What is the equation of the line that passes through the point (-3, 1) and has a slope of - 2

Mathematics

Yakvenalex [24]2 years ago
8 0

Step-by-step explanation:

slope = (y2-y1) / (x2-x1)

equation of the line y2 - y1 = m(x2-x1),

y2 = m(x2-x1) +y1

y2-y1 = -2(x2- (-3))

y2-y1 = -2x -6

y2 - 1 = -2x -6

y2 = -2x -5

1. Suppose you take a coin and flip it 4 times in a row. After each flip you record whether the coin landed heads or tails. What
bekas [8.4K]

Answer:

25%

Step-by-step explanation:

Great question, since a regular coin has two sides one heads and one tails. That gives us a 50% probability of it landing on either side of the coin. Since we would like to know the probability of getting 2 heads in a row, we would need to multiply the probability of the first toss landing on heads with the second toss landing on heads, like so...

\frac{1}{2} *\frac{1}{2} =\frac{1}{4}

So we can see that the probability of us getting two heads in a row is that of \frac{1}{4}[/tex] or 25%.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

If m and n are positive integers such that the greatest common factor of <img src="https://tex.z-dn.net/?f=%20m%5E%7B2%7D%20n%5E
torisob [31]
The greatest common factor of m^{2}  n^{2} and m n^{3}

is
 
gcd(m*m*n*n, m*n*n*n) =m*n*n=m n^{2}

what we did, was to see how many m's and how many n's, each expression have, and then pick the smallest of each letter (factor).

the reason is that the common factor, must have enough m's and n's to divide the m's and n's of both expressions

so
45=m n^{2}
also 
45=5*9=5*3^{2}

thus, n is equal to 3

X = 22 + 10x<br> How to find x?
GrogVix [38]

Answer:

x = -2.44

Step-by-step explanation:

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract 10x from both sides:

x (-10x) = 22 + 10x (-10x)

x - 10x = 22

-9x = 22

Isolate the variable, x. Divide -9 from both sides:

(-9x)/-9 = (22)/-9

x = 22/-9

x = -(22/9)

x = -2.44 (repeating).

x = -2.44 (rounded) is your answer.
