The Hollywood cats are a group of cats that have settled in along the Hollywood Beach in Florida. A group of volunteers feed them and care for them while trying to humanely reduce their numbers (as they are considered a nuisance). If there were 100 cats in the year 2012 and the rate of population change is given
by [tex]-\frac{1}{4} t-2[/tex]
where t is measured in years, how many cats are projected to be in the group in 2020.
Answer:
The number of total cats left after 8 years T
[tex]T=76[/tex]
Step-by-step explanation:
From the question we are told that
Number of cats 2012 n=100
Number of years t=2012-2020=>8 years
Generally the equation of change in population is mathematically Given as
[tex]\frac{dp}{dt}= -\frac{1}{4} t-2[/tex]
[tex]\int dp=\int_0^8 (-\frac{1}{4} t-2)[/tex]
[tex]p=\frac{-64}{8} -16[/tex]
[tex]p=-24cats[/tex]
Therefore the number of total cats left after 8 years T is given as
[tex]T=100-24[/tex]
[tex]T=76[/tex]

The equation 3x + 2 = 29 is modeled below.
Which is the first step in solving the equation for x?
Answer:
Subtract 2 from both sides.
Step-by-step explanation:
Remember to do the opposite of PEMDAS. PEMDAS is the order of operation, and stands for:
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
> Also, note the equal sign, what you do to one side, you do to the other side of the equation.
First step is to subtract 2 from both sides of the equation:
3x + 2 (-2) = 29 (-2)
3x = 29 - 2
3x = 27
The second step is to divide 3 from both sides of the equation:
(3x)/3 = (27)/3
x = 27/3
x = 9
~
Answer:
The first step is subtracting the two on both sides.
Step-by-step explanation:
You arent exactly following PEMDAS in this equation, but you are still in a way. Before going on to x you need to go on to the numbers first. 3x would be equal to 27.

PLS MARK AS BRAINLIEST!
Answer:
-1
Step-by-step explanation:
3 times a which a is 5 it becomes 15 and
2 times b which b is -4 it becomes -16
so 3*5 + 2*(-4)=
15+(-16) and cause plus and minus gives you minus so
15-16= -1
usebthe elimination method to solve the following system of equations
4x+y=13
5x-y=5
Answer:
x = -2, y = 21
Step-by-step explanation:
Let 4x + y = 13 to be equation1 {eqn1}
and let 5x - y = 5 to be equation2 {eqn2}
Using elimination method, you would try to make sure a particular unknown has the same value in both equation 1 and 2. This would make it easy for you to subtract one equation from the other.
Notice how the value of y is the same in both equations. That's a good sign.
But the signs aren't the same. Meaning y in eqn1 has a value of +1, and y in eqn2 has a value of -1. We need to make them similar.
So, we multiply the value of y in eqn1 by all the terms in eqn2. And, do pretty much the same thing by multiplying the value of y in eqn2 by all the terms in eqn1.
You would have:
-1 * (4x + y = 13)
+1 * (5x - y = 5)
This would result in;
-4x - y = -13 (eqn3)
5x - y = 5 (eqn4)
So, just subtract eqn3 from 4
You would have;
(5x - -4x) + (-y -- y) = (-13 - 5)
9x + 0 = -18
x = -18/9 = -2
and to find y;
just substitute the value of x into any of the 4 equations. let's try equation 1
Therefore;
4(-2) + y = 13
-8 + y = 13
y = 13 + 8 = 21

The sum of all the solutions of the equation (6x+k)(3x-11)=0 is 1. Find K
BRANLIEST PLUS 20 POINTS
Answer:
16
Step-by-step explanation:
6x+k = 0
x = -k/6
3x-11 = 0
x = 11/3
-k/6 + 11/3 = 1
k - 22 = -6
k = 16
The value of k is "8".
Find K:[tex](6x+k)(3x-11)=0\ \ is \ \ 1 \\\\K=?[/tex]
[tex]\to (6x+k)(3x-11)=0 \ \ is \ \ 1 \\\\\to (6x+k)=0\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ and \ \ \ \ \ \ \ \ \ \ \ \ \ \ (3x-11)=0\\\\\to 6x=-k\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ and \ \ \ \ \ \ \ \ \ \ \ \ \ \ 3x=11\\\\\to x=-\frac{k}{6}\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ and \ \ \ \ \ \ \ \ \ \ \ \ \ \ x=\frac{11}{3}\\\\[/tex]
[tex]\to - \frac{k}{6}+ \frac{11}{3}=1\\\\\to \frac{-2k+ 22}{6}=1\\\\\to -2k+ 22=6\\\\\to -2k =6-22\\\\\to -2k =-16\\\\\to k=\frac{16}{2}\\\\\to k=8[/tex]
Therefore, the final value of k is "8".

which is the best deal: a 14 ounce drink for $4.50 or a 12 ounce drink for $3.75?
Answer: 12 ounces for $3.75 is the better value
Step-by-step explanation:
The 12-ounce drink for $3.75 is the best deal as it has a lower cost per ounce compared to the 14-ounce drink for $4.50.
To find the best deal, we need to compare the cost per ounce for each drink.
For the 14-ounce drink:
Cost per ounce = $4.50 / 14 = $0.3214 (rounded to four decimal places)
For the 12-ounce drink:
Cost per ounce = $3.75 / 12 = $0.3125 (rounded to four decimal places)
Comparing the cost per ounce, the 12-ounce drink has a lower cost per ounce, making it the better deal.
So, the 12-ounce drink for $3.75 is the best deal.

Kris and Nathan put a down payment of 20% on the purchase of their house, and then financed
$150,000. What was the purchase price of the house
Answer: $187,500
Step-by-step explanation:
Let x = Purchasing price of house.
Given: Down payment = 20% of x
= 0.20x [20% = 0.20]
The amount financed = Purchasing price - Down payment
= x-0.20x
=(1-0.20)x
= 0.80x
As per given,
[tex]0.80x=150000\\\\\Rightarrow x=\dfrac{150000}{0.8}\\\\\Rightarrow\ x=\dfrac{1500000}{8}\\\\\Rightarrow\ x=187500[/tex]
Hence, the purchase price of the house =$187,500
