Answer:

independent is r and dependent is y

Step-by-step explanation:

An independent variable is exactly what it sounds like. It is a variable that stands alone and isn't changed by the other variables you are trying to measure.

a tree grows a ring for each year, therefore, to determine a trees age, you need to count the rings. the rings "r" dictate the age or years "y"

Answer:

(-∞,∞)

Step-by-step explanation:

The domain is all possible x values of the function

There are no constraints or holes for this and therefore the domain is all real numbers

A function is a relationship between inputs where each input is related to exactly one output.

x values can be ........-5,-4,-3,-2,-1, 0, 1, 2, 3, 4, 5, 6,.........

The reasonable domain for the function f(x) = 10x + 8 is (-∞, ∞).

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

f(x) = 10x + 8

We can have any real values of x.

f(-2) = -20 + 8 = -12

f(-1) = -10 + 8 = -2

f(1) = 10 + 8 = 18

f(2) = 20 + 8 = 28

f(3) = 30 + 8 = 28

.

.

.

x values can be ........-5,-4,-3,-2,-1, 0, 1, 2, 3, 4, 5, 6,.........

So,

The domain of the function f(x) = 10x + 8 is -∞ to ∞.

We can write as an interval as,

(-∞, ∞).

Thus,

The reasonable domain for the function f(x) = 10x + 8 is (-∞, ∞).

Answer:

The solution of the given equations

x = 3 and y =-2.5

Step-by-step explanation:

Step(i):-

  x - 2y = 8 ..(i)

3x = 19 +4y ..(ii)

By using substitution method

substituting  x = 2y +8 in equation (ii)

 ⇒  3( 2y +8) = 19 +4y

⇒   6y +24 = 19 +4y

⇒  6 y - 4y = 19 - 24

⇒   2 y = -5

   [tex]y = \frac{-5}{2} = -2.5[/tex]

Step(ii):-

Substitute 'y' = -2.5 in equation (i) , we get

         x - 2y = 8

   ⇒  x - 2( [tex]\frac{-5}{2}[/tex]) =8

  ⇒  x = 8 -5

      x = 3        

Final answer:-

The solution of the given equations

x = 3 and y =-2.5

Answer: 6 gifts.

Step-by-step explanation:

I found the question elsewhere and it states that Eve needs 2/3 m for each gift.

Since Eve has 4 m, the number of gifts she can wrap is the 4 m she has divided by the 2/3 m required for each gift.

= 4 ÷ 2/3

= 4 × 3/2

= 12/2

= 6 gifts.

Note: When dividing by a fraction, you can multiply by it's inverse.

Answer:

Step-by-step explanation:

The supplement to ∠1 = 180°-135° = 45° = ∠3, so m is parallel to j and l.

∠2 ≠ 45° and ∠2 ≠ 135°, so k is not parallel to j, l, or m.

Answer:

[tex]h= 2x[/tex]

Step-by-step explanation:

Given

Square

[tex]Side = x[/tex]

Triangle

[tex]Base = x[/tex]

[tex]Altitude = h[/tex]

Required

Find h, if both shapes have the same area

The area of the square is:

[tex]Area = x * x[/tex]

[tex]Area = x^2[/tex]

The area of the triangle is:

[tex]Area = \frac{1}{2} * Base*Height[/tex]

[tex]Area = \frac{1}{2} * x*h[/tex]

Equate both areas

[tex]x^2 = \frac{1}{2} * x*h[/tex]

Divide both sides by x

[tex]x = \frac{1}{2} *h[/tex]

Multiply both sides by 2

[tex]2*x = \frac{1}{2} *h*2[/tex]

[tex]2x = h[/tex]

[tex]h= 2x[/tex]

Answer:

D

Step-by-step explanation:

We can safely assume we are dealing with an arithmetic scale because the type of scale isn't mentioned anywhere. The more right a point is on the scale, the higher its value is. We are given two points of the scale: 3 and 4. Because the scale is arithmetic, we know that 3.8 must lie on 4/5s of the length between 3 and 4 to the right of 3, which is exactly where point D is.

Step-by-step explanation:

Answer:

k = 3

Step-by-step explanation:

Given that b varies jointly with c and d and inversely with f then the equation relating them is

b = [tex]\frac{kcd}{f}[/tex] ← k is the constant of variation

To find k use the condition c = 4, d = 9, f = 6 , b = 18, then

18 = [tex]\frac{k(4)(9)}{6}[/tex] = [tex]\frac{36k}{6}[/tex] = 6k ( divide both sides by 6 )

3 = k

Answer:

90 cm

Step-by-step explanation:

Given that :

Perimeter of a rectangle = 2(Length + Width)

Perimeter of print area = 2(100 + 140) = 480cm

Perimeter of entire poster :

Let uniform width of blank strip = x

x on each of the 4 sides side ;

2(2x + 100 + 2x + 140)

2(4x + 240)

8x + 480

Perimeter of poster = 1 2/3 perimeter of print area

8x + 480 = 5/2(480)

8x + 480 = 1200

8x = 1200 - 480

8x = 720

x =. 720 / 8

x = 90 cm

Answer:

8 1/2 cup servings

Step-by-step explanation:

Hello!

Well to solve this we have to take the total amount of cups of ice cream and divide it amongst the servings.

So :

Total = 4 cups

Serving = 1/2 cup

What we can do since its such a lower number is count it out by increments of 1/2.

Like so :

So, in total, there would be 8 servings of half a cup of ice cream in 4 cups.

I hope this helps!

If you have any questions or concerns feel free to message me or comment! :)

The number of 1/2 ­cup servings are in 4 cups of ice cream are 8.

A division is a process of splitting a specific amount into equal parts.

We need to find the number of 1/2 ­cup servings are in 4 cups of ice cream

A half cup serving is equal to 4 fluid ounces.

Therefore, 4 cups of ice cream is equal to 8 half-cup servings,

since 4 cups is equal to 32 fluid ounces and 32 divided by 4 equals 8.

4/(1/2)

4×2

8 cups

Hence, the number of 1/2 ­cup servings are in 4 cups of ice cream are 8.
