Answer:
Distance is 8.485
Midpoint is (3,4)
Step-by-step explanation:
Use the points (-1,7) and (5,1)
Insert them into the equation and solve for D
![D=\sqrt{x} ((5-(-1))^2 + (1-7)^2)\\D=\sqrt{x} ((6)^2 + (-6)^2)\\D=\sqrt{x} (36+36)\\D=\sqrt{x} (72)\\D=8.485](https://tex.z-dn.net/?f=D%3D%5Csqrt%7Bx%7D%20%28%285-%28-1%29%29%5E2%20%2B%20%281-7%29%5E2%29%5C%5CD%3D%5Csqrt%7Bx%7D%20%28%286%29%5E2%20%2B%20%28-6%29%5E2%29%5C%5CD%3D%5Csqrt%7Bx%7D%20%2836%2B36%29%5C%5CD%3D%5Csqrt%7Bx%7D%20%2872%29%5C%5CD%3D8.485)
Insert points into second equation to find midpoint
![(\frac{_1+5}{2} , \frac{7+1}{2}) \\(\frac{6}{2} ,\frac{8}{2} )\\(3,4)](https://tex.z-dn.net/?f=%28%5Cfrac%7B_1%2B5%7D%7B2%7D%20%2C%20%5Cfrac%7B7%2B1%7D%7B2%7D%29%20%5C%5C%28%5Cfrac%7B6%7D%7B2%7D%20%2C%5Cfrac%7B8%7D%7B2%7D%20%29%5C%5C%283%2C4%29)
Step-by-step explanation:
Dilation changes the size of the shape and is not a rigid motion.
Answer:
The correct answer is x= 4/5 because you cannot take the root of a negative number
9514 1404 393
Answer:
see below
Step-by-step explanation:
Multiply the numbers as though they were integers, then mark off a number of decimal places in the product equal to the total number of decimal places in the numbers being multiplied (1).
Some fractions that are equivalent to 2/3 are 4/6 and 6/9
to find equivalent fractions, you just have to reduce the fraction or multiply both the top and bottom numbers by the same number to increase the fraction.
2/3 is as reduced as it can be, though.
