Answer:
y = 2 when x =12
Step-by-step explanation:
y = k/x ..............as y varies inversely as x
8 = k/3
k = 8 * 3
k = 24
So,
y = k/x
y = 24/12
y = 2
Answer: Slope is m = 2/3
Step-by-step explanation:
-You have exactly four points on a table:

-Use the slope formula and use any two points from those four points in order to find the slope:

-The two points I use are
and
for the equation:

Answer:
Hello!!
the point (6, 7) is reflected across the y axis. what are the coordinates of the reflection?
(-6, 7)
Step by Step Explanation:
When reflecting (x, y) over the x axis is (x, -y)
When reflecting (x, y) over the y axis is (-x, y)
Hope this helps!
Answer:
y = 13
Step-by-step explanation:
Calculate the distance d using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (- 2, 7) and (x₂, y₂ ) = (6, y)
d =
, that is
d =
= 10
= 10 ← square both sides
64 + (y - 7)² = 100 ( subtract 64 from both sides )
(y - 7)² = 36 ← take the square root of both sides
y - 7 = 6 ( add 7 to both sides )
y = 13
