15 × h
h= per hour
and to solve how many hours it would take:
600= 15 × h
600÷ 15 = 40
so it would take 40 hours to rise to the surface
Answer:
Step-by-step explanation:
They are both straight lines. Function A has slope -5
Function B has slope -4.5
-4.5 > -5
B has the greater rate of change.
120 = 2x + x
120 = 3x
120/3 = x
40=x <- Solved for how many cds april has.
Since amy has twice as many cds, she would have 80 cds
The x- intercept is where y = 0 on the graph and the y- intercept is where x= 0 on the graph. When X=0, all the terms, except for the constant are equal to zero, thus the y- intercept is the constant. y=10 when x=0. Use the quadratic formula to find the x value where y=0.
x= (-b +or- sqrt(b^2 -4ac))/2a
y=ax^2 +bx +c
The answer for the x- int is imaginary. This happens because 10 is the parabola's minimum value and it never touches the x- axis. y-int is 10
