Try drawing a picture! To reflect something over the x-axis just change the sign of the y coordinates.

Use the point-slope form to write an equation of a line through the given points.
Luden [163]

Answer:

y-2=1/3(x+3)

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(4-2)/(3-(-3))

m=2/(3+3)

m=2/6

simplify

m=1/3

y-y1=m(x-x1)

y-2=1/3(x-(-3))

y-2=1/3(x+3)

Which set of measurements forms a right triangle? Use the Pythagorean theorem: a2 + b2 = c2.
user100 [1]

Answer:

A. 15, 20, 25.

Step-by-step explanation:

25^2 = 625

20^2 = 400

15^2 = 225.

Now 625 = 400 + 225 = 625 so it is choice A.

B is the midpoint of segment AC trying to find AB using the definition of midpoint.
Kipish [7]

Answer:

12

Step-by-step explanation:

A midpoint of a line means that each segment connecting from the midpoint to an end is equal. For this problem, this means that AB = BC, as B is the midpoint, and A and B are the ends. Therefore, we can say that:

AB = BC

2x + 6 = 5x - 3

add 3 to both sides

2x + 9 = 5x

subtract 2x from both sides

9 = 3x

divide both sides by 3

3 = x

Plugging 3=x into AB, this means that 2(3) + 6 = AB = 12
