Answer:
Vertex: (-1, 4)
Maximum: f(-1) = 4
Increasing: (-∞, -1)
Decreasing: (-1, ∞)
Step-by-step explanation:
The equation can be written in vertex form by "completing the square."
First factor out the leading coefficient from the x-terms.
f(x) = -(x² +2x) +3
Then add the square of half the x-coefficient inside parentheses. Add the opposite of that amount outside parentheses.
f(x) = -(x² +2x +1) +3 +1
Write in vertex form.
f(x) = -(x +1)² +4 . . . . . . . compare to a(x -h)² +k
You can see that the vertex is (h, k) = (-1, 4), and that the vertical scale factor 'a' is negative. This means the vertex is the maximum and the parabola opens downward.
The function will be increasing to the left of the maximum, decreasing to its right.

Answer:
slope: 45y-intercept: 30equation: y = 45x + 30Step-by-step explanation:
The slope is the cost per month. (A slope is often expressed as a ratio: dollars per month, in this case.) The slope is 45.
The y-intercept is the value that obtains when the number of months (in this case) is zero. It is the activation fee, 30. The y-intercept is 30.
__
The equation in slope-intercept form is ...
y = mx + b . . . . . where m is the slope and b is the y-intercept
Using the above numbers, the equation is ...
y = 45x + 30
Factor the trinomial 3x2 + 13x − 10 by grouping.
Answer:
(3x - 2) (x+5)
Step-by-step explanation:
3x^2 + 13 - 10
15× - 2 = -30
15+-2 = 13.....substitute 15x - 2x in place of 13x
3x^2+15x-2x-10
Factorise the first two values, thrn the second two
3x (x+5) - 2 (x+5)
Gathering the like terms together you eill be left with the following
(3x - 2) (x+5)
The factors of the trinomial 3x² + 13x - 10 is (3x-2)(x+5).
What is Factorization?The breaking or decomposition of an entity (such as a number, a matrix, or a polynomial) into a product of another entity, or factors, whose multiplication results in the original number, matrix, etc., is known as factorization or factoring in mathematics.
we have,
Trinomial= 3x² + 13x - 10
Now, factories using splitting the middle term we get
3x² + 13x - 10
= 3x² + 15x - 2x - 10
= 3x( x +5) - 2(x+ 5)
= (3x - 2) (x+ 5)
So, the factors are (3x- 2(x+5)

Can someone help with this math problem? 3 (x+6) = 27
Answer:
x = 3
Step-by-step explanation:
Use distributive property: a(b +c) =(a*b) + (a*c)
3(x + 6) = 27
3*x + 3*6 = 27
3x + 18 = 27 {Subtract 18 from both sides}
3x + 18 -18 = 27 - 18
3x = 9 {Divide both sides by 3}
3x/3 = 9/3
x = 3

A partir del 1.° de diciembre, un camión de helados visita la calle de Sara cada 3 días y la calle de Ema cada 5 días. ¿Cuáles son los primeros 2 días que el camión visita ambas calles el mismo día?
Answer:
Los primeros 2 días que el camión visita ambas calles el mismo día es el 15 y 30 de diciembre.
Step-by-step explanation:
Los múltiplos de un número son todos los posibles resultados de multiplicar ese número por todos y cada uno de los números naturales.
Es decir, los múltiplos de un número natural son los números naturales que resultan de multiplicar ese número por otros números naturales.
El conjunto de los múltiplos de un número determinado (salvo el cero) es infinito, pues existen infinitos naturales para multiplicar.
Para determinar cuáles son los primeros 2 días que el camión visita ambas calles el mismo día, debes encontrar los múltiplos de 3 y 5:
múltiplos de 3: 3; 6; 9; 12; 15; 18; 21; 24; 27; 30
múltiplos de 5: 5; 10; 15; 20; 25; 30; 35; 40; 45; 50
Podes observar que los 2 primeros números comunes o que coinciden entre los múltiplos de 3 y 5 son 15 y 30. Esto quiere decir que los primeros 2 días que el camión visita ambas calles el mismo día es el 15 y 30 de diciembre.

The First equation and the Third Equation
are equivalent to 6x - 24.
1) 6 ( x - 4 )
3)3 ( 2x - 8 )
Answer:
first one and third one. hope u get it right!
Step-by-step explanation:
6(x-4)
distribute (6*x and 6*4) then it equals 6x - 24
2(3x - 24) = 6x - 48
3(2x - 8) = 6x - 24
3(3x - 21) = 9x - 63
7. The daily cost of production in a video game factory is calculated using c(x) = 400 + 25x, where x is
the number of complete video games manufactured. Which set of numbers best defines the domain of c(x)?
(1) integers
(2)positive real numbers
(3) positive rational numbers
(4)whole numbers
Answer:
(4) whole numbersStep-by-step explanation:
Given function:
c(x) = 400 + 25xwhere x is the number of complete video games.The complete video games can be expressed as positive integers or whole numbers, so the domain is whole numbers.
Correct choice is (4)
Answer:
Whole Number
Explanation:
Domain : The set of all the input values (i.e. the value of x ) in the function is called domain
The daily cost of production in a video game factory is calculated using c(x) = 400 + 25x
Cost expression : C(x) = 400 + 25x
Cost expression : C(x) = 400 + 25x
As x defines the number of complete video, since number of video cannot be negative.
1) Integers : integers are the numbers which can be positive, negative or zero, but cannot be a fraction
As, number of videos cannot be negative
so, x cannot be any integers
So, Integers is not the domain
2) Positive real numbers : Real numbers are the numbers which include both rational and irrational numbers.
As the x represent the complete number of video games, thus, x cannot be irrational
Hence, Positive real numbers is not the domain
3) Positive Rational Number : a number is expressed in the form of p/q then it is a rational number
The number of videos are in the complete number, so a fraction cannot be a complete number, thus, rational number cannot be a domain.
4) Whole Number : Whole numbers include natural numbers that begin from 1 onwards
As Numbers of videos are the complete number, and they are always positive, which is the defination of whole number, Domain is whole number

A small plant manufactures riding lawn mowers. The plant has fixed costs of GHC48,000 per day and a variable cost of GHC1,400 per unit produced. The mowers are sold for GHC1,800 each. The cost and revenue functions are in that order and , where is the total number of mowers produced and sold each day. How many units must be manufactured and sold each day for the company to break even?
Answer:
120
Step-by-step explanation:
The break-even point is the point where revenue =cost
48,000+ 1400x = 1800x
48000=400x
X=48000/400
X=120
Equilibrium quantity is 120 mowers
