Answer:
![\sqrt{5}\ units](https://tex.z-dn.net/?f=%5Csqrt%7B5%7D%5C%20units)
Step-by-step explanation:
we know that
The rule of the translation is equal to
![(x,y)-----> (x+2,y+1)](https://tex.z-dn.net/?f=%28x%2Cy%29-----%3E%20%28x%2B2%2Cy%2B1%29)
That means
The translations is
units to the right and
unit up
Let
-------> the coordinates of point B
------> the coordinates of point B'
Find the distance
the formula to calculate the distance between two points is equal to
![d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%28y2-y1%29%5E%7B2%7D%2B%28x2-x1%29%5E%7B2%7D%7D)
substitute
![d=\sqrt{((y+1)-y)^{2}+((x+2)-x)^{2}}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%28%28y%2B1%29-y%29%5E%7B2%7D%2B%28%28x%2B2%29-x%29%5E%7B2%7D%7D)
![d=\sqrt{(1)^{2}+(2)^{2}}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%281%29%5E%7B2%7D%2B%282%29%5E%7B2%7D%7D)
![d=\sqrt{5}\ units](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B5%7D%5C%20units)
Answer:
x^2=5-x
x^2+x-5=0
x=-1± √(1)^2-4(1)(-5) /2(1)
-1± √21 /2
Step-by-step explanation:
Answer:
the distributive property of 18+42 is multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.
