The segment was only rotated, not changed. It would be the same length as the original.
To find the length, use the distance formula.
(5, 8) would be point 1.
(-6,8) would be point 2.
Plug them into the formula.
Simplify.
Square root this answer.
Negative distances aren't possible, so your answer is 11.
Hope this helped!

Answer:
(x+10)/2
Step-by-step explanation:
interchange the variables x and y
x=2y-10
solve for y
y=x+10/2
Answer:
x = 2
y = -3
Step-by-step explanation:
Step 1: Write systems of equation
8x + 7y = -5
x = -3y - 7
Step 2: Solve for <em>y</em>
- Substitute 2nd equation into 1st: 8(-3y - 7) + 7y = -5
- Distribute 8: -24y - 56 + 7y = -5
- Combine like terms: -17y - 56 = -5
- Add 56 to both sides: -17y = 51
- Divide both sides by -17: y = -3
Step 3: Solve for <em>x</em>
- Substitute <em>y</em> to find <em>x</em>: x = -3(-3) - 7
- Multiply: x = 9 - 7
- Subtract: x = 2
Step 4: Check
<em>Plug in x, y into an original equation to verify it's a solution.</em>
2 = -3(-3) - 7
2 = 9 - 7
2 = 2
Answer:
c
Step-by-step explanation:
a: 9/5 and 19/10 are already in simplest form
b:25/35 can be simplified to 5/7 if you divide each side by 5 and 20/24 can
be simplified to 5/6 if you divide each side by 4
c: both 15/10 and 21/14 can be simplified to 3/2
d: 4/6=2/3 and 10/16=5/8
