Answer:
B = log₃243 = 5
Step-by-step explanation:
By using the rule of aⁿ = b ==> logₐb = n, you can transform the exponent form into a logarithmic form by switching around the values of each letter to their desired place. It is interchangable between the two equations.
Answer:
2 distinct solutions
Step-by-step explanation:
discriminant is b²-4ac
b = 3
a = 1
c = -7
discriminant = 9-4(-7) = 9+28 = 37
Answer: Each hamburger cost $3.50
Step-by-step explanation:
He spent $13 in total and bought one hot dog for $2.50 and 3 hamburgers but we don't know the price of one hamburger so we could represent it by the equation,
2.50 + 3h = 13 Now solve for x
-2.50 2.50
3h = 10.50
h = 3.50
Check:
2.50 + 3(3.50) = 13
2.50 + 10.50 = 13
13= 13
