Answer:
Its B (3,-4)
When rotating at point 180 degrees the equation for that is (-x,-y) so in this case (-3,4)
3 turns into a positive because two negatives equal a positive
and 4 turns into a negative

hello! i'd like someone to help me convert this problem to an equation, please !! i don't need the result :(
Tomorrow Andrea is on her birthday and her best friends do not know how old Andrea is. When they ask Andrea how old she is, she gets angry and says "In 11 more years my age will be half the square of my age 13 years ago". Andrea's friends are not very good at math. Help them and tell them what Andrea's age is. (You must send development of this exercise)
Answer:
21
Step-by-step explanation:
We can set Andrea's current age as x.
In 11 years, her age will be half the square of her age 13 years ago. We get the equation:
[tex]x+11=\frac{(x-13)^2}{2} \\2(x+11)=(x-13)^2\\2x+22=x^2-26x+169\\x^2-28x+147=0\\(x-21)(x-7)=0\\x=21, x=7[/tex]
Ok, now we know that Andreas age could be either 21 or 7. However, the problem states that "in 11 more years my age will be hald the square of my age 13 years ago." It would not make sense for Andrea to be currently 7 if she was not yet born 13 years ago.
Therefore, Andrea's age is 21.
I hope this helps! Let me know if you have any questions :)
Which expression is equivalent to 16 - 4x^2?
Answer:
4(2 - x)(2 + x)
Step-by-step explanation:
16 - 4x² ← factor out 4 from each term
= 4(4 - x²) ← difference of 2 squares
= 4(2 - x)(2 + x) ← in factored form

Polynomial is an expression that consists of indeterminates(variable) and coefficients. The correct option is A.
What are polynomials?Polynomial is an expression that consists of indeterminates(variable) and coefficient, it involves mathematical operations such as addition, subtraction, multiplication, etc, and non-negative integer exponentials.
For the given expression x³ – 7x² – 5x + 35 the factorisation by grouping can be done as,
x³ – 7x² – 5x + 35
Take x² as common from the first two terms, while -5 as common from the last two terms,
= x²(x – 7) –5(x – 7)
Take (x–7) as the common term from the two terms,
= (x² – 5)(x – 7)
Hence, the correct option is A.

can someone help me identify c(6)=
Answer and Step-by-step explanation:
To solve, simply plug 6 in for m in the equation.
C(6) = 50(6) + 79.50
6 times 50 is 300.
300 + 79.50 = 379.50 = C(6)
The answer is 379.5
(Looking at the question again, I don't think what I said is what it is asking for, soo)
The slope of the function given represents the amount that needs to be paid every month. The y-intercept (79.50) represents the initial cost (starting amount) for paying the membership.

En el cumpleaños de Manolito se inflaron 144 globos. Los 2/9 de los globos eran rojos; los 5/18, verdes y 1/6 eran amarillos. ¿Cuántos globos eran de otros colores?
Answer:
48 globos
Step-by-step explanation:
De la pregunta anterior, se nos dice que:
En el cumpleaños de Manolito se inflaron 144 globos.
Por eso:
Para globos rojos
2/9 de los globos eran rojos
Número de globos rojos = 2/9 × 144 globos
= 32 globos
Para globos verdes
5/18 eran verdes
Número de globos verdes = 5/18 × 144 globos
= 40 globos
Para globos amarillos
1/6 eran amarillas
Número de globos amarillos = 1/6 × 144 globos
= 24 globos
Tenga en cuenta que:
Número total de globos =
Globos rojos + Globos verdes + Globos amarillos + Otros colores
Otros colores = 144 globos - (globos rojos + globos verdes + globos amarillos)
Otros colores = 144 globos - (32 + 40 + 24) globos
= 144 globos - 96 globos
= 48 globos
Por lo tanto, la cantidad de globos que son de otros colores = 48 globos
A basketball free throw can be modeled by a parabolic path, which can be represented by the function b(x) = - 0.25 x^2 + 4x, where x is time, in seconds, and b(x) is the height of the ball off the ground in feet.
What is the VERTEX and what do the coordinates mean in the context of the problem?
please solve algebraically
Answer:
The vertex of this problem is (8,16). This means that the highest height the ball reaches is at t = 8s, and this maximum height is of 16 feet.
Step-by-step explanation:
Vertex of a quadratic function:
Suppose we have a quadratic function in the following format:
[tex]f(x) = ax^{2} + bx + c[/tex]
It's vertex is the point [tex](x_{v}, y_{v})[/tex]
In which
[tex]x_{v} = -\frac{b}{2a}[/tex]
[tex]y_{v} = -\frac{\Delta}{4a}[/tex]
Where
[tex]\Delta = b^2-4ac[/tex]
If a<0, the vertex is a maximum point, that is, the maximum value happens at [tex]x_{v}[/tex], and it's value is [tex]y_{v}[/tex].
b(x) = - 0.25 x^2 + 4x
Quadratic equation with [tex]a = -0.25, b = 4[/tex].
Vertex:
[tex]x_{v} = -\frac{4}{2(-0.25)} = 8[/tex]
[tex]\Delta = 4^2-4(-0.25)(0) = 16[/tex]
[tex]y_{v} = -\frac{16}{4(-0.25)} = 16[/tex]
The vertex of this problem is (8,16). This means that the highest height the ball reaches is at t = 8s, and this maximum height is of 16 feet.

What's the area of this
Answer:
133
Step-by-step explanation:
Because the figure is an irregular figure we need to break it up into two regular figures
The figure would be broken into..
A square with a side length of 4
And a rectangle with a length 13 and a width of 9
We now find the areas of the regular figures and add them together to get our answer
For the square.
To find the area of a square simply square the side length
Area = 4^2 = 16
For the rectangle
to find the area of the rectangle simply multiply the Length by the width
Area = 13*9= 117
Finally add the two areas together to get the area of the composite figure
117 + 16 = 133

Solve the equation to find where the treste ground levelEnter your answers from least to greatest and round to the nearest The meets the ground at and
Answer:
The trestle meets ground level at 0.875 units and 9.125 units
Step-by-step explanation:
Poorly formatted question.
The given equation is:
[tex]y = -x^2 + 10x - 8[/tex]
Required
The point where the trestle gets to the ground level
To do this, we set [tex]y = 0[/tex]
So, we have:
[tex]-x^2 + 10x - 8 = 0[/tex]
Multiply through by -1
[tex]x^2 -10x + 8 = 0[/tex]
Solve using quadratic formula:
[tex]x= \frac{-b \± \sqrt{b^2 - 4ac}}{2a}[/tex]
Where:
[tex]a = 1; b =-10; c = 8[/tex]
So, we have:
[tex]x= \frac{-(-10) \± \sqrt{(-10)^2 - 4*1*8}}{2*1}[/tex]
[tex]x= \frac{-(-10) \± \sqrt{68}}{2*1}[/tex]
[tex]x= \frac{-(-10) \± 8.25}{2}[/tex]
[tex]x= \frac{10 \± 8.25}{2}[/tex]
Solve the fraction
[tex]x= 5 \± 4.125[/tex]
Split
[tex]x= 5 + 4.125\ or\ x= 5 - 4.125[/tex]
[tex]x= 9.125\ or\ x= 0.875[/tex]

Kendra spent ⅓ of her allowance on a book and ⅖ on a snack. If she had four dollars remaining after purchasing a book and snack, what was the total amount of her allowance?
Answer: 15$
Step-by-step explanation:
Given
Kendra spent one-third of allowance on a book and two-fifth on snack.
If she had four dollar remaining after purchase
Suppose x is the original amount
[tex]\therefore x-\dfrac{x}{3}-\dfrac{2x}{5}=4\\\\\Rightarrow \dfrac{15x-5x-6x}{15}=4\\\\\Rightarrow 4x=60\\\Rightarrow x=15[/tex]
Thus, 15$ was her total allowance.

3) Aaron and his friend Bobby went school shopping and bought pens &
pencils. Each pen costs $3 and each pencil costs $2. They bought a total
of 7 items for $18. How many pens did they buy?
Answer:
3 pens.
Step-by-step explanation:
x+y=7 where x is # of pens and y =# of pencils
3x + 2y= $18
from first equation, x=-y+7 so substitute that into other equation
3(-y+7)+2y=18
-3y+21+2y=18
-y=18-21
-y=-3
y=3
now replace y =3 into first equation
x+3=7
x=4
