Answer:
yes
Step-by-step explanation:
To determine if (1, 9) is a solution, substitute x = 1 into the right side of the equations and if the result is y = 9 then it is a solution
y = 1 + 8 = 9 ← True
y = 5(1) + 4 = 5 + 4 = 9 ← True
Thus (1, 9) is a solution to the system of equations.

Answer: 14</h3>
Explanation:
Pick two columns from the table to form the (x,y) points.
I'll pick the last two columns, since everything is positive here. So we have the points (2, 17) and (4, 45)
Apply the slope formula to those points
m = (y2 - y1)/(x2 - x1)
m = (45 - 17)/(4 - 2)
m = (28)/(2)
m = 14
The rate of change is 14.

Answer:
-105 ft
Step-by-step explanation:
His elevation after 5 minutes is -45 ft (-12*5)
= -45ft - 60ft
= -105 ft
