Bailey & Riley sell magazines.
Solnce55 [7]

Answer:

10

Step-by-step explanation:

We can write Bailey's equation as:

29 + 1.50x

and Riley's equation as:

20 + 2x

Where

x is the number of magazines sold

Since Riley sold 12, her total pay for that day would be:

20 + 2x

20 + 2(12)

20 + 24

$44

Now, how many magazines Bailey need to sell? We equate Bailey's equation to 44 and find x:

29 + 1.5x = 44

1.5x = 44 - 29

1.5x = 15

x = 15/1.5

x = 10

hence, Bailey need to sell 10 magazines to make same money as Riley

If h(x) = (f o g)(x) and h(x) = sqrt(x+5), find g(x) if f(x) = sqrt(x+2)
agasfer [191]

Answer:

  • g(x) = x + 3

Step-by-step explanation:

<h3>Given</h3>
  • h(x) = (f ο g)(x)
  • h(x) = \sqrt{x+5}
  • f(x) = \sqrt{x+2}
<h3>To find</h3>
  • g(x)
<h3>Solution</h3>

<u>We know that:</u>

  • (f ο g)(x) = f(g(x))

<u>Substitute x with g(x) and solve for g(x):</u>

  • \sqrt{x+5} = \sqrt{g(x)+2}
  • x + 5 = g(x) + 2
  • x + 3 = g(x)
  • g(x) = x + 3

-4x - 2 = -18 POR FA AYUDENME
charle [14.2K]

Answer:

The answer is x=4

Step-by-step explanation:

so you have -4x-2=-18

so we get rid of -2 by adding it to the other side so you'll end up having -4x=-16

you then divide that by -4 on both sides and get x=4 as your remaining answer
