For this, combine like terms. In this case, the like terms are 3x-2x, 2y+3y, and (-5). Combine them, and your answer will be 
Area of a square = Length ^2
480 = (x+4)^2
√480 = x + 4
21.9 = x + 4
x = 17.9
The difference in ' x ' (left or right) between D and F is 5 units.
The difference in ' y ' (up or down) between D and F is 2 units.
The straight-line distance between them is
√ (5² + 2²)
= √ (25 + 4)
= √ (29)
= 5.3851.....
or 5.4 (rounded to the nearest tenth)
Answer:
Yes, it is a real number.
Step-by-step explanation:
All numbers are real numbers.
The rule for the translation is like a function. If X=2 and Y=-1, we just substitute those values in the rule of (x,y) => (x-1, y+3)
(2,-1)=>(1, 2) are the new coordinates. You went 1 to the left on the X axis and 3 up on the Y axis.
