Its because 20 is doubling its self. Its using 100% of its number, While 40 is decreasing by 50%. Half of forty is 20. Half equals 50%.
Answer:
<u>2 1/6x +10</u>
Step-by-step explanation:
All you need to do is combine like terms.
3/2x+<u>4</u>+2/3x+<u>6</u>
3/2x+<u>10</u>+2/3x
<u>3/2x + 2/3x</u>= <u>2 1/6x</u>
<u>2 1/6x+10</u>
Answer:
<u>XZ is longer than XY</u>
Step-by-step explanation:
First we can notice all of the answers consist of knowing the lengths, so we must now find the lengths for each segment. To do this, we must use the pythagorean theorem.
(1, -1) and (-5, -5)
-5- -1 = -4
-5-1 = -6
-4^2+-6^2 = c^2
16+36 = c^2
52 = c^2
7.21110255 = c
So, the length of XZ is 7.21110255 units long
(1, -1) and (8, -2)
8-1 = 7
-2--1 = -1
7^2+-1^2 = c^2
49+1 = c^2
50 = c^2
7.07106781 = c
So, the length of XY is 7.07106781 units long.
<u>XZ is longer than XY</u>
2 because it is the number being added to the zero intercept in the equation
