Answer:

687

Step-by-step explanation:

Answer:

k = 575

Step-by-step explanation:

let d be distance and h time.

Given d varies directly as h then the equation relating them is

d = kh ← k is the constant of variation

To find k use the condition d = 2875, h = 5, then

2875 = 5k ( divide both sides by 5 )

k = 575

Answer:

x = 5

Step-by-step explanation:

This equation can be rearranged in order to easily solve.

First, rearrange the equation by simply flipping it.

3x + 30 = 9x → 9x = 3x + 30

Then, you may solve for x.

9x = 3x + 30 subtract 3x from both sides of the equation

6x = 30 divide by 6 on both sides of the equation

x = 5

Answer:

The Independent Variable is the variable or thing that depends on nothing, nothing can affect it, nor can it be changed by any other variables, in this case the Independent variable is the Fish tank, the fish tank depends on nothing, and will stay the same.

The Dependent Variable is the variable or thing that depends on one or more variables in the equation, it be changed by any other variables, in this case the dependent variable is the fish, the fish depend on the water in the tank.

Answer:

0

Step-by-step explanation:

Note that + (- 7) = - 7 , thus

- 18 + (- 7) + 25 = - 18 - 7 + 25 = - 25 + 25 = 0

Answer:

see below for corrections

Step-by-step explanation:

equation A: 5(1 - 6) + 3r = (21 - 8)

5(-5) + 3r = 13

-25 + 3r = 13

3r = 38

r = 12.667

equation B: 2.7(5.11 + 4.9) = 3.2 + 28.9

2.7(10.01) = 32.1

27.027 = 32.1

no solution (are you missing a variable somewhere?)

Hope this helps ;) ❤❤❤

Answer:

-2n + 6

Step-by-step explanation:

Combine like terms (terms with the same amount of variables).

Note the laws of signs:

Two additions signs: If there are two addition signs directly next to each other (which will not be shown very much), it means to add.

One addition sign & One negative sign: If there is one of each signs directly next to each other (as shown here), you must default it to negative and subtract.

Two negative signs: If there are two negative signs directly next to each other, you must default it to positive and add.

First, change the expression to signify how you should combine the terms:

5n + 6 + (-7n) = 5n - 7n + 6

Combine like terms:

(5n - 7n) + 6

-2n + 6

-2n + 6 is your answer.

Step-by-step explanation:

Answer:

100

Step-by-step explanation:

V (x) = 5x²+ 5x

x=4

We plug in the x value:

V (x) = 5(4)²+ 5(4)

Now we sovle the equation:

5(4)² + 5(4)

5(16) + 5(4)

80 + 20

= 100

Answer:

1/7 is greater than 1/8 so 1/7 must go after it. but negative is always less then positive so the correct order is

-1/8, -1/7, 1/8, 1/7

The numbers arranged in increasing order is

-1/8, -1/7, 1/8, 1/7

There are 4 values given:

1/7, 1/8, - 1/7, - 1/8

Negative figures are generally lesser than positive figures

1/7 is greater than 1/8

In negative values, the greater number becomes the smaller number

Therefore,

-1/8 is the the smaller number

Arrangements in increasing order =

-1/8, -1/7, 1/8, 1/7

1 = (3,2) B= (6, 6) C = (6, -3)

Move two to the right since left and right deals with the x axis, add two to the x’s

2 = (1, -2) B = (4, -6) C = (4, 3)

Reflecting across the x axis means the formula is (x, -y) so switch the sign of the y’s

Answer:

1) A (3,2), B (6,6), C (6,-3)

2) A (1,-2), B (4,-6), C (4,3)

Step-by-step explanation:

1) Each of the x-values goes up two.

A (1,2) becomes (3,2)

B (4,6) becomes (6,6)

C (4,-3) becomes (6,-3)

2). I assume they mean the ORIGINAL ABC, not the one you just translated 2 units to the right.

To do this, you just multiply each y-value times negative one.

A (1,2) becomes (1,-2)

B (4,6) becomes (4,-6)

C (4,-3) becomes (4,3)

Step-by-step explanation: A ratio which compares a whole coin collection to a part of it would be expressed in such a way that, the numerator will be the part of the coin which is being compared and the denominator being the value of the entire coin. Mathematically, It could be expressed in proportion form as ;

(Part or amount of the coin which is being compared / total value of entire coin)

A / B such that;

A = value or amount of coin which is being compared.

B = value of the entire coin.

Or in the form

A : B

Answer: Reflection across the x-axis and Vertical stretch are the ones that return an odd function.

Step-by-step explanation:

An odd function f(x) is a function such that:

f(-x) = -f(x).

So let's analyze the options:

A) Horizontal translation.

An horizontal translation of A units to the right (A > 0) is written as:

g(x) = f(x  - A)

Now, let's see if g(x) is also odd.

g(x) = f(x - A)

g(-x) = f(-x - A)

Now, f(-x - A) is equal to -f( x + A)

then:

g(-x) = f(-x - A) ≠ -g(x) = -f(x - A)

This is not an odd function.

B) Reflection over the x-axis.

When we have a point (x, y), a reflection over the x-axis changes the sign of the y-variable.

Then we have that:

g(x) = -f(x).

Then:

g(x) = -f(x)

g(-x) = -f(-x) = -(-f(x)) = f(x)

then:

g(x) = -f(x) = -g(-x)

This is an odd function.

C) Vertical stretch:

We can write a vertical stretch of factor scale A as:

g(x) = A*f(x).

Let's see if g(x) is odd:

g(-x) = A*f(-x) = A*(-f(x)) = -A*f(x) = -g(x)

this is a odd function.

C) Vertical translation:

A vertical translation of A units up (A > 0) is written as:

g(x) = f(x) + A.

Similar to the case of the horizontal translation, so it is easy to see that g(x) is not an odd function.

Answer:

-5

Step-by-step explanation:

Coordinate of A = -7

Coordinate if B = 5

Distance of AB = |-7 - 5| = |-12| = 12

We are asked to find the coordinate of the point that would be ⅙ from the A to B, which is ⅙ of AB.

Let's find what ⅙ of AB is.

AB = 12

Therefore, ⅙ of AB = ⅙*12 = 2.

From point A (-7), we move 2 points towards B which will give us ⅙ from A to B.

The coordinate = -7 + 2 = -5

-5 is the coordinate of the point with a fraction distance of ⅙ from A to B.

Answer:

[tex]\sqrt{20}[/tex]

Step-by-step explanation:

To find the Apothem of a shape, we need to find how long the distance is from a vertex to the center of the shape.

We can see that they've already showed us how to do it: We need to find the length of the hypotenuse of the red triangle.

To do this, we can use the Pythagorean Theorem, which states that [tex]a^2 + b^2 = c^2[/tex].

We know that a is going to be half of 4, which is 2. We also know that b is going to be 4, so we can substitute inside the equation.

[tex]2^2 + 4^2 = c^2\\\\4 + 16 = c^2\\\\20=c^2\\\\c=\sqrt{20}[/tex]
