Answer:
[tex]y= \frac{3}{2}x+\frac{9}{2}[/tex]
Step-by-step explanation:
First find the slope: [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} } = \frac{-3 - (3)}{-5-(-1)} = \frac{-6}{-4} = \frac{3}{2}[/tex]
Next use the point-slope fomula and one of the points to find the line:
[tex]y-y_{1} =m(x-x_{1} )[/tex] and the ordered pair (-1,3)
[tex]y-3=\frac{3}{2}(x-(-1))\\ y-3 = \frac{3}{2}(x+1)\\y-3=\frac{3}{2}x + \frac{3}{2}\\y=\frac{3}{2}x +\frac{3}{2}+3\\y = \frac{3}{2}x + \frac{9}{2}[/tex]

what is the distance formula?
Answer:
Distance formula. The formula for distance, if you know time (duration) and the average speed, is: d = v x t. where v is the velocity (average speed), t is the time and d is distance, so you can read it as Distance = Speed x Time. The result will depend on the unit of the speed metric, for example if speed is given in mph,
Step-by-step explanation:
A (m 1 ,n 1) and B (m 2 ,n 2) are the coordinates of the two given points in the coordinate plane.
The distance between the two points can be calculated using the distance formula, d = √ (m2 - m1)2 + (n2 - n1)2
Finally, express the given solution in proper units.
A small bar of gold measures 20 mm by 250 mm by 2 mm. One cubic millimeter of gold weighs about 0.0005 ounces. Find the volume in cubic millimeters and the weight in ounces of this small bar of gold.
Answer: v = 40mm * 25mm * 2mm = 2000 mm^3 so, the weight is 2000 mm^3 * .0005oz/1mm^3 = 1oz

Which is the completely factored form of 4x2 28x 49? (x 7)(4x 7) 4(x 7)(x 7) (2x 7)(2x 7) 2(x 7)(x 7)
The completely factored form of 4x^2 + 28x + 49 is given by: Option C: (2x+7)(2x+7)
How to find the factors of a quadratic expression?If the given quadratic expression is of the form ax^2 + bx + c, then its factored form is obtained by two numbers alpha( α ) and beta( β) such that:
[tex]b = \alpha + \beta \\ ac =\alpha \times \beta[/tex]
Then writing b in terms of alpha and beta would help us getting common factors out.
Sometimes, it is not possible to find factors easily, so using the quadratic equation formula can help out without any trial and error.
For this case, the given quadratic expression is:
[tex]4x^2 + 28x + 49[/tex]
So we've to find two numbers such that:
Their sum = b = 28
Their product = [tex]ac = 4\times 49 = 196[/tex]
We can see that 196 is square of 14, and that 14 added twice forms 28, thus:
14 + 14 = 28
14×14 = 196
Writing b = 28 as sum of 14 twice, we get:
[tex]4x^2 + 28x + 49 = 4x^2 + 14x + 14x +49 \\4x^2 + 28x + 49 = 2x(2x+7) + 7(2x + 7)\\4x^2 + 28x + 49 = (2x+7)(2x+7)[/tex]
Thus, the completely factored form of 4x^2 + 28x + 49 is given by: Option C: (2x+7)(2x+7)

help! which expression is equivalent to 14x + 35 - 21 y
Answer:
7(2x + 5 - 3y)
Step-by-step explanation:
Looking at the Factors below the question, what do you notice?
I notice that 14, 35 and 21 all have a GCF of 7
With this, we can now start factoring, but before we start, keep in mind that we need to find terms that when multiplied with 7 give us 14x, 35, and -21y.
Be careful with the signs ( + and -) when factoring!14x + 35 - 21y
7(2x + 5 - 3y)
Check you answer to make sure if results in our original expression:
7(2x + 5 - 3y) <== distribute seven
7(2x) + 7(5) + 7(-3y)
14x + 35 - 21y
Therefore, we have correctly factored the expression, and the correct answer is 7(2x + 5 - 3y)

A bicycle wheel travels 321 in for each revolution. What is the radius of the wheel
Answer:
51.1 ≈ r
Step-by-step explanation:
"A bicycle wheel travels 321 in for each revolution"- means that 321 is the circumference of the wheel that is a circle.
C = 2· π· r
What is the radius of the wheel ?
321 = 2· π· r, divide both sides of the equation by 2 π
(321/2·π) = r , use calculator, solve and round the answer
