Answer:

x = 16

Step-by-step explanation:

$\frac{2x - 5}{x + 8} = \frac{22.5}{20}$

Cross multiply

$(2x - 5)*20 = (x + 8)*22.5$

$40x - 100 = 22.5x + 180$

Collect like terms

40x - 22.5x = 100 + 180

17.5x = 280

Divide both sides by 17.5

x = 280/17.5

x = 16

Owen is fishing from a dock he starts with the bait 2 feet below the surface he reels out the boat 19 feet then reels it back in

Hatshy [7]

Answer:

The bait is 14 feet below the water surface

Step-by-step explanation:

Here, we want to know the final position of the bait relative to the surface of the water.

Firstly, he starts with the bait at 2 feet below the water surface. The reels out the bait a further 19 feet, the new position of the bait relative to the water surface will be 2 + 19 = 21 feet

Now, he reels the bait back by 7 feet.

Thus, the new depth of the bait relative to the water surface will be 21-7 = 14 feet

What is the transformation of the logarithmic function from the parent log5 x?

TiliK225 [7]

Answer: Choice #3 - compressed horizontally and translated by 4 units to the right.

$g(x)=\log_5(4x-16)=\log_5 4(x-4)$

This corresponds to horizontal shift to the right by 4 units and a horizontal compression.
