Answer:

f + g)(x) = f (x) + g(x)

= [3x + 2] + [4 – 5x]

= 3x + 2 + 4 – 5x

= 3x – 5x + 2 + 4

= –2x + 6

(f – g)(x) = f (x) – g(x)

= [3x + 2] – [4 – 5x]

= 3x + 2 – 4 + 5x

= 3x + 5x + 2 – 4

= 8x – 2

(f × g)(x) = [f (x)][g(x)]

= (3x + 2)(4 – 5x)

= 12x + 8 – 15x2 – 10x

= –15x2 + 2x + 8

\left(\small{\dfrac{f}{g}}\right)(x) = \small{\dfrac{f(x)}{g(x)}}(

g

f

)(x)=

g(x)

f(x)

= \small{\dfrac{3x+2}{4-5x}}=

4−5x

3x+2

My answer is the neat listing of each of my results, clearly labelled as to which is which.

( f + g ) (x) = –2x + 6

( f – g ) (x) = 8x – 2

( f × g ) (x) = –15x2 + 2x + 8

\mathbf{\color{purple}{ \left(\small{\dfrac{\mathit{f}}{\mathit{g}}}\right)(\mathit{x}) = \small{\dfrac{3\mathit{x} + 2}{4 - 5\mathit{x}}} }}

You first need to multiply the whole second equation by to. So, your two equations would then be -8x + 5y = -9 and 8x + 6y = -46. You then add the two equations to get 11y = -55. This would mean you get y = -5. Then you substitute -5 for y in the first equation. This would mean it would be -8x -25 = -9. Then you add 25 to both sides to get -8x = 16. Then you divide both sides by -8 to get x = -2.

Answer:

Points on the graph:

(0, 0)

(1, 4)

(2, 8)

Step-by-step explanation:

Just input the first 4 values for x:

(0, y)

y = 4x

y = 4(0)

y = 0

(1, y)

y = 4x

y = 4(1)

y = 4

(2, y)

y = 4x

y = 4(2)

y = 8

Which is bigger 20% of 300 or 1/4 of 200
worty [1.4K]
To find 20% of 300, multiply .2 x 300 = 60
60 is 20% of 300

1/4 = 25%
to find 25% of 200, multiply .25 x 200 = 50
50 is 1/4 of 200

20% of 300 is more than 1/4 of 200
