Answer:

The slope of the line passing through the points (-4, 8) and (2,8) is 0

Step-by-step explanation:

The slope is 0 because you would subtract the y ones first 8-8, subtract the x ones next 2-(-4). You would get 0/6. When you would divide 0/6, you would get 0

Answer:

Step-by-step explanation:

The formula of a midpoint:

$M\left(\dfrac{x_1+x_2}{2};\ \dfrac{y_1+y_2}{2}\right)$

We have A(0, 0) and C(2a, 2b). Substitute:

$x=\dfrac{0+2a}{2}=\dfrac{2a}{2}=a\\\\y=\dfrac{2b+0}{2}=\dfrac{2b}{2}=b$

Softa [21]

Answer:

(4,14) because both lines pass through it.

Step-by-step explanation:

A "solution" to a system of equations is simply a point that both lines pass through.

First image is the solution found through graphing and the second image is the solution found through substitution.

The 8th term in the arithmetic sequence is 17, the 12th term is 25. Find the first term, and the sum of the first 20 terms.

Trava [24]

Answer:

First term a = 3

Sum of first 20 term = 440

Step-by-step explanation:

Given:

8th term of AP = 17

12th term of AP = 25

Find:

First term a

Sum of first 20 term

Computation:

8th term of AP = 17

a + 7d = 17 ....... EQ1

12th term of AP = 25

a + 11d = 25 ...... EQ2

From EQ1 and EQ2

4d = 8

d = 2

a + 7d = 17

a + 7(2) = 17

First term a = 3

Sum of first 20 term

Sn = [n/2][2a + (n-1)d]

S20 = [20/2][(2)(3) + (20-1)2]

S20 = [10][(6) + 38]

S20 = [10][44]

S20 = 440

Sum of first 20 term = 440
