If point B is the midpoint of points A and C, find the value of x and AC. AB= 5x - 2, BC= 9x -10

mars1129 [50]

9514 1404 393

Answer:

x = 2
AC = 16

Step-by-step explanation:

The midpoint divides the segment into two equal lengths:

AB = BC

5x -2 = 9x -10

8 = 4x

2 = x

AB = 5(2) -2 = 8

AC = 2AB = 2(8) = 16

Choose the third degree polynomial. 2x-5 3x2+2x-5 x3-3x2+2x-5 5x4+x3-3x2+2x-5

Bess [88]

ANSWER

${x}^{3} - 3 {x}^{2} + 2x - 5$

is the third degree polynomial.

EXPLANATION

The third degree polynomial has the highest degree to be 3.

All the polynomials were written in standard form.

$2x - 5$

is a first degree polynomial.

$3 {x}^{2} + 2x - 5$

is a second degree polynomial .

${x}^{3} - 3 {x}^{2} + 2x - 5$

is a third degree polynomial.

$5 {x}^{4} + {x}^{3} - 3 {x}^{2} + 2x - 5$

is a fourth degree polynomial.
