Since x is less than 0 we have to use -2x.
Substitute -3 for x.
f(x) = -2(-3)
f(x) = 6
Remember, you can do anything to an equation as long as you do it to both sides
minus 1 both sides
7x=35
divide both sides by 7
x=5
Answer:
the percent of 69/150 is 46%
0.7 1.4 1.8 2.2 3.9
Look first of all at the units place. The choices are 0 1 2 and 3
the 0 place is going to come first. Then the 1s (both of them) and the 2 and then 3.
Now look at the tenths place. The two where that matters is 1.4 and 1.8.
1.4 < 1.8 so the order is 1.4 followed by 1.8
Your answer would be (B) 4.94. Hope this helped!
6.44 + 8.62 = 15.06
20 - 15.06 = 4.94
