the midpoint of a horizontal line segment is at x=1 if the length of the line segment is 10.5. what absolute value equation coul
egoroff_w [7]

Answer: -4.25 ≤ x ≤ 6.25

Step-by-step explanation:

The midpoint of a segment is located at the same distance of each of the endpoints of the segment.

The midpoint is at x = 1.

The length of the segment is 10.5, if we divide it by two we have:

10.5/2 = 5.25

Now, if we want the endpoints to be at the same distance of the midpoint, then the endpoints will be:

Xmax = midpoint + 5.25

Xmin = midpoint - 5.25

Then the extremes are:

Xmax = 1 + 5.25 = 6.25

Xmin = 1 - 5.25 = -4.25

Then this segment can be written as:

Xmin ≤ x ≤ Xmax

-4.25 ≤ x ≤ 6.25

.. Discuss the nature of the root of equation x2 + 2x + 3 = 0​
Mariana [72]

Answer:

  • No real roots

Step-by-step explanation:

Given equation:

  • x² + 2x + 3 = 0

On comparing the equation by ax² + bx + x = 0, We get: a = 1, b = 2 and c = 3

To Find the nature of the roots of the equation firstly we need to find the discriminant of the equation. The expression b²- 4ac is called the discriminant.

~

  • Two Distinct real roots, if b² - 4ac > 0
  • Two equal real roots, if b² - 4ac = 0
  • No real roots, if b² - 4ac < 0

\\ \: \: \dashrightarrow \: \: \: \sf  {b}^{2} - 4ac = 0 \\ \\ \\\: \: \dashrightarrow \: \: \: \sf (2)² - 4 \times 1 \times 3 = 0 \\  \\  \\ \: \: \dashrightarrow \: \: \: \sf 4 - 4 \times 1 \times 3 = 0  \\  \\  \\ \: \: \dashrightarrow \: \: \: \sf 4 - 12 = 0 \\  \\  \\ \: \: \dashrightarrow \: \: \: \sf {\underline{\boxed{\sf{\purple{  -8 > 0}}}}} \\  \\

The discriminant is smaller than 0.

  • <u>Hence, Equation has no </u><u>real</u><u> roots (no solution)</u>

Can someone help me, please ?? im stuck 
Tresset [83]

Part A

5x - 5 >= 10 or-3x + 1 > 13

1) This is a disjunction (OR)

5x - 5 >= 10

5x >= 15  

 x >= 3

or

-3x + 1 > 13

-3x > 12

  x < -4

Answer

x <- 4 or x >= 3


Part C:

1) This is a conjunction (And)

5x+ 3 <= 18 and 4 - x < 6

5x <= 15       and  - x < 2

 x <= 3    and        x > -2

Answer

-2 < x <= 3
