Answer:
x < 9
Step-by-step explanation:
subtract 7 from both sides of the inequality
- 4x > - 36 ( divide both sides by - 4 )
When multiplying/dividing by a negative quantity the symbol is reversed
x < 9 ← note reversal of symbol
Answer:
hello :
60x² – 155x + 100 = 5 ( 12 x² - 31 x + 20 )
delta of ( 12x² - 31 x + 20 ) is b² - 4ac when : a = 12 b = -31 c = 20
delta = ( - 31 )² - 4(12)(20) = 961 - 960 = 1
x1 = (31-1)/24 = 30/24 = 5/4
x2 = (31+1)/24 = 32/24 = 4/3
Factor 60x2 – 155x + 100 = 5 (12(x -5/4)(x- 4/3)) = 60 (x -5/4)(x- 4/3)
The best example of a plane would be A) the surface of a flat table. A plane could also be represented by anything that is flat in nature.
Hope this helps! :)
Shes is wrong because 30% of 80 is 24
329 :32=10,28125 is the answer
