Answer:
C. c = 10
Step-by-step explanation:
You have to use the Pythagorean theorem:
c² = 6² + 8²
c² = 36 + 64
c² = 100
c = √100
c = 10
(11,11). The first coordinate in a pair is the x coordinate, which tells you how far to move left of right. The second coordinate is the y coordinate, which tells you how much to move up or down. If you’re translating right, you’re going to add to the first number. If you’re translating left, you would subtract it. If you’re translating up, you add to the second number. If you’re translating down, you subtract from the second coordinate.
Work only with the second equation at the beginning. Solve for x for it.
7x - 2x = 3 Combine the left hand side.
5x = 3 Divide by 5
5x/5 = 3/5 Do the division
x = 3/5 = 0.6
==============
Now work with the top equation.
3(0.6) + 5y = 13 Multiply on the left.
1.8 + 5y = 13 Subtract 1.8 from both sides.
1.8 - 1.8 + 5y = 13 - 1.8 Do the subtraction
5y = 11.2 Divide by 5
5y/5 = 11.2/5
y = 2.24 Answer
La raíz cuadrada de 35 creo que es 5
Answer:
Step-by-step explanation:
Use the formula of distance between the two points 
and 
,
Distance = 
1. Distance between A(3, 4) and B(8, 12),
AB = 
AB = 
= 
≈ 9.43
2. Distance between C(-2, 10) and D(3, -2),
CD = 
= 
= 
= 13.00
3. Distance between X(20, 4) and Y(17, 0),
XY = 
= 
= 
= 5.00
4. Distance between E(2, -1) and M(6, 9),
EM = 
= 
= 
= 10.77
