Solve the system: y = x + 2 , y = -3x + 10 . Answer as an ordered pair. (x,y)

(2,4)

Step-by-step explanation:

y = x + 2

y = -3x + 10

y = y

x + 2 = -3x + 10

x + 3x + 2 = 10

4x + 2 = 10

4x = 10 - 2

4x = 8

x = 8 ÷ 4

x = 2

y = x + 2

y = (2) + 2

y = 4

The probe starts at 16 feet above sea level then it is lowered 9.8 feet per minute.

Start at 16 and then subtract 9.8 times the number of minutes:

Depth = 16 - 9.8m

Now to find the depth after 90 minutes replace m with 90 and solve:

Depth = 16-9.8(90)

Depth = 16 - 882

Depth = -866 feet
