Answer:
B. (15, 19)
Step-by-step explanation:
To check to see if a particular ordered pair is a solution to an equation, use the values for the variables and see if the equation is true.
A. 4/5(0) +7 = 7 ≠ 1
B. 4/5(15) +7 = 19 . . . . . . is a solution
C. 4/5(-5) +7 = 3 ≠ 11
D. 4/5(-2) +7 = 27/5 ≠ 1

A calculator can help with this.
14 < n - 3
We must isolate n. To do that we must bring -3 to the left side of the equation. To make -3 zero on the right side of the equation and bring it to the left side you must add 3 to both sides like so...
14 + 3 < n + (-3 + 3)
17 < n + 0
17 < n
Hope this helped!

Answer:
8.6 is the answer
Step-by-step explanation:
A = (3,9)
B = (8,2)
d² = (8-3)² + (2-9)²
or, d² = 5² + (-7)²
or, d² = 25 + 49
or, d² = 74
d = 8.6
