Answer:

x =  - 4.5 \\

Step-by-step explanation:

15(2 - x) = 13(3 - x) \\ 30 - 15x = 39 - 13x \\  - 15x + 13x =  - 30 + 39 \\  - 2x = 9 \\  \frac{ - 2x}{ - 2}  =  \frac{9}{ - 2}  \\ x =  - 4.5

hope this helps

brainliest appreciated

Answer:

-4.5

Step-by-step explanation:

15(2-x)=13(3-x)

Expand parentheses:

30-15x=39-13x

Add 15x to both sides:

30=2x+39

Subtract 39 from both sides:

2x=-9

Divide both sides by 2:

x=-4.5

Hope this helps!

Which rule represents the translation from the pre-image, ΔABC, to the image, ΔA'B'C'?
ANEK [815]
From the figure, it can be seen that the mage A'B'C' is obtained from the pre-image ABC by translating/shifting the vertices of the image by 7 units to the right and 6 units down.

Therefore, the rule represents the translation from the pre-image, ΔABC, to the image, ΔA'B'C' is <span>(x, y) → (x + 7, y – 6)</span>.
