Replace x with 3 and solve:
10 x 5^3
Simplify:
10 x 125 = 1250
Answer: y = 1250
Function 1
rate of change = (80-100)/(2-1) = -20
y = -20x + 120
function 2
y = -18x + 120
rate of change = -18
answer
function 2 shows a greater rate of change
Answer:
You didnt give any options, but I'm guessing one of them has a 3 in the tens digits, which should be the right answer.
Step-by-step explanation:
Answer:
The equation is;
y = -1/4x + 607.5
Step-by-step explanation:
Let us have the number of drops as y axis while the number of minutes is x axis
The points to use are;
(30,600) and (130,575)
The slope can be calculated using;
m = (y2-y1)/(x2-x1)
= (575-600)/(130-30) = -25/100 = -1/4
So the equation as we model using the normal equation of a straight line (y = mx + c, m is slope and c is the intercept)
y = -1/4x + c
To get c, we simply substitute one point
Let us use (30,600)
We have
600 = -1/4(30) + c
600 + 7.5 = c
c = 607.5
So the equation is ;
y = -1/4x + 607.5
The answer is D. 22.1.
Hope this helps!! Have a good Day!!! :D
