Answer:
<h3>
R(-1, -9)</h3>
Step-by-step explanation:
When we reflect over x-axis then the x-coordinate doesn't change and the y-coordinate changes its sign
in means if R = (x, y) then R' = (x, -y)
so we have:
x = -1 and -y = 9
y = -9
which gives R = (-1, -9)
Steps to solve:
y + 8 = -11
~Subtract 8 to both sides
y = -19
Best of Luck!
Answer:
igneous
Step-by-step explanation:
Igneous rocks are formed from lava or magma. Magma is molten rock that is underground and lava is molten rock that erupts out on the surface. The two main types of igneous rocks are plutonic rocks and volcanic rocks. Plutonic rocks are formed when magma cools and solidifies underground.
Answer:
5.39 units
Step-by-step explanation:
Pythagorean theorem: 
Let point (-2,1) be C
Line segment AC would be 2 units long.
Line segment BC would be 5 units long.
Insert the length of the line segments in to the Pythagorean theorem
4 + 25 = 29
≅ 5.385
