1. First transformation is rotation rotation of 180 about the origin. This transformation has a rule:

(x,y)→(-x,-y).

If points E(-2,-4), F(-1,-1), D(-2,-1) are vertices of triangle EFD, then

  • E(-2,-4)→E''(2,4),
  • F(-1,-1)→F''(1,1),
  • D(-2,-1)→D''(2,1).

2. Second transformation is translation 1 unit left with a rule

(x,y)→(x-1,y).

Then

  • E''(2,4)→E'(1,4),
  • F''(1,1)→F'(0,1),
  • D''(2,1)→D'(1,1).

Answer: 1st: rotation of 180 about the origin; 2nd: translation 1 unit left.

Solve -2(5x – 3) = 41.<br> need help
navik [9.2K]

Answer:

x = -7/2

Step-by-step explanation:

-2(5x - 3) = 41

Distribute the -2 inside the parenthesis.

-10x + 6 = 41

Subtract 6 from both sides.

-10x = 35

Divide both sides by -10.

x = 35/-10

Simplify the fraction.

x = -7/2.

Proof:

-2(5x - 3) = 41

Substitute variable.

-2(5(-7/2) - 3) = 41

Multiply 5 and -7/2.

-2(-35/2 - 3) = 41

Turn 3 into a fraction with denominator 2.

-2(-35/2 - 6/2) = 41

Subtract 6/2 from -35/2.

-2(-41/2) = 41

Multiply -2 and -41/2.

41 = 41.

3x²-24x + 12<br><br><br> What’s the factor of
Tems11 [23]

Answer:

<u>[x - (4 + 2√3)] and [x - (4 - 2√3)]</u>

Step-by-step explanation:

Given :

  • 3x² - 24x + 12

Divide throughout by 3 to simplify :

  • 1/3 x (3x² - 24x + 12)
  • x² - 8x + 4

Using the Quadratic Formula :

  • x = -b ± √b² - 4ac / 2a
  • x = -(-8) ± √(-8)² - 4(1)(4) / 2(1)
  • x = 8 ± √64 - 16 / 2
  • x = 8 ± √48 / 2
  • x = 8 ± 4√3 / 2
  • x = 4 ± 2√3

Factors are :

  • <u>[x - (4 + 2√3)] and [x - (4 - 2√3)]</u>

Answer:

0.03 seconds

Step-by-step explanation:

10,000km = 300secs

1km = x seconds

Cross multiply the equation

10,000x = 300

Divide both sides by 10,000

<u>1</u><u>0</u><u>,</u><u>000x</u> = <u>3</u><u>0</u><u>0</u>

10,000 10,000
