2}$

$\frac{0 - 5}{2} = \frac{ - 5}{2}$

If n=1. Then,

$\frac{4(1) - 5}{2}$

$\frac{4 - 5}{2} = \frac{ - 1}{2}$

If n=2. Then,

$\frac{4(2) - 5}{2}$

$\frac{8 - 5}{2} = \frac{3}{2}$

If n=3. Then,

$\frac{4(3) - 5}{2}$

$\frac{12 - 5}{2} = \frac{7}{2}$

If n=4. Then,

$\frac{4(4) - 5}{2}$

$\frac{16 - 5}{2} = \frac{11}{2}$

If n=5. Then,

$\frac{4(5) - 5}{2}$

$\frac{20 - 5}{2} = \frac{15}{2}$

If n=6. Then,

$\frac{4(6) - 5}{2}$

$\frac{24 - 5}{2} = \frac{19}{2}$

Write an equation in point slope form for each line<br> Slope is 3 and (-2,-1) is on the line

elena-14-01-66 [18.8K]

Answer:

$\huge \blue{y + 1 = 3(x + 2) } \\$

Step-by-step explanation:

To find an equation of a line in point slope form when given the slope and a point we use the formula

$y - y_1 = m(x - x_1)$

From the question we have the final answer as

$y + 1 = 3(x + 2)$

Hope this helps you
