What we're dealing with is the Distributive Property. This allows any number/variable outside of a parenthesis to multiply by all numbers/variables inside of the parenthesis.
For example:
2(1 + 3)
2(1) + 2(3)
2 + 6
8.
Now that we've broken down what we're dealing with, let's try to solve.
-3(b + 19) = -12
-3(b) + -3(19) = -12
-3b -57 = -12
Add 57 to both sides to get -3b by itself.
-57 + 57 = 0
-12 + 57 = 45
-3b = 45
Divide both sides by -3 to solve for b.
-3b / -3 = b
45 / -3 = -15
b = -15

(3, 6) can replace the missing value and create a function
Step-by-step explanation:
Given relation is:
{(8,5), (2, 3), (1,6), (7,4), _?_}
In order for a relation to be a function, the first condition is that there should be no repetition in domain of the function i.e. same input cannot map to multiple outputs.
In the form of ordered pairs, the first element of each ordered pair represents the elements of domain set
So,
From all the option given, only (3,6) is suitable to be put in the blank space as it will create no repetition in the domain while other ordered pairs will cause repetition.
Hence,
(3, 6) can replace the missing value and create a function

Log2 (8)= 3
Log6 (216) = 3
Log4 (2)= 0.5
Logb (N)= x
Log10 (y) =x
Answer:
y = -53x
Step-by-step explanation:
since 0,0 is a point, there is no b, and -5/3 times 3 is -5
