<u>Answer:</u>

( f - g ) ( x ) = x - 3

<u>Step-by-step explanation:</u>

We are to find ( f - g ) ( x ) given that f ( x ) = 3 x - 2 and g ( x ) = 2 x + 1.

So basically we have to subtract the function g from function f.

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

Substituting the given functions in the above equation to get:

( f - g ) ( x ) = (3x - 2) - (2 x + 1 )

( f - g ) ( x ) = 3x - 2 - 2 x - 1

( f - g ) ( x ) = 3x - 2 x - 2 - 1

( f - g ) ( x ) = x - 3

Answer:

(f-g)(x) = x-3

Step-by-step explanation:

Given

f(x) = 3x-2

and

g(x) = 2x+1

We have to find (f-g)(x)

So,

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

= 3x-2 - (2x+1)

= 3x-2-2x-1

=x-3

Hence,

(f-g)(x) = x-3

The graph shows the altitude of a helicopter over time. A graph measuring altitude and time. A line runs through coordinates (0,
TiliK225 [7]

We can calculate for the slope of the line using the formula:

m = (y2 – y1) / (x2 – x1)

 

From the given values:

m = (4,000 – 10,000) ft / (15 – 0) min

m = -400 ft/min

This means that the altitude is decreasing by 400 ft per minute.

 

 

> The slope is –400 . This means that the helicopter descends 400 ft each minute.

What is the y-intercept of the line given by the equation below? Enter you answer as an ordered pair.
NikAS [45]

Answer:

0, 7 )

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 8x + 7 ← is in slope- intercept form

with y- intercept c = 7 ⇒ (0, 7 )

in a school ,the number of boys who play cricket is 3 times as much as a number of boys who play tennis. if 12 boys, who play cr
Ierofanga [76]

Answer:

The number of boys who play tennis is 36.

Step-by-step explanation:

Let the number of boys who play tennis is x.

number of boys who play cricket = y

x = 3 y..... (1)  

12 boys plays both cricket and tennis.

According to the question,

x - 12 = y + 1 2

3 y - 12 = y + 12

2 y = 24

y = 12

So, the number of boys who plays tennis is x = 3 x 12 = 36.

If the end points of the diameter of a circle are (9,4) and (5,2) what is the standard form equation of the circle
timurjin [86]

Answer:

(x - 7)² + (y - 3)² = 5

Step-by-step explanation:

The center (h , k) is the midpoint of two end points of diameter

h = (9 + 5) / 2 = 7

k = (4 + 2) / 2 = 3

Equation of circle: (x - h)² + (y - k)² = r²

r = (√(9 - 5)² + (4 - 2)²) / 2 = √5

Equation: (x - 7)² + (y - 3)² = 5
