Solve 2x + 20 = 6x – 12*

Answers

Answer:

x = 8

Step-by-step explanation:

Given

2x + 20 = 6x - 12 ( subtract 2x from both sides )

20 = 4x - 12 ( add 12 to both sides )

32 = 4x ( divide both sides by 4 )

8 = x

=> 2x + 20 = 6x - 12

=> 20 + 12 = 6x - 2x

=> 32 = 4x

=> x =32/4

=> x = 8

f(x)= 2x +6 , vertical shrink by a factor of 1/2

Answers

Answer:

g(x) = x+3.

Step-by-step explanation:

i hope this helps :D

When a function is shrunk vertically, the function has undergone a form of transformation.

The resulting function when [tex]f(x) = 2x + 6[/tex] vertically shrink by 1/2 is [tex]f'(x) = x + 3[/tex]

Given that:

[tex]f(x) = 2x + 6[/tex]

[tex]k = \frac 12[/tex] --- shrink factor

When a function is shrunk vertically, the rule of transformation is:

[tex](x,y) \to (x,ky)[/tex]

So, we have:

[tex]f'(x) = k f(x)[/tex]

The new function becomes

[tex]f'(x) = \frac 12 \times (2x + 6)[/tex]

[tex]f'(x) = x + 3[/tex]

Hence, when [tex]f(x) = 2x + 6[/tex] is vertically shrunk by 1/2, the new function is [tex]f'(x) = x + 3[/tex]

0.2(3k+1)=-0.4-(-0.2-0.1K)

Answers

Answer:

k=−0.8

Step-by-step explanation:

Start with the equation: 0.2(3k+1)=-0.4-(-0.2-0.1K)

Use distributive property on each side of the equation. For the left side, distribute 0.2 into 3k and 1, and for the right side, distribute -1 into -0.2 and -0.1k. (We use a -1 because the negative sign on the outside of the parenthesis is equivalent to -1)

(0.2)(3k) + (0.2)(1) = 0.6k + 0.2

(-1)(-0.2) + (-1)(-0.1k) = 0.2 + 0.1k

New equation: 0.6k + 0.2 = -0.4 + 0.2 + 0.1k

Now we can combine like terms on the right side. (-0.4 and 0.2)

0.6k + 0.2 = 0.1k - 0.2

Now to get rid of k on one side, we can subtract 0.1k from the right side.

(0.6k - 0.1k) + 0.2 = (0.1k - 0.1k) - 0.2

0.5k + 0.2 = -0.2

Now we need to get 0.5k by itself, so we'll subtract the 0.2 on both sides.

0.5k + (0.2 - 0.2) = (-0.2 - 0.2)

0.5k = -0.4

To get k by itself, we must divide both sides by 0.5.

(0.5k / 0.5) = (-0.4 / 0.5)

k = -0.8

find an expression for the nth term -3 , 2 , 7, 12

Answers

Answer:

5n-8

Step-by-step explanation:

Because this is an arithmetic progression, there is simply an addend that is being added to every number. Because that is 5, the expression, for now, would be 5n. However, the progression does not start at 0, so we will have to subtract 3, and then it would be 5n - 3. We're still not at the answer; this is because the first term starts at 1, not 0. We will have to account for that, so subtract the coefficient, or 5, from the whole expression. That would be 5n - 8, and that would be the answer.

Which expression is always an integer value?

When two integers are multiplied, the result is always an integer.

In this problem, expression H has the multiplication of two integers, 9 and -3, hence option B is correct.

The other expressions have rationals involved in the multiplication, hence the result of the expression will be a rational.
