Answer: X = 2.28
Step-by-step explanation:
-31 from both sides (The positive 31 and 63)
= 14x = 32 then divide both sides by 14
14x divided by 14 is x and 32 divided by 14 is like 2.28
x=2.28
Answer:
7x+12 because there is 8x then you subtract 1x which 'll equal 7x and add the 12
Replace x with 3:
f(x) = 20(0.5)^x
f(3) = 20(0.5)^3
First do 0.5^3 = 0.125
Now multiply that by 20:
20 x 0.125 = 2.5
f(3) = 2.5
240000
2
2(9 + 7) = 2*9 + 2*7 = 18 + 14
So it is a.
