Answer:

a. 4

b. -8

c. -2

Step-by-step explanation:

Take any number x;

Its opposite is -x

The opposite of its opposite is x

Using the above statements, we can solve the following questions

Solving (a): -4

In this case:

x = -4

The opposite; -x is

-x = -(-4)

-x = 4

Solving (b): 8

In this case:

x = 8

The opposite; -x is

-x = -8

Solving (c): -2

In this case:

x = -2

The opposite; -x is

-x = -(-2)

-x = 2

The opposite; -(-x) is

-(-x) = -2

x = -2

A box contains 8 yellow, 3 orange and 5 purple candies. A tray contains 7 red, 4 blue and 9 orange drinks. If Asia chooses one c
gayaneshka [121]
Okay so we have to first find the total.
8+3+5= 16 candies
7+4+9= 20 drinks
Since she wants to get a yellow candy and any drink but orange, put that information as a fraction.
8/16= 50% or 1/2
11/20= 55% (By the way you get 11 because of the 7 red and 4 blue).
And that's your answer!
Hope this helped and good luck! ^=^

Which representation has a constant of variation of -2.5
Neporo4naja [7]

Answer:

See explanation

Step-by-step explanation:

The constant of variation is found using the slope formula:

\frac{y_2-y_1}{x_2-x_1}

The given relation is

X : -2 , -3, -4, -5  

Y : -5, -7.5,-10,-12.5

We can use any two ordered pair to find the constant of variation.

Using (-2,-5) and (-3,-7.5), we have

m=\frac{-7.5--5}{-3--2} =\frac{-2.5}{-1} =2.5

The constant of variation is 2.5

We need to repeat this for all the options to identify the one with -2.5 as slope.

unfortunately, you did not provide the remaining options.
