Answer:
Step-by-step explanation:
4*3^x+1=27+(3^2)^x
(3^2)^x=(3^x)^2
3^x=t
4t+1=27+t^2
t^2-4t+27-1=0
t^2-4t+26=0
delta=4^2-4*1*26=16-84=-68<0
the equation has not real solutions
2.4 minus 1.57 = 0.83
Therefore, the answer is 0.83
126 car owners were not completely satisfied with their purchase.
If we add 32 and 24, that would give us 56. This problem represents the total amount of people who gave a review.
Then we would take 184, and subtract it by 56. That would give us 126. The 56 represents the amount of people who didnt exactly give a negative survey result, we still dont know how many gave a negative result, therefore we subtract the amount of people who has already submitted a complete and "positive" survey, to the overall amount of people that has bought a car.
Answer:
y=11
Step-by-step explanation:
1.) isolate the variable and coeffient by subtracting 10 from both sides to get 22=2y
2.) do the inverse operations to get y by itself so 22 divided by 2 which equals 11
3.) y=11
