Answer:
(x, y) = (-6, 3)
Step-by-step explanation:
Maybe you want to solve ...
- y = -2x -9
- 2x +3y = -3
Use the first equation to substitute for y in the second:
2x +3(-2x -9) = -3
2x -6x -27 = -3
-4x = 24 . . . . . . . . . add 27, simplify
x = -6 . . . . . . . . . . . divide by -4
y = -2(-6) -9 = 12 -9 = 3
The solution is (x, y) = (-6, 3).
Answer:
72.033 ft
Step-by-step explanation:
To find this, let us set up a fraction. Since 18.47 = 1 second, y = is 3.9 seconds. Let "y" be the variable.
Step 1: Switch sides
Step 2: Apply rule:
Step 3: Multiply both sides by
Step 4: Simplify
The bear can run 72.033 feet in 3.9 seconds
