Answer: dot know srry
Step-by-step explanation:
Let A and B represent the number of hours that plans A and B last, respectively. Then the problem statement tells you
7A +9B = 12
5A +3B = 6
There are many ways this set of equations can be solved. I find it fairly simple to use a graphing calculator. The one shown tells me the workouts are each 3/4 of an hour.
Plan A lasts 45 minutes (3/4 hour)
Plan B lasts 45 minutes (3/4 hour)
162/60 = 2.7 heartbeats per second
Answer and Step-by-step explanation:
1. slope intercept
2. point-slope form
3. standard
Explanation:
1.
A <u>slope intercept form</u> equation is when it's set up as y = m x + b
m = slope
b = y-intercept
2. <u>A point-slope form</u> is when a line passes through a point
and the equation is set up as y
−b = m (
x−a)
m = slope
(a, b) A point that the line passes through
3. <u>standard lope form</u> is when the equation is set up as
Ax + By = C
Y = a (b^x)
1) x = 0, y = 3500
=> 3500 = a (b^0)
=> 3500 = a (1)
=> a = 3500
2) growth percent = 3.5% => growth rate = 1.035 = b
=> y = 3500 (1.035)^ x
3) year 2020 => x = 2020 - 2000 = 20
4) y = 3500 (1.035)^ 20 = 6964
Answer: 6964.
