Answer: y = 6 - 4x
Step-by-step explanation: Find the slope: (y2-y1) / (x2-x1). In this case, [2-(-6)] / (-1-1) = 8/-2 = -4. Then write it in intercept form, substituting in a point for y and x: 2 = a -4(-1). Then balance to get a = 6. So y = 6 - 4x
We know that
the formula of the <span>the sum of the arithmetic sequence is
Sum=n*(a1+an)/2
n=36
a1=3
a36=?
find a36
an=a1+(n-1)*d
for n=2 a2=9
9=3+(2-1)*d----> 9=3+d----> d=6
so
for n=36
a36=a1+(36-1)*6----> a36=3+35*6----> a36=213
</span>Sum=n*(a1+an)/2-----> 36*[3+213]/2----> 3888
the answer is
3888
First, let's review the formula for the "sum of two cubes:"
a^3 + b^3 = (a + b)(a^2 - ab + b^2).
Unfortunately, 9 is not a perfect cube. The cube root of 9 is 9^(1/3), and the square of the cube root of 9 is therefore 9^(2/3).
Thus,
9x^3 + 64 = (9^(1/3)*x + 4) * (9^(2/3)x^2 - 4*9^(1/3) + 16)
Answer:
11
Step-by-step explanation:
The median is the middle value when all of the numbers are put in order from smallest to largest
6, 7, 10, 11,13,13,15
There are seven numbers so the middle number is 4
(3 on the left and 3 on the right)
The median is 11
