Does 3x-2+x+8=1/2(9x+7-x+5) have no solution or infinite solutions

Mathematics

kupik [55]4 years ago

Answer:

Step-by-step explanation:

3x - 2 + x + 8 = ( 9x + 7 - x + 5)/2

Add the like terms

4x + 6 = 8x + 12/2

Cross multiply or multiply both side by two

2(4x + 6) = 8x + 12

Use 2 to open the bracket

8x + 12 = 8x + 12

Collect like terms

8x - 8x = 12 - 12

0 = 0

Therefore, the equation has no solution

4. A map of an amusement park is shown on a coordinate plane, where each square
Zielflug [23.3K]

Using cartesian coordinates concepts such as midpoint and distance between two points, it is found that:

  • The location point of the Ferris wheel is (15,24).
  • They need to walk 20 units.
  • The coordinates of the hotdog stand are (23,8).

  • Water ride is at point (3,8).
  • Roller coaster is at point (27,40).
  • The Ferris wheel is at the midpoint of the water ride and the roller coaster, thus it's coordinates are the <u>mean of their coordinates.</u>

x = \frac{3 + 27}{2} = 15

y = \frac{8 + 40}{2} = 24

The location point of the Ferris wheel is (15,24).

The distance between two points, (x_1,y_1) and (x_2,y_2) is given by:

D = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

Here, Tiffany and her sister are at (15,24) while their parents are at (3,8). Thus, their distance is:

D = \sqrt{(15 - 3)^2 + (24 - 8)^2} = 20

They need to walk 20 units.

  • Hotdog stand is directly east of the water ride, thus, it has the <u>same y-coordinate, while the x-coordinate is increased</u>.
  • The distance is of 20 units, thus:

(3 + 20, 8) = (23,8)

The coordinates of the hotdog stand are (23,8).
