Find The Equation Of The Linepassing Through The Points (3,1)and (7,-7).y = [? ]x + []

Answers

Answer 1

Given:

A line passes through two points are (3,1) and (7,-7).

To find:

The equation of the line.

Solution:

The line passes through two points are (3,1) and (7,-7). So, the equation of line is

[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

[tex]y-1=\dfrac{-7-1}{7-3}(x-3)[/tex]

[tex]y-1=\dfrac{-8}{4}(x-3)[/tex]

[tex]y-1=-2(x-3)[/tex]

Using distributive property, we get

[tex]y-1=-2(x)-2(-3)[/tex]

[tex]y-1=-2x+6[/tex]

Adding 1 on both sides, we get

[tex]y=-2x+6+1[/tex]

[tex]y=-2x+7[/tex]

Therefore, the equation of line is [tex]y=-2x+7[/tex]. So, the missing values are -2 and 7 respectively.

The length of one side of a shoebox is 8 centimeters more than twice the width. The base of the shoebox has an area of 72 square centimeter.
Write an equation to represent this situation with w representing the width in centimeter

Answers

Answer:  [tex]w^2+4w-36=0[/tex]

Step-by-step explanation:

Let w = width of the base of the shoebox.

As per given ,

Length = 8+2w centimeters

Area of base = 72 square centimeter

Area of rectangle =  Length x width

[tex]\Rightarrow\ 72=w(2w+8)\\\\\Rightarrow\ 72= 2w^2+8w\\\\\Rightarrow\ 2w^2+8w-72=0\\\\\Rightarrow\ w^2+4w-36=0[/tex]

=> The sum of the measures of interior angles of triangle add up to 180 degrees.

So,

3x + 3x + 3x = 180

9x = 180

Divide both sides by 9

x = 20

Given right triangle ABC with altitude BD drawn to hypotenuse AC. If AD=3 and DC=12, what is the length of BD?

Answers

Answer:

The answers is 8.06on DeltaMath

Step-by-step explanation:

The length of BD which is the altitude of the right angle triangle will be 6 units.

What is a right-angle triangle?

It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.

According to the hypotenuse-leg (HL) principle, a right triangle is harmonious if each of its third side and legs are congruent with its equivalent hypotenuse and legs in another right triangle. The HL theorem proves that these triangles are identical.

A right triangle ABC with altitude BD drawn to hypotenuse AC. If AD = 3 and DC = 12.

Then the equation is given as,

BD² = AD x DC

BD² = 3 x 12

BD² = 36

BD = 6

The length of BD which is the altitude of the right angle triangle will be 6 units.

Ellie took a taxi from her house to the airport. The taxi company charged a pick-up fee of $1.50 plus $5 per mile. The total fare was $76,50, not including the tip. Write and solve an equation which can be used to determine m, the number of miles in the taxi ride.


I dont understand this​

Answers

Answer:   1.50+5m=76.50 m=15

Step-by-step explanation:

The required equation is 1.5 + 5m = 76.50 and distance travelled is 15 miles.

What is an equation?

In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .

Now it is given that,

pick-up fee = $1.50 plus $5 per mile

Since, m is the number of miles in the taxi ride

So, equation for pick-up fee for m miles,

pick-up fee = $1.50 + $5m

Now total fare = $76,50

Thus, required equation to determine m is given as,

1.50 + 5m = 76.50

Subtracting 1.5 both the side we get,

1.50 + 5m - 1.5 = 76.50 - 1.5

⇒ 5m = 75

or, m = 75/5

⇒ m = 15

Thus, the required equation is 1.5 + 5m = 76.50 and distance travelled is 15 miles.
