Answer:

The missing value is -9

Step-by-step explanation:

Given

-7 = _ -(-2)

Required

Determine the missing value

Represent _ with a variable

-7 = x -(-2)

Open the bracket

-7 = x -1*-2

-7 = x + 2

Subtract 2 from both sides

-7 - 2 = x + 2 - 2

-9 = x

Reorder

x = -9

<em>Hence, the missing value is -9</em>

6) A sample of water is being cooled according to the formula is given by
Vinvika [58]

Answer:

Relevant domain: [0 40]

Relevant range: [0 80]

Step-by-step explanation:

We have the following function:

C(t) = 80 - 2t

In which C(t) is the water temperature.

t is the time.

The colling period ends when the water freezes (0°).

So it freezes after t minutes, and t is found when C(t) = 0. So

C(t) = 80 - 2t

80 - 2t = 0

2t = 80

t = \frac{80}{2}

t = 40

Relevant domain:

Input value of the function, which is in minutes. So between 0(initial) and 40(when the water freezes).

Relevant range:

Initial temperature, which is C(0) = 80, until it freezes, 0. So from 0 to 80.

Let number of large bags be x

Teddy will buy at least 15 bags of ice for the graduation picnic.

Each large bag of ice costs $4.00, and each small bag of ice costs $2.50. He will spend up to $50 on ice. The set of inequalities that describe this scenario are

4x + 2.5y lesser than or equal 50

x + y greater than 15

The combination of bags of ice that Teddy can buy is

b) 6 large bags and 10 small bags

From the option b, the total number of large and small bags is greater than 15 and the total cost is 49( it doesn't exceed 50)

triangle RST had coordinates: R(-2, 1) S(-8, 2) T(-4, 5) Draw the translation of RST 8 units right and 4 units down on your reco
DedPeter [7]

Since the translation is 8 units right and 4 units down, we have to add 8 to the x coordinate and subtract 4 to the y coordinate.

R=(-2,1)

R' = (-2+8,1-4)= (6,-3)

R' = (6,-3)
