Answer:
It's simple.
Step-by-step explanation:
Inequalities that use < or > symbols are plotted with a dashed line to show that the line is not included in the region. Inequalities that use ≤ or ≥ symbols are plotted with a solid line to show that the line is included in the region.
The first choice,
... a. s(t) = ac[1 + μam cos (2πfmt)] cos (2πfct)
has the carrier frequency cos(2πfct) amplitude modulated by the message signal.
The other expressions represent frequency and phase modulation of various kinds.
0.2, 0.75, 60%, 1/2, 1, 1 1/4
60% is the same as 60/100 or 0.6
1 1/4 is the same as 5/4 or 1.25
1/2 is the same as 0.5
Now our list is
0.2, 0.75, 0.6, 0.5, 1.25 and 1
So from largest to smallest your answer would be...
1.25 , 1 , 0.75 , 0.6 , 0.5 , 0.2
Answer:
x=-2
Step-by-step explanation:
Cross multiplication
6(7x+4)=5(5x-2)
42x+24=25x-10
17x=-34
x=-2
