The exponent indicates how many times the base is used as a factor.
-3x+2 < 8
-2 -2
-3 /-3x <6/-3
x >-2
So x>-2
Answer:
18. Its 2 meters.
19. Its 0.2 grams
20. Its 1,920
Step-by-step explanation:
When you convert 200 centimeters to meters its 2.
When you convert 2,000 milligrams in grams its 0.2
15% of 12, 800 is 1,920
Hope this helps:)
For #2:
<span> 3x^2 + 4 – 2x^2 + 6</span>
<span><span>You need to combine your like terms:
</span>
3x^2 – 2x^2= x^2</span>
4 + 6 = 10
This will now give you:
<span>X^2 +10</span>
F(x)= 650(1+.12)^x
f(x) = 650(1.12)^x
