Since there is a negative correlation, evident by the negative slope of the equation of the line given to be -0.5, if we take t as 0, we get an equation of,
s = 3.6
This means that if a student does not watch television, he or she spends a maximum of 3.6 hours studying.
The answer is the first answer choice
Answer:
the answer is $22.32
Step-by-step explanation:
when x= -4 ,f(x)=2
Step-by-step explanation:
the coordinate in which f(x) i.e y=2 is (-4,2)
thus x= -4
Answer:
x = ± 2
Step-by-step explanation:
Given
f(x) = x² + 1 and (x, 5 ) is a solution then f(x) = 5
Equating the two gives
x² + 1 = 5 ( subtract 1 from both sides )
x² = 4 ( take the square root of both sides )
x = ± 
= ± 2
Thus (- 2, 5) and (2, 5) are solutions
