Evgen [1.6K]

Step-by-step explanation:

1.

  • (48 - 12.80)/2 = $17.6

2.

  • 250/6 ≈ 42 and more

3.

  • 485 - 319 = 166 more people

4.

  • 14.5x + 80 > 500
  • 14.5x > 420
  • x > 420/14.5
  • x > 29

5.

  • 1.25x + 3 ≤ 28
  • 1.25x ≤ 25
  • x ≤ 25/1.25
  • x ≤ 20 miles

6.  <em>This seems a typo... 460 is likely $60</em>

  • 60x + 145 ≤ 625
  • 60x ≤ 625 - 145
  • 60x ≤ 480
  • x ≤ 480/60
  • x ≤ 8 days

If f(x) and r1(x) are inverse functions of each other and f(x)=2x+5 , what is f^-1(8) ?
GenaCL600 [577]

Answer:

3/2

Step-by-step explanation:

Given y = 2x + 5, let's rewrite the equation in terms of x;

y = 2x + 5 => Bring 5 to the other side

2x = y - 5 => Divide either side by 2

x = (y - 5)/2

If we want to take the inverse, simply swap the variable's positions...

We have y = (x - 5)/2

Now let's determine f^-1(8), substituting for "y" provided y is our inverse, f^-1

f^-1(8) = (8 - 5)/2 = 3/2

Solution: 3/2

BRAINLEYEST PLEASE HELP
sdas [7]

1) Between the pentagons, you take the small number over big number, so 6:14. But we can simplify that more all the way down to <em>3:7</em>

<em />

2) Between the squares, we can do the same thing.... <em>3:5</em>

<em></em>

3) Between the parallelograms, it would be <em>2:5</em>

<em></em>

4) Between the hexagons, it would be 4:12, but when we simplify, it becomes <em>1:3</em>
