Answer:

[tex]y=-\frac{2}{5}x-\frac{1}{5}[/tex]

Step-by-step explanation:

The equation of a line is y = mx + b

Where:

First, let's find what m is, the slope of the line.

Let's call the first point you gave, (-3,1), point #1, so the x and y numbers given will be called x1 and y1.

Also, let's call the second point you gave, (2,-1), point #2, so the x and y numbers here will be called x2 and y2.

Now, just plug the numbers into the formula for m above, like this:

[tex]m = -\frac{2}{5}[/tex]

So, we have the first piece to finding the equation of this line, and we can fill it into y=mx+b like this:

[tex]y=-\frac{2}{5}x + b[/tex]

Now, what about b, the y-intercept?

To find b, think about what your (x,y) points mean:

Now, look at our line's equation so far: [tex]y=-\frac{2}{5}x + b[/tex]. [tex]b[/tex] is what we want, the -[tex]-\frac{2}{5}[/tex] is already set and x and y are just two 'free variables' sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specfically passes through the two points (-3,1) and (2,-1).

So, why not plug in for x and y from one of our (x,y) points that we know the line passes through? This will allow us to solve for b for the particular line that passes through the two points you gave!

You can use either (x,y) point you want. The answer will be the same:

See! In both cases, we got the same value for b. And this completes our problem.

The equation of the line that passes through the points  (-3,1) and (2,-1) is [tex]y=-\frac{2}{5}x-\frac{1}{5}[/tex]

Answer:

The 7th term is 1856.

Step-by-step explanation:

The equation of this is n * 2 for the next of every variable. So with this knowledge,

first term = 29

Multiply by 2.

second term = 58

Multiply by 2.

third term = 116

Multiply by 2.

fourth term = 232

Multiply by 2.

fifth term = 464

Multiply by 2.

sixth term = 928

Multiply by 2.

seventh term = 1856.

rearrange them first add 48 to both sides of equations. simplify them 104 = 8y y=-13

Answer:

16.50

Step-by-step explanation:

The width of the TV will be equal to 16.49 inches.

Pythagorean theorem states that in the right angle triangle the hypotenuse square is equal to the square of the sum of the other two sides. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.

Pythagorean theorem states that in the right angle triangle the hypotenuse square is equal to the square of the sum of the other two sides.

Given that a certain television is advertised as a 21-inch TV (the diagonal length). If the height of the TV is 13 inches.

The width of the TV will be calculated as,

W = √ ( 21² - 13² )

W = √ ( 441 - 169 )

W = √272

W = 16.49 inches

Therefore, the width of the TV will be equal to 16.49 inches.

Answer:

Rectangle Perimeter = 26

Step-by-step explanation:

Rectangle ABCD , Length = parallel horizontal sides are AB & CD, Breadth = parallel vertical sides = BC & AD

AB segment joining A (0,0) - B (0,9) = 9 units. CD joining C (4, 9) & D (4,0) = 9 units. So, Length = 9 units

BC segment joining B (0,9) - C (4,9) = 4 units. AD joining A (0,0) - D (4,0) = 4 units. So, Breadth = 4 units

Perimeter of rectangle = 2 (Length + Breadth)

= 2 (9 + 4)

= 13 x 2 = 26

Answer:

Area of the figure = 171 in²

Step-by-step explanation:

Composite figure given in the picture comprises of three figures, two right triangles and one rectangle.

Area of the composite figure = Area of two right triangles + Area of the rectangle at the center

Area of one right triangle = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]

                                           = [tex]\frac{1}{2}(12)(9)[/tex]

                                           = 54 in²

Area of the rectangle = Length × Width

                                    = 7 × 9

                                    = 63 in²

Area of the composite figure = 2(54) + 63

                                                  = 108 + 63

                                                  = 171 in²

Answer: 7/18

Step-by-step explanation:

Number of customers at Eva's boutique = 90

Number of customers who wore a size extra-large = 35

The probability that a randomly selected customer wore a size extra-large will be:

= Number of customers who wore a size extra-large / Number of customers at Eva's boutique

= 35 / 90

= 7/18

Therefore, the probability that a randomly selected customer wore a size extra large is 7/18.

Answer:

See attachment :)

Step-by-step explanation:

The given equation is in slope-intercept form, which lists the slope and the y-intercept of the line.

Slope-intercept form is  [tex]y=mx+b[/tex], where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept. The y-intercept, 2, is a point on the y-axis where the line intersects with the axis. So, we can graph the given intercept on the y-axis, (0,2).

The slope, [tex]m[/tex], is [tex]\frac{4}{5}[/tex]. The slope is the rise of the line over the run, or [tex]\frac{rise}{run}[/tex]. For this equation, then, we rise 4 units and run 5.

We'll start from the y-intercept, a point we know will be on our line. From this point, move up 4 units, and right 5. A negative slope would run  to the left, but this is a positive line, so the run will go to the left. Now, we are on the point (5,6). From this point, we can repeat this [tex]\frac{rise}{run}[/tex].

A few of the following points are (10,10), (14,15), and (18,20). Now, draw a line connecting these points. This line is a graph of our equation.

There are 10 numbers who are perfect squares.

When an integer is multiplied by the same integer, the resultant number is known as a square number. For example, when we multiply 5 × 5 = 52, we get 25. Here, 25 is a square number. Square numbers are always positive, they cannot be negative because when a negative number is multiplied by the same negative number, it results in a positive number.

The properties of square numbers are listed below which helps to identify them easily.

Given:

2 and 140

Now, the perfect squares are:

√4=2

√9=3

√16 =4

√25=5

√36=6

√49=7

√64=8

√81=9

√100=10
