The sum of three consecutive odd numbers is 93. What is the smallest of three numbers ?
Julli [10]

Answer:

Step-by-step explanation: it doesn't matter if it says even or odd it's the same formula

Because think if you start with 1 to get 3 you add 2

If you start with 2 to get the next even number you add 2

So it's X+ (X+2)+ (X+4)=93

X is the first # X+2 is the next # X+4 is the 3rd number if you want to check add the numbers to make sure they add up to 93

The smallest of course is X

Sonbull [250]

Answer:

The answer is below

Step-by-step explanation:

When you refer to a normal vector you mean the form a*x + b*y + c*z = d, if that's the case then it's not unique in the nose because it gives you its normal vector. Taking into account that uniqueness only supports multiplicative constants, which means that you can multiply the equation with whatever you want, that is, it remains the same

What is the slope of the line that passes through the points (4, 9) and (1, 6)?
Aleksandr [31]

a = ( 1 , 6 )

b = ( 4 , 9 )

slope =  \frac{y(b) - y(a)}{x(b) - x(a)} \\

Now just need to put the coordinates in the above equation :

slope =  \frac{9 - 6}{4 - 1} \\

slope =  \frac{3}{3} \\

slope = 1

And we're done...♥️♥️♥️♥️♥️
