Answer:

x = 5/6.

Step-by-step explanation:

8^2x = 32

(2^3)^2x = 2^5

2^(6x) = 2^5

6x = 5

x = 5/6.

The error in the process is we have to add the coordinates john subtracts the coordinates.

The transformation coordinates are (8, 12).

Given that

John says the transformation rule (x, y) Right-arrow (x 4, y 7) can be used to describe the slide of the pre-image (4, 5) to the image (0, –2).

We have to determine

What was his error?

According to the question

A preimage or an inverse image is the 2D shape that we used to denote before any transformation.

Image is the figure that we get after transformation.

The coordinates of preimages are (4, 5).

Then,

After transformation the co-ordinates are as follows;

$(4+4, \ 5+7)\\\\(8,12)$

Hence, the transformation coordinates are (8, 12).

Plz help me with b,a , and b

solniwko [45]

2A) C is correct.

2B) If x + 13 = 28, solve.
$x+13=28\\
x=15$
If x = 15 and x + 13 = 28, you can solve it two ways:
1. Plug x into 4x + 26 to get a perimeter of 86, or
2. Redo the equation:
$P=2(15)+2(28)\\
P = 30+56\\
P=86$

3a. Since the 6z is negative, you want an expression the has 5z - (11z). Answers A and D have that in their answer.
But since the 13 is positive, you want the answer that subtracts the smaller number from the larger. Thus, D is your answer since it subtracts 2 from 15.

3b) You think about this question the same way; 6z is positive, so the smaller number is being subtracted from the larger, meaning that 11z - 5z is what you look for. C and D are the two that have that, so now let's look at the second term.
The 13 is negative, so you want the answer that has 2 - 15. The answer that has that is D.

Hope this helps :D

F(x)=2x+3 and g(x)=4x-2. Find f(x) x g(x). Find f(x) - g(x).

const2013 [10]

Answer:

f(x) * g(x) is 8x^2 + 8x -6

f(x) - g(x) is -2x + 5

Step-by-step explanation:

When finding the answer, we can notice they already give the values for the needed answers.

The first one requires f(x) and g(x). At the beginning of the question it shows that f(x) is equal to 2x+3. Meaning we can plug in 2x+3 for f(x).

The same goes for g(x). At the begginning of the question, it shows that g(x) is equal to 4x-2. Meaning we can plug in 4x-2 for g(x).

f(x) * g(x)

(2x+3) * (4x-2)

To find the answer, we need to distibute the 2x+3 into 4x-2.

To distribute, we do :

2x * (4x-2) + 3 * (4x-2)

First we distribute the 2x

2x * 4x = 8x^2 and 2x * -2 = -4x

8x^2 - 4x

Next we distibute the 3

3 * 4x = 12x and 3 * -2 = -6

12x - 6

Now we can combine them by adding like terms to get the asnwer:

8x^2 = 8x^2

-4x + 12x = 8x

-6 = -6

The first answer is 8x^2 + 8x -6

Second question:

Since we already know the values for f(x) and g(x), all we have to do is plug in the values.

(2x+3) - (4x-2)

This time, since we are subtracting, all we have to do is subtract like terms.

2x - 4x = -2x

3 - (-2) = 5

The second answer is -2x + 5
