Answer:
-3 and 11
Step-by-step explanation:
I basically drew a t-chart and I knew that -33 is the product (mutiplies to) and 8 is what it adds to. The only numbers that work are -3 and 11 because it says positive 8. -3 and 11 add to +8. Hope this helps!
Pretty sure it's x= -2. multiply everything by 3
then combine.
10= 6^x you can work it like a log and minus 10 from each side.
0= -4^x
so what raised to the power gives you -4? x=-2
