Simplify the product using FOIL. (2x – 7)(5x 5)

Answers

FOIL is an 'acronym'. It helps you remember how to multiply
two binomials ... like (2x-7) and (5x+5) .

FOIL stands for "First, Outside, Inside, Last". Here's how it's used
to multiply these particular two binomials:

   (2x - 7) (5x + 5)

First: (2x) (5x) = 10x²

Outside: (2x) (5) = 10x

Inside:   (-7) (5x) = -35x

Last: (-7) (5) = -35

Add them all together, and you have the product:

   10x² + 10x -35x -35

Simplify the sum: 10x² - 25x -35

   or 5(x² - 5x - 7) .

How do i find the slope of a line that passes through a given point and is parallel or perpendicular to another given point?

Answers

There's no such thing as parallel or perpendicular "to a point". A problem like that
will always want the new line to be parallel or perpendicular to another line.

-- If the new line is parallel to the given line, then they have the same slope.

-- If the new line is perpendicular to the the given line, then the slope of the
new line is [ 1 / slope of the given line ].

In either case, you now have the slope of the new line and a point on it.
From there, you should have no trouble finding its equation.

Parallel is same slope.
Perpendicular is same slope but you have make it opposite and flip it.
For example if your slope is 2/3. For Perpendicular it would be - 3/2.

The value of y is 67 degrees when line segment BD is parallel to XY.

What is Coordinate Geometry?

A coordinate geometry is a branch of geometry where the position of the points on the plane is defined with the help of an ordered pair of numbers also known as coordinates.

The line segment BD is parallel to segment XY

We have to find the value of y

The angle 67 degrees and y are opposite to each other.

So the value of y is 67 degrees

The opposite angles are equal

The value of Y is 67 as angels that are opposite to each other are equal so the angle below Y is 67.

Knowing that we can say that Y is 67 as angels parallel to each other are also equal.

Hence, the value of y is 67 degrees when linesegment BD is parallel to XY.

in a swimming race, a student swam the first 50 meters in 42 seconds. she swam the secons 50 meters in 40 seconds. what was the students average speed during the race?

Answers

All you have to do is add 40 and 42 together and divide by 2. It's basically finding the mean.

One point on a line is given the coordinate 5.3. A second point on the line has a coordinate of 8.7.The distance between these points is __________ units.

Answers

Answer: The distance between these points is 5 units.

Step-by-step explanation:

We know that by Distance formula , the distance between two points (a,b) and (c,d) is given by :-

$D=√((d-b)^2+(c-a)^2)$

The given points = (5,3) and (8,7)

The distance between theses points will be :

$D=√((7-3)^2+(8-5)^2)\n\n\Rightarrow\ D=√((4)^2+(3)^2)\n\n\Rightarrow\ D=√(16+9)\n\n\Rightarrow\ D=√(25)=\pm5$

Since , Distance is always positive , it means the distance between the given points is 5 units.

Answer:

3.2

Step-by-step explanation:

The distance formula on a number line is

d= x2-x1

d= 8.7-5.3 =3.2
