We move all terms to the left:
7x-19-(x+5)=0
We get rid of parentheses
7x-x-5-19=0
We add all the numbers together, and all the variables
6x-24=0
We move all terms containing x to the left, all other terms to the right
6x=24
x=24/6
x=4
We have that the <em>exponential growth function</em> and population be in 2020 is mathematically given as
- y=325000e^{0.002t}
- y=469925
From the question we are told
- The population of a city has been increasing by 2% annually. The sign shown is from the year 2000.
- Write an exponential growth <em>function</em> that represents the population t years after 2000.
- What will the population be in 2020? Round your <em>answer</em> to the nearest thousand. The popu<em>l</em>ation will be about:
<h3>
Population</h3>
a)
Generally the equation for the standard form of exponential <em>function</em> is mathematically given as
y=325000e^{0.002t}
b)
With T =20
Hence
y=325000e^{0.002(20)}

Answer:
(-2, 3), (.5, 3), (-4, -2), (-3)
Step-by-step explanation:
Lo siento, pero no hablo espanol bien. Usas un traductor, por favor.
A in the formula is going to be the coefficient for the x^2 term.
B in the formula is going to be the coefficient for the x term.
C in the formula is going to be the constant.
I will show you how to do A.
-b = 1
b^2 = 1
-4ab = -24
1 - -24 = 25
1 = 6, -4
2a = 2
6/2 = 3
-4 / 2 = -2
(-2, 3)
Answers:
A: 12 1/15
B: -2 1/7
C: -6 14/15
D: -2 1/12
(2nd)C: -11/4
Good luck and have a blessed evening!
Answer:
13- A 14-B
Step-by-step explanation:
You take the formula (x1+x2/2, y1+y2/2) and plug in accordingly. For instance, when you plug the values in for 13, you would get:
x1+-9/2, y1+7/2= -8,2
All you have to do from there is a simple guess and check or plug in each number from the multiple answer choices you have. You should then get A (-7,-3) Do the same with 14, in which you should get B (11,-20)
Sorry for taking so long to answer but hope this kind of helps.
