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].
Btw there is 2 more options. number 3 is, (step3) and number 4 is, Raul did not make a mistake.
I'm not sure how to factor this
-24 1/2 as a decimal number
Answer and Explanation
__________________________________________________________
-24.5__________________________________________________________
The answer is -24.5 because...
[tex]\frac{1}{2}[/tex] = [tex]0.5[/tex]
and
[tex]-24[/tex] = [tex]-24[/tex]
__________________________________________________________
[tex]-24[/tex] [tex]+[/tex] [tex]0.5[/tex] = -24.5

. 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

Someone please help!!! It’s timed!
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!
hope this helps!
