Answer:

x=10/3

Step-by-step explanation:

8x-2-5x=8

then you group like terms=

8x-5x-2=8

add similar elements

3x-2=8

Add 2 to both sides

3x-2+2=8+2

Then lastly divide both sides by 3

3x/3=10/3

And you get 10/3

What is the surface area of this point

Kaylis [27]

Answer:

The answer is 30ft.

Step-by-step explanation:

To find the surface area of a rectangle, we use the formula L(2) + W(2) + H(2)

Our length is 7ft

Our Width 2ft

Our height is 6ft

Let's plug our numbers into our equation:

7(2) + 2(2) +6(2)

= 14 + 4 + 12

=30 ft.

Actividad 1.1 Investigue sobre el tema de diferenciabilidad en un punto para encontrar los valores de "a" y "b" tales

Olegator [25]

Answer:

a = 8

b = -8

Step-by-step explanation:

You have the following function:

$f(x)\\\\=at+b;\ \ t$

A function is differentiable at a point c, if the derivative of the function in such a point exists. That is, f'(c) exists.

In this case, you need that the function is differentiable for t=2, then, you have:

$f'(t)=a;\ \ \ \ t$

If the derivative exists for t=2, it is necessary that the previous derivatives are equal:

$f'(2)=a=4(2)\\\\a=8$

Furthermore it is necessary that for t=2, both parts of the function are equal:

$8(2)+b=2(2)^2-1\\\\16+b=8-1\\\\b=-8$

Then, a = 8, b = -8
