Answer:
-5
Step-by-step explanation:
9x +18=-27
9x = -27 -18
9x =-45
x = -45/9
x = -5
x= the number
<span>To find the range of this function, simply plug each of the end values into the original equation. In this case, with x of -2, the function becomes f(x) = 6+1 or 7, and with x of 7, the function becomes f(x) = -21+1 or -20. As such, the range of the function is -21 <= f(x) <= 7.</span>
0.4=40%
75%=3/4
0.64=16/25
30%=0.3
3/20=15%
Answer:
