Lady_Fox [76]

Answer: -64\frac{2}{7}\text{ feet}

Step-by-step explanation:

When the scientists detect a signal frequency from the ocean floor, then the depth of submarine =-116\frac{2}{7} feet

=-\frac{814}{7} feet

When they dive farther to check the signal, then the depth of the submarine=-180\frac{4}{7}=-\frac{1264}{7} feet.

The net change in their elevation =-\frac{1264}{7}-(-\frac{814}{7})

=-\frac{1264}{7}+\frac{814}{7}\\=-\frac{450}{7}=-64\frac{2}{7}\text{ feet}

-4 x f (8) + 3 x g(-7) HELP ASAP
lubasha [3.4K]

Answer:

-32

Step-by-step explanation:

-4 + f(8) + 3 x g(-7) = ?

To find f(8), look at each of the f(x) function and find x = 8. The y value is the answer you will plug in for f(8). The same goes for g(-7), but you will be looking at the g(x) function at x = -7.

f(8) = -4

g(-7) = -8

Make sure you solve in the correct order using PEMDAS.

-4 + (-4) + 3 x (-8) = -32
