For this case, we have that by definition, be given two functions f (x) and g (x). So:

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

We have:f (x) = - 3x-5\\g (x) = 4x-2

So:

(f-g) (x) = - 3x-5- (4x-2)

We have to:

- * + = -\\(f-g) (x) = - 3x-5-4x + 2

Equal signs are added and the same sign is placed while different signs are subtracted and the sign of the greater is placed

(f-g) (x) = - 7x-3

Answer:

Option D

On your family trip, you used 14 gallons of gas.
Alecsey [184]

Answer:

19

Step-by-step explanation:

To get the total miles you drove first, you need to do 84947 (number after the trip) - 84679 (the number before it. You get 268.

Next you need to find out how many miles per gallon. 268/14 which will equal to 19.142, which you can round to 19.

100 POINTS FOR BOTH SIDES PLZZZ Plzzz help me with this SIDES
Oliga [24]

Answer:

Step-by-step explanation:

5.

point = (x, y)

A = (1\frac{1}{2}, 12)

B = (2\frac{1}{2}, 20)

C = (3, 24)

D = (3\frac{1}{2}, 28)

y/x ratios

\frac{12}{1\frac{1}{2} }

\frac{20}{2\frac{1}{2} }

24/3

\frac{28}{3\frac{1}{2} }

6.

(1 2/3, 3 1/3) = 3 1/3 ÷ 1 2/3 = 2

(1 1/4, 2 1/2) = 2 1/2 ÷ 1 1/4 = 2

(3, 7) = 7 ÷ 3 = 2 1/3

(4 1/2, 9) = 9 ÷ 4 1/2 = 2

The ratio 7/3 (x = 3 and y = 7) is not proportionally related to the others.

The other ratios are equal to each other and are therefore in proportion.

7. yes

Answer:

d = 10/72

Step-by-step explanation:

c and d vary inversely

c = k/d

Where,

k = constant of proportionality

d = 2/9 when c = 5

c = k/d

5 = k ÷ 2/9

5 = k × 9/2

5 = 9k/2

Cross product

5*2 = 9k

10 = 9k

k = 10/9

c = k/d

c = 10/9 ÷ d

c = 10/9 × 1/d

c = 10/9d

find d when c = 8

c = 10/9d

8 = 10/9d

Cross product

8*9d = 10

72d = 10

d = 10/72
