Answer:
Answer: 16.16
Step-by-step explanation:
xy in this situation, will be the distance between the two points.
(-8,2) (7,-4) Find the distance between the points
To ind the distance, find the difference in the x and y values,square them and add them to find the obtained number square root.
2-(-4) = 6
-8 - 7 = -15
6^2 + (-15)^2 = d^2 where d is the distance
36 + 225 = d^2
261 = d^2
d=
d= 16.1554 rounded to the nearest hundredth is 16.16
Answer:
x = - 6
Step-by-step explanation:
Given
x + 5 = 1 ( subtract 5 from both sides )
x = - 4
Multiply both sides by 3 to clear the fraction
2x = - 12 ( divide both sides by 2 )
x = - 6
