Lorenzo tiene 4 cajas de huevo, cada uno con 50 huevos y 3 cartones del mismo producto con 10 de ellos ¿Cuántos huevos hay en total?

Answers

Responder:

240 huevos

Explicación paso a paso:

Número de cajas de huevos = 4

Huevos por caja = 50

Total de huevos en caja = 50 * 4 = 200 huevos

Número de cajas = 3

Número de huevos por caja = 10

Total de huevos en caja = 10 * 4 = 40 huevos

Huevos totales = (huevos en caja + huevos en cartón)

Total = (200 + 40) = 240 huevos

The area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

Here b = 17 and h = 4 , then

Evaluate the function when x=−2, 0, and 5.

g(x)=3x−2


g(−2)=

g(0)=

g(5)=


I'm very confused, please help!

Answers

g(x) = 3x-2
g(-2) = 3(-2) - 2
g(-2) = -6-2
g(-2) = -8

g(0) = 3(0)-2
g(0) = 0-2
g(0) = -2

g(5) = 3(5)-2
g(5) = 15-2
g(5) = 13

Answer:

Step-by-step explanation:

g(x)=3x−2

g(−2)= 3(-2) - 2 (after substituting -2 for x):  g(-2) = -6 - 2 = -8

g(0)=  3(0) - 2 = -2

g(5)=  3(5) - 2 = 13

Answer:

[tex]a = -2[/tex]

Step-by-step explanation:

Given

The attached function (graph)

Required

Find a

The given function is quadratic and will be solved using:

[tex]y = ax^2 + bx + c[/tex]

From the attachment:

[tex](x,y) = (-3,4)[/tex]

[tex](x,y) = (-2,2)[/tex]

[tex](x,y) = (-4,2)[/tex]

Substitute these values in [tex]y = ax^2 + bx + c[/tex]

For: [tex](x,y) = (-3,4)[/tex]

[tex]4 = a(-3)^2 + b(-3) + c[/tex]

[tex]4 = 9a -3b + c[/tex]

For: [tex](x,y) = (-2,2)[/tex]

[tex]2 = a(-2)^2 + b(-2) + c[/tex]

[tex]2 = 4a -2b + c[/tex]

For: [tex](x,y) = (-4,2)[/tex]

[tex]2 = a(-4)^2 + b(-4) + c[/tex]

[tex]2 = 16a -4b + c[/tex]

So, we have:

[tex]4 = 9a -3b + c[/tex] --- (1)

[tex]2 = 4a -2b + c[/tex] ---- (2)

[tex]2 = 16a -4b + c[/tex] --- (3)

Make c the subject in (1)

[tex]c = 4 - 9a + 3b[/tex]

Substitute [tex]c = 4 - 9a + 3b[/tex] in (2) and (3)

[tex]2 = 4a -2b + c[/tex]

[tex]2 = 4a -2b + 4 - 9a + 3b[/tex]

Collect Like Terms

[tex]-4 + 2 = 4a - 9a-2b + 3b[/tex]

[tex]-2 = - 5a+b[/tex] --- (4)

[tex]2 = 16a -4b + c[/tex]

[tex]2 = 16a - 4b + 4 - 9a + 3b[/tex]

Collect Like Terms

[tex]2 -4 = 16a - 9a + 3b- 4b[/tex]

[tex]-2 = 7a -b[/tex] --- (5)

Add 4 and 5

[tex]-2 = - 5a+b[/tex]

[tex]-2 = 7a -b[/tex]

--------------------------

[tex]-2 - 2 = -5a + 7a +b - b[/tex]

[tex]-4 = 2a[/tex]

Divide through by 2

[tex]-2 = a[/tex]

[tex]a = -2[/tex]
