Which table represents a direct variation function?

Answers

Answer 1

Answer:

(A) First table

___________

Input: 6, 9, 12

Output: 8, 12, 16

Step-by-step explanation:

To determine whether or not a function is a direct variation, x and y must divide evenly and have a constant factor or factor that stays the same.

B and C don't divide evenly so those are already wrong, and D is wrong because x and y do not divide by the same factor every time.

find x and y

Answers

Answer:

x=-3/2y+2

y= y=−3x+6

Step-by-step explanation:

solve for x.

2x+3y=4

Add -3y to both sides.

2x+3y+−3y=4+−3y

2x=−3y+4

Divide both sides by 2.

2x/2= -3+4/2

x= -3/2 y+2

solve for y.

y+3x=6

Add -3x to both sides.

3x+y+−3x=6+−3x

y=−3x+6

Answers

Answer:

x^2 - 4x + 5 = 0

Step-by-step explanation:

x = (2 + i) and (2 - i) are the roots of the quadratic equation f(x) = x² - 4x + 5.

What are roots of a quadratic equation?

The values of variables satisfying the given quadratic equation are called its roots.

Given (2 + i) and (2 - i) are roots of the quadratic equation.

Let the quadratic equation be f(x).

(x - (2 + i)) and (x - (2 -i)) are the factors of f(x).

Since, f(x) is a quadratic equation, it has only two roots.

f(x) = (x - (2 + i))(x - (2 - i))

f(x) = x² - (2 - i)x - (2 + i)x + (2 - i)(2 + i)

f(x) = x² - 2x + ix - 2x - ix + 4 - i²

f(x) = x² - 4x + 4 + 1

f(x) = x² - 4x + 5

During the morning commute 60 cars and 12 trucks passed through the intersection. What is the ratio of cars to trucks?

Answers

Answer: 60:12, 60/12, or 60 to 12.

Step-by-step explanation:

To find the ratio, we must find 2 values. The values in this case is 60 and 12. 60 being cars and 12 being trucks.

So to write the ratio, we must put the cars first, then the trucks second.

So 60 first, and 12 second.

And remember, there are 3 ways to write ratios.

So we can write it like 60:12, 60/12, or 60 to 12.

The answers are 60:12, 60/12, or 60 to 12.

What is a formula for the nth term of the given sequence? 48, 72, 108

Answers

Answer:

[tex]a_n=48*1.5^{n-1}[/tex]

Step-by-step explanation:

Geometric Sequence

In geometric sequences, each term is found by multiplying (or dividing) the previous term by a fixed number, called the common ratio.

We are given the sequence:

48, 72, 108, ...

The common ratio is found by dividing the second term by the first term:

[tex]r=\frac{72}{48}=1.5[/tex]

To ensure this is a geometric sequence, we use the ratio just calculated to find the third term a3=72*1.5=108.

Now we are sure this is a geometric sequence, we use the general term formula:

[tex]a_n=a_1*r^{n-1}[/tex]

Where a1=48 and r=1.5

[tex]\boxed{a_n=48*1.5^{n-1}}[/tex]

For example, to find the 5th term:

[tex]a_5=48*1.5^{5-1}=48*1.5^{4}=243[/tex]
