Answer:

T(-4) = -(-4)-2 = 2

Step-by-step explanation:

If you have -4 as the x value, all you have to do is substitute -4 in for x in the equation you are given, so it would be -(-4)-2. Now, you have a negative outside of your parenthesis -4, so that will have to be distributed to the -4, and it becomes positive 4. That will then make the equation 4-2, which then makes 2 your overall answer.

"Quantitative" information is information that consists of numbers
and tells you the measure (quantity) of something.

The cost, mileage, and weight of the car are all quantitative items.

The model of the car may have numbers in it, but it doesn't tell
the measure of anything.  It isn't quantitative data.

Answer:

if u have any doubts feel free to ask :)

Step-by-step explanation:

Sum of ratio : 9 + 7 + 4 = 20

a)

Adele share :

                   \frac{9}{20} \times 680 = 9 \times 34 = \$ 306

b)

Barbara share :

                    \frac{7}{20} \times 680 = 7 \times 34 =\$ 238

Collette share :

                     \frac{4}{20} \times 680 = 4 \times 34 = \$ 136

c)

    $            €

 1.125           1

 306            x

    \frac{1.125}{306} = \frac{1}{x}          [cross multiply]

x =\frac{ 306} {1.125}

x = €272

Adele receives = €272

d)

Apple        Cost

 1 kg         2.69

 5 kg          y

y = 2.69 x 5 = $13.45

Cost of 5kg of apples = $13.45

Cost of 3 kg bananas = 17.56 - 13.45 = $4.11

Banana             Cost

  3kg                 4.11

   1 kg                 z

   

  z = \frac{4.11}{3}

z = $1.37

Cost per kilogram of banana = $1.37

e) Collette share = $136

Half of it on clothes = (1/2) x 136 = $68

(1/5) of her share on books = (1/5) x 136 = 27.20

Balance amount with her = 136 - 27.20 - 68 = $ 40.80
