Answer:

(f - g) (x)

Step-by-step explanation:

Since (x) is common between them, you can bring it out. for example,

f(x) = x +1

g(x) = 2x + 3

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

= -x + 4

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

= -x + 4

It basically means that you subtract the sum of f(x) to the sum of g(x) with the given variable or if no variable is given then just subtract the general equations

Step-by-step explanation:

An example ig to help explain(?)

F(x)-g(x), x=3

F(x)=2x-2

G(x)=x

F(x): 2(3)-2=4

G(x): 3

So f(x)-g(x): 4-3=1

Thus the answer to f(x)-g(x) for when x=3 is 1

Please give me the answer to number 5 and explain how to do it.

Goryan [66]

The equation is simply 8s where s is the length of a side. There are 8 sides. You are just adding the length of all 8 sides together to get the perimeter.

What is the domain of f?

Sedbober [7]

The domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0.

Surface area... help me

alexandr402 [8]

Answer: Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.

Determine the x-intercept and y-intercept of the following linear equations

Blizzard [7]

Answer:

Step-by-step explanation:

the x intercept takes coordinate (x,0)

the y intercept takes coordinate (0,y)

x intercept y intercept

40: x+y=5 (5,0) (0,5)

x=0 , y=5, when y=0 x=5

41: x-y=5 (5,0) (0,-5)

x=0, -y=5 then y=-5, when y=0, x=5

42: 3x+4y=12 (4,0) (0,3)

x=0, 4y=12⇒y=12/4⇒y=3

y=0, 3x=12⇒x=12/3⇒x=4

43: 2x+3y=6 (3,0) (0,2)

x=0 , 3y=6⇒y=6/3=2

y=0 ,3y=6 ⇒ y=6/3 ⇒y=2

44: 3x+4y=-24 (-8,0) (0,-6)

x=0 , 4y=-24⇒y=-24/4 ⇒ y=-6

y=0 , 3x=-24⇒ x=-24/3⇒x=-8

45: 1/3x+2/3y=5/6 (5/2,0) (0,5/4)

x=0 , 2/3 y=5/6 ⇒12y=15 ⇒ y=15/12 ⇒y=5/4

y=0 , 1/3 x=5/6 ⇒6x=15 ⇒x=15/6 ⇒x=5/2

46: x=-2 (-2,0) no y intercept

it is vertical line , there is no y intercept

47: y=15 no x intercept (0,15)

horixzontal line, no x intercept

48: 3x-7y=8 (8/3,0) (0,-8/7)

x=0 , -7y=8 ⇒y=-8/7

y=0 , 3x=8 ⇒x=8/3
