Step-by-step explanation:

The vertex is the turning point of the quadratic function.

In this case it lies on the x- axis at (2, 0 ) → B

Take your time! :) Not important, but I would like to know, I'm writing flashcards so I can remember when I start back in school

Answer:

The LCM of two numbers is the least common multiple. You want to find the least possible number that is divisible by the two numbers. So, you can list the factors of the two numbers. If there are factors that are repeated, put the repeated factors to the side. With the remaining factors, multiply the factors by each other and the repeated factors.

For example, let's try to find the least common multiple between 10 and 15.

Factors of 10: 2 * 5

Factors of 15: 3 * 5

The repeated factor is 5.

2 and 3 are left over. 2 * 3 = 6. 6 * 5 = 30. So, that is the least common multiple.

The GCF of two numbers is the greatest common factor. You want to find the greatest factor that is included in both numbers. So, again, you can list the factors of the two numbers and find the greatest factor that is repeated between the two numbers.

For example, let's try to find the greatest common factor between 30 and 45.

Factors of 30: 1, 2, 3, 5, 6, 10, 15, 30

Factors of 45: 1, 3, 5, 9, 15, 45

Between the two numbers, shared factors are 1, 3, 5, and 15. So, the greatest common factor is 15.

Hope this helps!

Which function has the greatest rate of change? A. x y 3 3 4 6 5 9 B. y = 4 + 6x C. 12x + 6y = 18 D. A linear function that goes

Alex787 [66]

Answer:

B. y = 4 + 6x

Step-by-step explanation:

We know that the rate of change of a straight line is equal to the slope of the line.

Now, the general form of a straight line is y = mx + b, where m is the slope and b is the y-intercept.

Also, the slope of a line joined by $( x_{1},y_{1} )$ and $( x_{2},y_{2} )$ is given by $m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$ .

So, using these, we will find the slopes of the lines given in the options.

A. Here, we are given two points (3,3) and (4,6). Then, the slope is given by,

$m_{1}=\frac{6-3}{4-3}$ i.e. $m_{1}=3$ .

B. We have the equation of line y = 4 + 6x. On comparing it with the general form, we get that the slope is 6 i.e. $m_{2}=6$ .

C. We are given the standard form of a line. First, we convert it into the slope-intercept form ( or the general form ).

i.e. 12x + 6y = 18 → 2x + y = 3 → y = -2x + 3

Now, on comparing this equation with the general form of a line, we get that the slope is -2. i.e. $m_{3}=-2$ .

D. Here, we are given a linear function passing through (1,-1) and (0,4). Then the slope is given by,

$m_{1}=\frac{4+1}{0-1}$ i.e. $m_{4}=-5$ .

Hence, we obtain that the function y=4+6x has the greatest slope or the greatest rate of change i.e. $m_{2}=6$ .
