Answer:
x = -48
Step-by-step explanation:
-4(7.5x - 8) = -5(6.3x + 8)
-30x + 32 = -31.5x - 40
-30x + 31.5x = -40 - 32
1.5x = -72
x = -72/(1.5)
x = -48
<h2>♪Answer : </h2>
Ingat rumus determinan fungsi kuadrat yaitu :

Maka, Kita kembali jawab soalnya.
⏩Nomor (1) :
»8x² + 7x + 10 = 0
Didapatkan nilai² a, b, dan c yaitu :
Maka, nilai determinannya adalah
- D = b² - 4ac
- D = 7² - 4(8)(10)
- D = 49 - 4(80)
- D = 49 - 320
- D = -271✅
⏩Nomor (2) ;
»2x² + 10x + 10 = 5
»2x² + 10x + 10 - 5 = 0
»2x² + 10x + 5 = 0
Didapatkan nilai² a, b, dan c yaitu :
Maka, nilai determinannya adalah
- D = b² - 4ac
- D = 10² - 4(2)(5)
- D = 100 - 4(10)
- D = 100 - 40
- D = 60✅

Hope it helps you:)
Answer:
no real numbers will make this equation true
Step-by-step explanation:
if you square both sides, you'll get sqrt(-49). this will get you an imaginary number (7i) which is not a real number.
