Solve the equation by using the basic properties of logarithms. log(2x)=3
Scilla [17]
If no base is mentioned, asssume base 10

remember
log_a(b)=c translates toa^c=b
so
since no base mentioned, assume base 10

log_{10}(2x)=3 translates to 10^3=2x then
1000=2x
divide both sides by 2,
500=x

PLEASE HELP 30 POINTS TO WHOEVER HELPS I NEED IT QUICK PLEASE HELP
Brut [27]

Answer:

Hi there!

The correct answer is:

a. 27831.05

Step-by-step explanation:

Since they gave you the equation for the line of best fit: y = 1.9x + 21

a. solve for x: 52900= 1.9x + 21

minus 21 on both sides to get 1.9x = 52879

then divide 1.9 on both sides to get x= 27831.05

In Triangle XYZ, A is the midpoint of XY, B is the midpoint of YZ, and C is the midpoint of XZ.
Roman55 [17]

The perimeter of triangle ABC is 24 units

Step-by-step explanation:

If a segment joining the mid points of two sides of a triangle, then

this segment is:

  • Parallel to the third side
  • Its length is half the length of the third side

In The triangle XYZ

∵ A is the mid point of XY

∵ B is the mid point of YZ

∴ AB = \frac{1}{2} XZ

∵ XZ = 18 units

- Substitute the value of XZ in AB

∴ AB = \frac{1}{2} × 18 = 9 units

∵ B is the mid point of YZ

∵ C is the mid point of XZ

∴ BC = \frac{1}{2} XY

∵ AY = 7 units

∵ AY = \frac{1}{2} XY

∴ XY = 2 × AY

∴ XY = 2 × 7

∴ XY = 14 units

∴ BC = \frac{1}{2} × 14 = 7 units

∵ A is the mid point of XY

∵ C is the mid point of XZ

∴ AC = \frac{1}{2} YZ

∵ BZ = 8 units

∵ BZ = \frac{1}{2} YZ

∴ YZ = 2 × BZ

∴ YZ = 2 × 8

∴ YZ = 16 units

∴ AC = \frac{1}{2} × 16 = 8 units

∵ The perimeter of a triangle = the sum of the lengths of its sides

∴ Perimeter Δ ABC = AB + BC + AC

∴ Perimeter Δ ABC = 9 + 7 + 8 = 24 units

The perimeter of triangle ABC is 24 units
