Answer:

The depth of the lake last year was 52 feet

Step-by-step explanation:

Given as :

This year depth of lake = 39 feet

Let the last year depth of lake = x feet

Now,

According to question :

The depth this year is 25% less than that of last year

I.e 39 feet = x - 25% of x

Or, 39 feet = \frac{75x}{100}

or, x =  \frac{3900}{75}

∴   x = 52 feet

Hence The depth of the lake last year was 52 feet   Answer

Find a a pair of numbers of both 4y-4x=48 and y= x-11
stich3 [128]

Answer:

There is no solution because the slopes of the line are the same.

Step-by-step explanation:

4y - 4x = 48

    + 4x    + 4x        Add 4x to both sides

4y = 4x + 48          Divide both sides by 4

y = x + 12

Now set both equations equal to each other since they equal y

x + 12 = x - 11

-x         - x           Subtract x from both sides

12 ≠ -11                No Solution

ABCD is a quadrilateral inscribed in a circle, as shown below:
malfutka [58]

Answer:

Option 4: <u>(2x + 16)° + (x)° = 180°</u>

Step-by-step explanation:

See the attached figure.

For a quadrilateral inscribed in a circle

The opposite angles are supplementary.

So, ∠D + ∠B = 180°

From the figure:

∠B = x°  and ∠D = (2x+16)°

∴  <u>(2x + 16)° + (x)° = 180°</u>

Help! This is so confusing please
Rus_ich [418]

Given equation is f(x)=6^x

Now it says to find f(2)

that simply means plug x=2 because we see that 2 is written in place of x in f(x) and f(2)

f(2)=6^2

f(2)=6*6

f(2)=36

Hence final answer is f(2)=36

You are looking for the shaded region that would be contained in both of the inequalities.

You have:
x+y \leq 805x+10y\ \textgreater \ 500

If you graph an shade the correct half-plane for those equations, you will see there is a triangular region on the left side of the first quadrant.
