Answer:

A.) 3:5

Step-by-step explanation:

Apples to plums:

9:15

You can simplify this by dividing both numbers by 3:

Is N² + N always an even number? Explain
qaws [65]

Answer:

Yes

Step-by-step explanation:

Yes.

Let's first start with even numbers. (N - even number)

Any even number squared, is an even number. Then, we add that squared even number to another even number which would give us an even number.

Now, let's see odd numbers.

Any odd number squared would be an odd number. When you add "N", it would be adding an odd number to an odd number, which gives you an even number.

OR

We can start by factoring the expression:

N^2+N=N(N+1)

This is essentially multiplying two consecutive numbers, which in turn means that one number has to be even, and one has to be odd. An odd number multiplied by an even number will always be even.

3 (x-k)/w = 4 solve for x
Trava [24]
<span>Actually the above equation can be solved by following the below steps to fins the value of x Step1: 3(x-k)/w=4 Step 2: (3x-3k)/w=4 Step 3: (3x-3k)=4w Step 4: 3x=4w+3k So hence therefore by following the above steps we can conclude that the value of x is Step 5: x=(4w+3k)/3</span>

Which is an equation of a direct proportion?<br><br> a.y=1/6x+6 b.y=6/x<br> c.y=6x-6 d.y=6x
Amanda [17]

Answer:

Option D. y=6x

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form y/x=k or y=kx

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

<em>Verify each case</em>

case a) y=(1/6)x+6

Is a linear equation, but is not a direct variation. The line not passes through the origin

case b)  y=6/x

The equation represent an inverse variation

case c) y=6x-6

Is a linear equation, but is not a direct variation. The line not passes through the origin

case d) y=6x

The equation represent a direct variation
