write the point-slope equation of the line that passes through(3,5) and (7,1)

Answers

Answer:   y - 1 = –(x –7)

or   y –5 = –1(x –3)

The attachment shows the graph of these equations (identical)

Step-by-step explanation:

The basic form for a point-slope equation is

y - b = m(x - a)

a is the x-value from the given coordinate,  b is the y-value form the given coordinate,  m is the slope. x and y are the variables in the function.

To find the slope, m, use the given coordinates. Get the difference in the y-values and divide by the difference in the x-values. This is "rise over run."

Subtract the first coordinate from the second coordinate.

Given coordinate points: ​(3​,5) and ​(7​,1)    substitute values:

m= 1 –5 / 7 –3  becomes  m= –4/4   so the slope, m = –4/4

That is –1  The "1" is "understood," so only the negative sign represents the slope  in the equation

To write the equation:  Take the basic form, substitute b and a values from either given coordinate. And use the value of m we just calculated.

y - b = m(x - a)  Using the second coordinate: (7,1)

y - 1 = –(x –7)

or using the first coordinate:

y –5 = –(x –3)

What is a Square?

Square in geometry is a special kind of rectangle with four equal sides and four right (90°) angles.

Given is a square playground has an area of 400 square feet.

Area of square playground = 400 ft².

Area of square is given by square of the length of its sides. If 'a' is the side of a square, then mathematically we can write -

A [S] = a²

Using the formula discussed above -

a² = 400

a = √400

a = 20 ft

Therefore, the length of each side of the playground is 20 ft.

Step-by-step explanation:

The following data were obtained from the question:

6×10⁹/ 3×10⁴ =?

The above expression can be simplified as follow:

6×10⁹/ 3×10⁴ = 6×10⁹ ÷ 3×10⁴

Recall:

Aᵐ ÷ Aⁿ = Aᵐ ¯ ⁿ

Therefore,

6×10⁹ ÷ 3×10⁴ = (6/3) × 10⁹ ¯ ⁴

6×10⁹ ÷ 3×10⁴ = 2 × 10⁵

Thus, 6×10⁹/ 3×10⁴ is equal to 2 × 10⁵

Answers

Answer:

Step-by-step explanation:

If a boat has the speed = 15 miles per hour

Let the speed of the river = v miles per hour

If the boat is moving down stream, that means boat is traveling with the stream of the river.

So the speed of the boat downstream = (15 + v) miles per hour

Since, speed of the river stream is added with the speed of the boat, it will reach the destination earlier than the expectation.

Find equation of the line shown

Answers

Answer:

y = x + 6

Step-by-step explanation:

y = mx + b

Since (0,6) is your y-intercept (or just positive 6), you have your b part of the equation solved.

The line goes up at a continuous rate of up 1, over 1, so they cancel each other out, making the m part of your equation 1.

So, you have y = 1x + 6 and you change it to just y = x + 6 (since x itself automatically has a 1 before it, when it's by itself).

Find the measure of the exterior angle.

Answers

Answer:

120 degrees

Step-by-step explanation:

Because the triangle is a right triangle, it can be either a 45,45,90 triangle or a 30,60,90 triangle. I tested this problem with each scenerio, and I believe that it is a 30, 60, 90 triangle, with the top angle being 30 degrees, thus, making x=30. For the exterior angle, we'd multiply 4 by 30 to get 120 degrees.

I checked my answer by adding 120 to 60 (that's the degrees of the right hand corner of the triangle), which added to 180 degrees (aka a flat line), which verifies my answer.

The difference of two numbers is 16. The greater number is 5 less than 4 times the smaller
number. Find the two numbers.

Answers

Answer:

x= 23

y=7

Step-by-step explanation:

x-y=16

4y-5=x

4y-5-y=16

3y-5=16 add 5 to both sides

3y=21 divide by 3 on both sides

y=7

x-7=16 substitute back in

x=23 added 7 to both sides

so x=23 and y=7

23-7=16

Let x = smaller number
Let y = greater number
Then we have that y = 4x − 5y − x = 16
Replace the value of y in the second equation you get 4x − 5 − x = 16
3x − 5 = 16
3x = 21
x = 7

y = 23

The solution of the equation as x= -1 then y= -1 and x= 3 then y = 7.

What is Equation?

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

We have equations y = -x²+4 and y = 2x+1.

So, 2x + 1 = -x²+4

x² - 4 -2x +1 = 0

x²-2x -3 = 0

Now splitting the mid term we get

x²-2x -3 = 0

x²-3x +x -3 = 0

x(x-3 ) + 1 (x-3)= 0

(x+ 1) (x-3) = 0

x= -1 or 3.

and, when x= -1 then y= -1

when x= 3 then y = 7.
