Distance formula: d= square root of (x2-x1)^2+(y2-y1)^2
(3,5) (7,3)
d= square root of (7-3)^2+(3-5)^2
d= square root of (4^2)+(-2^2)
d= square root of 16+4
d= square root of 20
d=4.47...rounded= 4.5
Hope this helped!
Y varies equal to 26.. going to multiple the x varies that mean 2*14=x28 to find y subtract 28 from y-2 varies equal y=26
X^2+x-20
x^2+5x-4x-20
x(x+5)-4(x+5)
(x-4)(x+5)
1/7 has an infinitely repeating decimal block of .142857 as its decimal expansion.
1/7 = .142857142857 ...
The repeating block has 6 digits in it. Note that the 7th digit of 1/7 is 1 which is the first digit of the repeating block.
To get the 2015th digit, divide 2015 by 6 and focus on the remainder.
2015/6 = 335 with a remainder of 5.
The 2015th digit of 1/7 will be the fifth digit of the repeating block 142857 which just happens to be 5.
Answer: 5
To find the slop:e of two points (x¹, y¹) and (x², y²)
In the case of our points (5, -3) and (5, 7)...
Since you cannot divide by zero, the slope of these points (or any vertical line) is considered to be <em>
undefined.</em>
