evaluate -5 + 2 - 7 (-12) show work

[tex]\huge\bold\green{Answer:-}[/tex]

Area. The amount of space covered by a two-dimensional object; the amount of carpet you'd need to cover a floor would depend on the floor's area.

Perimeter. The distance around a two-dimensional object; the amount of fence you'd need to surround your yard equals the perimeter of your yard. (The perimeter of a circular object is called the circumference.

Volume. The amount of three-dimensional space inside an object; the amount of liquid inside a soda can represents the can's volume.

Surface area. Measures the amount of "skin" needed to cover a three-dimensional object, neglecting its thickness; the amount of siding you'd need to completely cover a house represents the surface area of that house's walls.

Description Formula Variables

Area of a rectangle A = l · w l = length, w = width

Perimeter of a rectangle P = 2(l + w) l = length, w = width

Area of a circle A = r2 r = radius of circle

Circumference of a circle C = 2r r = radius of circle

Volume of a rectangular solid V = l · w · h l = length, w = width, h = height

Volume of a cylinder V = r2h r = radius; h = height

Surface area of a cube SA = 6l2 l = length of side

Answer: y=-4x-31

Step-by-step explanation:

To find a ling that is parallel to the given line and passes through the given point, we need to use the given point. We know that the slope MUST stay the same because parallel lines NEVER touch. All we have to do is plug in the point and find the y-intercept.

-7=-4(-6)+b            [multiply]

-7=24+b                 [subtract both sides by 24]

b=-31

Now, we know that y=-4x-31 is the equation.

Step-by-step explanation:

Given that a t-shirt cost Rs. 375,

then 2 t-shirt will cost Rs. 375*2

=Rs.750

a. the total cost will be

 13*750

=Rs.9750

b. a sponsor pays Rs.7020

  there will be a deficit of

  9750-7020

=2730

since there are 13 players each player will pay

2730/13

Rs. 210

Answer:

Add -3+8

Step-by-step explanation:

You would do this first because it is in the brackets. Usually you would do (*) first but those are just there because the 4 is negative and if they were not there it would get confusing and look like this::[-3+8]--4. So the next step would be the [*].

HOPE THIS HELPS!!!

Answer:

Use PEMDAS

Step-by-step explanation:

Parenthesis, If there are none move on to exponents if there are no exponents move to multiplication. No multiplication? use division. If you dont see division use addition and lastly if there is no addition use subtraction. In the equation, it looks like you have to make the -3 and 8 positive. So, since the -4 is in the parenthesis(P) multiply(M) 4 by 3 and 8 once the three is positive. So your final answer would be either C or D

Its the best i could do but good luck. I tried...

Answer:

The true statemens are:

All function have (at least) a dependent variable. That is why you can write y = f(x), x is the independent variable, while y depends on x values, so y is the independent variable.

All function have and independent variable (explained above).

A horizontal line is an example of a funcitional relationship (because given a value of x, you can always tell the value of y)

The other statements are false:

The range of a function includes its domain is false.

Domain are the values that x can take and the range are the values that the function (y) can take. One is not included in the other.

A vertical  line is an example of a functional relationship is false, because you can not tell the value of y for any value of x.

Each output value of a function can correspond to only one input value is false.  An output can be generated by more than one value of x. The horizontal line is an example of that: the same value of y (output) corresponde to any value of x.

Step-by-step explanation:

Answer:

A: All functions have a dependent variable.

B: All functions have an independent variable.

E: A horizontal line is an example of a functional relationship.

Answer:

  -8

Step-by-step explanation:

If α and β are roots of x^2 +5x +a = 0, then we must have ...

  (x -α)(x -β) = x^2 +5x +a

  x^2 -(α+b)x +αβ = x^2 +5x +a

Then ...

  α + β = -5

Together with the other relation between the roots, we have a system of equations in α and β.

Using the above to write an expression for β, we get ...

  β = -α -5

Substituting this into the given relation, we have an equation for α:

  2α +5(-α -5) = -1

  -3α -25 = -1 . . . . . . eliminate parentheses

  -24 = 3α . . . . . . . . add 3α +1

  -8 = α

The root α is equal to -8.

I've got it!! So domain is x valued and range is y. Domain would be -3 ≤ x < 4 and range would be 1 < f(x) ≤ 6, I'm pretty sure !! because f(x)=y :))

Answer:

Domain x is -3 to 4 but not 4 Range y is 6 to 1 but not 1

There are 60 * 60 * 24 =  86400 seconds in a day

if the light flashes 5 times every 10 seconds, that means it flashes once every 2 seconds.

It follows the flashes in a day are 86400 / 2 = 43200

Answer:

v d m because I got the answer from gogjle

Given parameters:

    x = 150 minus 6 y

Interpreting this gives;

    minus = subtraction  = -

        x  = 150 - 6y

Now bring the variables together;

                    x + 6y  = 150

The option that matches with this equivalent.

The other choices are wrong;

   a,  x + 150 = 6 y

           x - 6y = 150   wrong

 c. 2x + 3y = 75   mulitply through by 2;

      2(2x + 3y) = 2(75)

        4x + 6y  = 150      wrong

   d. 2x - 3y = 75

    Multiply by 2;

     2(2x -3y) = 2(75)

      4x - 6y = 150

Answer:

x+6y = 150 (B)

Answer:

D) It is greater than 1.

Step-by-step explanation:

Since k is greater than 3, it could not be between 0 and 1/3 and also could not be between 1/3 and 1

We also know that it is not equal to 1 because it is greater than 3.

Therefore, it is greater than 1.

Answer:

Squirrel population is 440 squirrels.

Step-by-step explanation:

It is given that there are 22 squirrels are marked.

Later the company returned and counted a total of 220 squirrels of which are marked were 11.

So, we can set up proportional equation to find the squirrel population.

Let squirrel population is x.

We can set up proportional equation as

[tex]\frac{11}{220}=\frac{22}{x}[/tex]

Cross multiply

11 x=4840

Divide both sides by 11

x=440

Best estimate is 440.

Answer:

Alyssa’s lemonade recipe

Step-by-step explanation:

→ Work out how much lemons is needed per gallon for Alyssa’s lemonade recipe

9 lemons = 2.5 gallons

(÷ 2.5)      =     (÷ 2.5)

3.6 lemons = 1 gallon

→ Work out how much lemons is needed per gallon for Brian’s lemonade recipe

12 lemons = 4 gallons of water

(÷ 4)            =    (÷ 4)

3 lemons = 1 gallon of water

→ Now compare

Alyssa’s lemonade recipe ⇒ 3.6 lemons = 1 gallon

Brian’s lemonade recipe ⇒ 3 lemons = 1 gallon of water

Brian's lemonade recipe requires more water.

Alyssa uses 10 gallons of water for 36 lemons. Brian uses 12 gallons of water for 36 lemons. Therefore Brian's lemonade recipe requires more water.
