Answer:

X=-7

Step-by-step explanation:

X + 142=135°

X=135-142

X=-7

So the value of X is -7

Answer:

Vertex is (-1/3, -13/3)

Axis of symmetry is x = -1/3

Step-by-step explanation:

For the vertex, you need to change it into vertex form which is y = a(x - h)^2 + k

Vertex form for this equation is:

Y = -6(x + 1/3)^3 - 13/3

To find the vertex, the formula is (h,k)

So, ( -1/3, -13/3)

Answer:

Dylan sold 48 bottles

Juan sold 32 bottles

Step-by-step explanation:

The ratio of bottles sold is;

J:D = 4:6

Dylan sold 16 more than Juan

That means d = j + 16

so;

j/j + 16 = 4/6

6j = 4(j + 16)

6j = 4j + 64

6j - 4j = 64

2j = 64

j = 64/2

j = 32

d = j + 16

d = 32 + 16

d = 48

Answer:

6c - 8d = 2 (3c - 4d)

Step-by-step explanation:

Factoring

To factor a polynomial, we must find the Greatest Common Divisor (GCD) among all its terms.

The expression to factor is 6c - 8d.

The GCD is found by factoring all terms:

6c : 2,3,c

8d : 2,2,2,d

And take the common divisor between the coefficients and the variables

GCD=2

Thus, the factorization is:

6c - 8d = 2 (3c - 4d)

Answer:

Approximately $2.232

Step-by-step explanation:

Given that:

Percentage increase in Price of chips = 12%

Approximate price of chips today = $2.50

Original price before the increase :

Let original price = y

(Original price) + (12% of original price) = approximate price today

y + (12% of y) = $2.50

y + 0.12y = 2.50

1.12y = 2.50

Divide both sides by 1.12

1.12y / 1.12 = 2.50 / 1.12

y = 2.2321428

y = $2.232

Hence, original price of chips is approximately $2.232

Responder:

y = 200x + 2000

Explicación paso a paso:

Deje que la ecuación lineal se exprese como y = mx + c

m es la pendiente

c es la intersección

Si la empresa produce $ 10 unidades, sus costos totales son $ 4000 dólares y si produce $ 15 unidades sus costos ascienden a $ 5000 dólares, entonces podemos representar esto como puntos de coordenadas;

(10,4000) y (15,5000)

Conseguir la pendiente

m = 5000-4000 / 15-10

m = 1000/5

m = 200

Obtener la intersección c

Sustituya m = 2000 y el punto (10, 4000) en la fórmula y = MX + c

4000 = 200 (10) + c

4000-2000 = c

c = 2000

Sustituya m = 200 y c = 2000 en la ecuación y = mx + c

y = 200x + 2000

Por tanto, la expresión lineal requerida es y = 200x + 2000

Answer:

51 were the total number of the tickets sold at a school carnival were early-admission tickets.

Step-by-step explanation:

Total number of tickets sold by  = 100

Let [tex]x[/tex] be the early-admission tickets sold by the school.

As 51% of the tickets sold at a school carnival were early-admission tickets.

so

[tex]x=\frac{51}{100}\times 100[/tex]

  [tex]= 51[/tex]

Therefore, 51 were the total number of the tickets sold at a school carnival were early-admission tickets.

Given :

Last year during the hurricane season the amount of rain that fell on the Texas gulf coast in October was 14 inches which was 3 1/2 times more than the rainfall during the month of September.

To Find :

Amount of rainfall in September.

Solution :

Let, amount of rainfall in September is x.

It is given that rainfall in October is 3 1/2 = 7/2 times of september.

So,

[tex]\dfrac{7}{2}x=14\\\\x = 4\ inches[/tex]

Therefore, rainfall in October is 4 inches.

Hence, this is the required solution.

Answer:

c. [tex] y + 2 = -3(x - 1) [/tex]

Step-by-step explanation:

By using a point on the line and the slope, we can determine the equation, in point-slope form, that is graphed in the figure.

Using two points, (1, -2) and (0, 1),

[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{1 -(-2)}{0 - 1} = \frac{3}{-1} = -3 [/tex]

m = -3

Using a point, (1, -2) and the slope (m), we can create an equation for the graph in point-slope form, by substituting x1 = 1, y1 = -2 and m = -3 in [tex] y - y_1 = m(x - x_1) [/tex].

Thus, we would have:

[tex] y -(-2) = -3(x - 1) [/tex]

[tex] y + 2 = -3(x - 1) [/tex]

The equation that is graphed in the figure is:

✔️[tex] y + 2 = -3(x - 1) [/tex]
