Answer:

35

Step-by-step explanation:

Since repetition is allowed, we use the equation

((n+r-1)!/(r!(n-1)!) = 7!/(3!x4!) = 35

2x-3y=0 in slope intercept form, show all steps please!
Ierofanga [76]

In <em>slope-intercept form</em>, the <em>y</em> is isolated or

by itself on the left side of the equation.

Start by subtracting 2x from both sides and we have -3y = -2x.

Then we divide both sides by -3 to get <em>y = 2/3x</em>.

Work is provided in the image below.

Find the common difference of the arithmetic sequence. 6,9.4,12.8,16.2
Blababa [14]

A sequence is said to be arithmetic if every couple of adjacent elements differ by the same number. If this is the case, that constant number is called the common difference.

This sequence is arithmetic, because the difference between every element and the previous one is

  • 9.4 - 6 = 3.4
  • 12.8 - 9.4 = 3.4
  • 16.2 - 12.8 = 3.4

So, the common differnece is 3.4, because every couple of adjacent terms differ by 3.4
