. If the puppies are 36% of the total dog and cat population, how many dogs and cats are in the animal shelter?
Answer:
Total number of cat and dogs = 32
Step-by-step explanation:
Missing:
Total number of puppies = 18
Puppies percent = 36%
Find:
Total number of cat and dogs
Computation:
Total number of Animals = 18 (100/36)
Total number of Animals = 50
Total number of cat and dogs = Total number of Animal - Total number of puppies
Total number of cat and dogs = 50 - 18
Total number of cat and dogs = 32

I'm not sure how to factor this
Y = -5 (x + 2)^2 - 10
Convert the equation from vertex form to standard form.
Given:
The vertex form of a quadratic equation is
[tex]y=-5(x+2)^2-10[/tex]
To find:
The standard form of the given quadratic equation.
Solution:
We have,
[tex]y=-5(x+2)^2-10[/tex]
Using the formula [tex](a+b)^2=a^2+2ab+b^2[/tex], we get
[tex]y=-5(x^2+2(x)(2)+(2)^2)-10[/tex]
[tex]y=-5(x^2+4x+4)-10[/tex]
Using distributive property, we get
[tex]y=-5x^2-20x-20-10[/tex]
[tex]y=-5x^2-20x-30[/tex]
Therefore, the standard form of the given equation is [tex]y=-5x^2-20x-30[/tex].

Answer:
a) x = 10
b) DA = 24
c) perimeter = 110
Step-by-step explanation:
a) Since it's a parallelogram, the opposite sides are of equal length. This means that line DC = AB, so u can substitute in the values and solve for x:
DC = AB
5x - 18 = 2x + 12 (move terms so that like terms are on the same side)
5x - 2x = 12 + 18 (simplify like terms)
3x = 30 (divide by 3 on both sides to isolate the x)
x = 10
b) now that u know the value of x, you can use it to find the length of DA. again, opposite sides are equal, so DA = BC, which means DA = 3x - 6. substitute in your known value of x and solve:
3x - 6
= 3(10) - 6
= 30 - 6
= 24
Therefore, the length of DA - 24
c) Since u know the length of DA (and therefore BC), u just have to find the length of either DC or AB and then multiply that by 2 and add it.
First, substitute in the value of x for either DC or AB (i'm gonna use AB)
2x + 12
= 2(10) + 12
= 20+12
= 32
now, to find the perimeter use this formula: 2(AB) + 2(DA)
this equals to 2(32) + 2(24) = 64+46 = 110
and that's the perimeter!

Answer:
y=-x+11
Step-by-step explanation:
Kids filled up a swimming pool with 5000 gallons of water. The water leaked out at 2 gallons per minute. Write a linear equation to model this situation.
Answer:
Y= -2x + 5000
Step-by-step explanation:
The linear equation which model the situation is y = 5000 - 2x
Given:
Total quantity of water in the swimming pool = 5000 gallonsLeakage per minute = 2 gallonsNumber of minutes = xTotal water remaining in the pool = yThe equationTotal water remaining in the pool = Total quantity of water in the swimming pool - (Leakage per minute × Number of minutes)
y = 5000 - (2 × x)
y = 5000 - 2x
Therefore, the linear equation which model the situation is y = 5000 - 2x

In what ways are linear functions and exponential functions the same? In what ways are they different? How can they be used to model real world situations?
Answer:
In linear functions, rate of change is constant: as x goes up, y will go up a consistent amount. In exponential functions, the rate of change increases by a consistent multiplier- it will never be the same but there will be a pattern. Exponential functions are used in real world situations such as bacterial growth/decay, population growth/decline, and compound interest. Linear functions/equations can be used for comparing rates of pay. Hope this helped!
