Answer:

z=-4.5 , MC=21

Step-by-step explanation:

AC=AM+MC

42=3-4x+3-4x ( since M is the mid point then AM=MC=3-4x)

42=6-8x

42-6=-8x

-8x=36

x=-36/8

x=-4.5

AM=MC=3-4x

MC=3-4(-4.5)= 3+18=21

MC=21

Solve the equation.<br> 25.14 = d + (-15.3)<br> 0 40.44<br> 0 -9.84<br> O 9.84<br> -40.44
Gnom [1K]

Answer:

d = 40.44

Step-by-step explanation:

Simplifying

25.14 = d + (-15.3)

25.14 = d + -15.3

Reorder the terms:

25.14 = -15.3 + d

Solving

25.14 = -15.3 + d

Solving for variable 'd'.

Move all terms containing d to the left, all other terms to the right.

Add '-1d' to each side of the equation.

25.14 + -1d = -15.3 + d + -1d

Combine like terms: d + -1d = 0

25.14 + -1d = -15.3 + 0

25.14 + -1d = -15.3

Add '-25.14' to each side of the equation.

25.14 + -25.14 + -1d = -15.3 + -25.14

Combine like terms: 25.14 + -25.14 = 0.00

0.00 + -1d = -15.3 + -25.14

-1d = -15.3 + -25.14

Combine like terms: -15.3 + -25.14 = -40.44

-1d = -40.44

Divide each side by '-1'.

d = 40.44

Simplifying

d = 40.44

Find the slope of the line passing through the two points.
GalinKa [24]

The fromula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

a) (-1, -8), (-7, -4)

substitute

m=\dfrac{-4-(-8)}{-7-(-1)}=\dfrac{-4+8}{-7+1}=\dfrac{4}{-6}=-\dfrac{2}{3}

b) (2.1, 3.8), (3.1, 7.6)

substitute

m=\dfrac{7.6-3.8}{3.1-2.1}=\dfrac{3.8}{1}=3.8

Help me please for the brainliest answer
AveGali [126]

Answer with Step-by-step explanation:

a) {n}^{2}  + 3 \\  \\ n = 1 \\  {1}^{2}  + 3 \\ 1 + 3 \\  = 4 \\  \\ n = 2 \\  {2}^{2}  + 3 \\ 4 + 3 \\  = 7 \\  \\ n = 3 \\  {3}^{2}  + 3 \\ 9 + 3 \\  = 12 \\  \\ n = 4 \\  {4}^{2}  + 3 \\ 16 + 3 \\  = 19 \\  \\ n = 10 \\  {10}^{2}  + 3 \\ 100 + 3  \\  = 103

In this sequence,

1st term = 4

2nd term = 7

3rd term = 12

4th term = 19

10th term = 103

b)2 {n}^{2}  \\  \\ n = 1 \\ 2 \times  {1}^{2}  \\ 2 \times 1 \\  = 2 \\  \\ n = 2 \\ 2 \times  {2}^{2}  \\ 2 \times 4 \\  = 8 \\  \\ n = 3 \\ 2 \times  {3}^{2}  \\ 2 \times 9 \\  = 18 \\  \\ n = 4 \\ 2 \times  {4}^{2}  \\ 2 \times 16 \\ =   32 \\  \\ n = 10 \\ 2 \times  {10}^{2}  \\ 2 \times 100 \\  = 200

in this sequence,

1st term = 2

2nd term =8

3rd term = 18

4th term =32

10th term = 200
