F(2)=7(2)-5=14-5=9
g(4)=4(4)=16
f(2)-g(4)=9-16=-7

Do you see that when we change

f(x) = 7x - 5 

to 

f(2) = 7(2) - 5

we are simply saying to substitute in 2 for x? Well that is what we are doing:

f(2) = 7(2) - 5

f(2) = 14 - 5

f(2) = 9 

Now we find g(4) the same way:

g(x) = 4(x)

g(4) = 4(4)

g(4) = 16

Now we find the difference of the two functions:

f(2) - g(4)

9 - 16

-7

So, the answer is B.

Goshia [24]
Y = mx+b (slope intercept form). I imagine the point is (2,2) and m = 0. So the answer is y = 2. A sketch would be a horizontal line on the x-y plane going through (2,2).

A gym charges a monthly fee and an additional cost for each class. Consider the graph that represents the relationship between t
bija089 [108]
For this problem you need to understand that a linear graph is a straight line (Remember Rise/Run). 
A continous function is <span>a </span>continuous function<span> is a </span>function <span>for which sufficiently small changes in the input result in arbitrarily small changes in the output, so we can already cross off that as an answer.
The Y-Intercept is the cost (in dollars), so this would be to monthly fee. 
Now, onto the rate of change. T</span>he rate of change is <span>represented by the slope of a line. So the more classes you take the more it will increase. Therefore the cost for  one class is the rate of change. 
Lastly, the cost for one class is $10. It's not, since $10 is the intial fee to belong to a gym, so this is false. 

Recap:
True
-The relationship is linear
-The y-intercept represents the monthly fee.
-The rate of change represents the cost for one class.
False
-The relationship represents a continuous function. 
-The cost for one class is $10.

Round it to nearest fifths​
Yanka [14]

Answer:

mean = $11.15

median = $11.30

mode = $9.90, $10.70, $11.90, $12.05

Step-by-step explanation:

Ordered from smallest to largest

9.89, 10.71, 11.90, 12.06

The mean is the middle number.

There are two numbers in the middle so you have to add them together and divide by 2.

(10.71 + 11.90)/2 = 11.305

rounded 11.30

Mode is the number that appears the most. All of the prices are listed once. They are all the mode.

Mean is (10.71+11.90+9.89+12.06)/4 = 11.14

round 11.15

Solve angle X to 1 dp
geniusboy [140]

Answer:

x ≈ 57.8°

Step-by-step explanation:

using the Sine rule in the triangle

\frac{11}{sinx} = \frac{8}{sin38} ( cross- multiply )

8 × sinx = 11 × sin38° ( divide both sides by 8 )

sinx = \frac{11sin38}{8} , then

x = sin^{-1} ( \frac{11sin38}{8} ) ≈ 57.8° ( to 1 dec. place )
