If 6x - 9 = x, what is the value of x ?
Tju [1.3M]

Answer:

x = 9/5

Step-by-step explanation:

We want to combine like terms and isolate the variable (x) from the constants (regular numbers).

Subtract x from both sides:

6x-9-x=x-x ⇒ 5x-9=0

Now add 9 to both sides:

5x-9+9=0+9 ⇒ 5x=9

Divide by 5 from both sides:

5x/5=9/5 ⇒ x=9/5

Thus, the answer is x = 9/5.

Hope this helps!

Please help will mark brainliest<br> one half * 2 * 25
Artist 52 [7]
"one half" = \frac{1}{2}
Your problem becomes  this but you don't have to do this method to solve this problem: \frac{1}{2} * \frac{2}{1} * \frac{25}{1}. So,
\frac{1}{2} ( \frac{2}{1} ) ( \frac{25}{1} )  \\  \frac{1}{2}  ( \frac{2}{1} )  = 1  \\  \frac{1}{1} ( \frac{25}{1} ) =  \frac{25}{1}   \\ Answer: 25

What are the coordinates of the image produced by applying the composition ry o T0-3 to the point (3, 5)? A. (–3, 2) B. (–3, 8)
Gennadij [26K]

Answer:

C. (3,6)

explenation

We are given that,

The point (-3,-6) is transformed by the rule .

That is, the point is reflected across y-axis and then reflected across x-axis.

That is, the rule for the transformation is (x,y) → (-x,y) → (-x,-y).

So, we get,

(-3,-6) → (3,-6) → (3,6)

Thus, the co-ordinates of the image are (3,6).

So, option C is correct.
