Answer:
10nCr6 over 6nCr3
Step-by-step explanation:
this should give you the answer
Now, for the equation that we're trying to find, all that they give us is their slope, and a point that it passes through. How do we get the slope? Perpendicular line's slopes are negative reciprocals of each other. This means that you flip the coefficient of the x around, and multiply it by negative 1. So, we see that the given slope of the other line is -4/5. That means, we flip it around (-5/4), them multiply it by -1, which means the slope of our new line is 5/4. Now, we have the x, but what do we do with the point? We plug it into the point-slope formula
y-y1=m(x-x1) , where m = slope, and (x1,y1)
Our slope (m) is 5/4, our x1 is 4, and our y2 is 12 (these are the points given to us in the original problem, (4,12).)
Now, we plug it in, then get y by itself
y-y1=m(x-x1)
y-(12)=(5/4)(x-4)
y-12=5/4(x-4)
y=5/4(x-4)+12
y=5/4x-5+12
y=5/4x+7
So, our new equation is
y=5/4x+7
Answer:
To find average, please add all the numbers together:
4.2+...+2.25=17.25
Now, divide by 5, the number of terms:
17.25/5=3.45
<h2><u>Problem</u>:-</h2>
3.) If y varies directly as x and y = 24 when x = 6, find the variation constant and the equation of variation.
<h2><u>Solution</u>:-</h2>
A. Express the statement “y varies directly as x”, as y = kx .
B. Solve for k by substituting the given values in the equation.
<h2><u>Answer</u>:-</h2>
- Therefore, the constant of variation is 4.
C. Form the equation of the variation by substituting 4 in the statement y = kx. Thus , <u>y = 4 x.</u>
