Answer:

Answer is (f - g)(x)  = -7x - 3

Step-by-step explanation:

We have:

f(x) = -3x - 5

g(x) = 4x -2

We need to find: (f - g)(x)

So, we can write:

(f - g)(x) = f(x) - g(x)

           = (-3x -5) - (4x - 2)

           = -3x - 5 -4x + 2

           = - 3x - 4x -5 +2

  (f - g)(x)  = -7x - 3

So we get  (f - g)(x)  = -7x - 3

A bag contains counters that are red, black , or green . 1/3 of the counters are red 1/6 of the counters are black There are 15
Nadya [2.5K]

Answer:

There are 5 black counters in the bag.

Step-by-step explanation:

15 green counters in the bag

The proportion of green counters is given by:

p = 1 - (\frac{1}{3} + \frac{1}{6}) = 1 - (\frac{2}{6}+\frac{1}{6}) = 1 - \frac{3}{6} = 1 - \frac{1}{2} = \frac{2}{2} - \frac{1}{2} = \frac{1}{2}

So, we have that, the total is x. So

\frac{x}{2} = 15

x = 30

There are 30 total counters.

How many black counters are in the bag ?

A sixth of the counters are black. So

\frac{1}{6} \times 30 = \frac{30}{6} = 5

There are 5 black counters in the bag.

Which is greater 0.086 or 86%
cupoosta [38]
Hey there! 

In order to find out which one is greater, lets convert both of them into percents. 

To convert a decimal into a percent, simply multiply the decimal by 100 or move the decimal two places to the right. 

So! 
0.086 × 100 = 8.6%

Now, we know that 0.086 is equal to 8.6% So, the correct answer is 86% 

86% is greater than 0.086.
