Answer:
<h3>Each of the given pairs is not a solution to the given equation.</h3>
Step-by-step explanation:
Put the x and y values in the equation 4y = -7x + 5 and check the equality of the left and right side of the equation.
A. x = -5 and y = 0
L = 4(0) = 0
R = -7(-5) + 5 = 35 + 5 = 40
L ≠ R
B. x = -3 and y = 4
L = 4(4) = 16
R = -7(-3) + 5 = 21 + 5 = 26
L ≠ R
C. x = 1 and y = 3
L = 4(3) = 12
R = -7(1) + 5 = -7 + 5 = -2
L ≠ R
D. x = 2 and y = -2
L = 4(-2) = -8
R = -7(2) + 5 = -14 + 5 = -9
Answer:
y = 2x
the rise is the 2, and the the run is positive 1, because with graphing its always rise/run, and if there isn't anything below it, it is 2x/1
Answer:
the first one
Step-by-step explanation:
1. 1310 x 0.15 = 196.5
2. 1310 - 196.5 = 1113.5
3. 1113.5 - 310 = 803.5
4. 803.5 - 405 = 398.5
5. 398.5 divided by 2 = 199.25
Answer:
It takes 7.37 hours for the size of the sample to double.
Step-by-step explanation:
Continuous exponential growth model:
The continuous exponential growth model for populations is given by:
In which P(0) is the initial population and r is the growth rate parameter, as a decimal.
Growth rate parameter of 9.4% per hour.
This means that
So
How many hours does it take for the size of the sample to double?
This is t for which P(t) = 2P(0). So
It takes 7.37 hours for the size of the sample to double.
