6x^2 + x - 15 = 6x^2 - 9x + 10x - 15 = 3x(2x - 3) + 5(2x - 3) = (3x + 5)(2x - 3)
Therefore, the other factor is 3x + 5.

Point A is located at (3, 6) and point B is located at (10,−2) .

<u>Answer:</u>

(4.75, 4)

<u>Step-by-step explanation:</u>

We are to find the coordinates of the point that partitions the directed line segment AB in 1:3 ration.

For this, we will use the following formula:

$x = x_1 + k(x_2 - x_1)$ , $y = y_1 + k(y_2-y_1)$

where $k$ is the ratio of the first segment to the whole line segment so in this case, it will $\frac{1}{4}$ .

So substituting the given values in the above formula to find the coordinates:

$x = 3 + \frac {1}{4} (10-3) = 4.75$

$y = 6 + \frac{1}{4} (-2-6) = 4$

Therefore, the coordinates of the point that partitions the directed line segment AB in a 1:3 ratio are (4.75, 4).

Laura is building a fence around her pond. The pond has a diameter of 5 ft. Which is the minimum amount of fence Laura will need

aivan3 [116]

Answer: 15.707 feet of fence.

Explanation: The formula to find this would be the one you’d use to find circumference, which is: C = 2(Pi)r

Half of the diameter is the radius, so plug that in and it becomes:

C = 2(pi)2.5

Then you just solve it and the result is C = 15.707

4 bells toll together at 9 am. They toll after 7, 8. 11 and 12 seconds respectively. How many times will they toll together agai

Svetach [21]

Answer:

5 times

Step-by-step explanation:

What we need to do here is to find the lowest common multiple of 7,8,11 and 12

This is;

1848

Now, let’s calculate the number of seconds in 3 hours

In 1 hour, we have 3600 seconds

In 3 hours, this will be;

3600 * 3 = 10,800 seconds

So, to find the number of times in which all 4 will toll together, we need to know the number of 1848 seconds in 10,800 seconds

Mathematically, that will be;

10,800/1848 = 5.844

Our answer will be 5 times however

This is because the sixth time they would have sounded together would be more than the 3 hours time frame

I have to write the definitions of all of these math terms, can you help me?

EastWind [94]

Answer:

Solution of an Equation in Two Variables - Generally, a two-variable system solution is an ordered pair that makes BOTH equations valid.

Graph of an Equation in Two Variables - In the Ax + By = C form, linear equations with two variables will appear, and the resulting graph is always a straight line.

Linear Equation - Any equation that can be written in shape is a linear equation. Ax+b=0, 0.0 Where the real numbers are a and b, and x is a vector.

Linear Function - Those whose graph is a straight line are linear functions. The following form has a linear function. F(x) = y = a + bx.
