Answer:
All real numbers
Step-by-step explanation:
The domain of the function represented by f(x) = x + 1 is the all real numbers as there is only addition involved in the function so putting any number as input will not lead the function to infinity.
Answer:
(-1, -2)
Step-by-step explanation:
4x - 7y = 10
3x + 2y = -7
The common multiple of the x coefficient is 12.
Multiple 3 to 4 to get 12; 4 to 3 to 12:
3(4x - 7y = 10)
4(3x + 2y = -7)
12x - 21y = 30
12x + 8y = -28
Subtract the two equations:
-29y = 58
y = -2
Substitute y = -2 to either 4x - 7y = 10 or 3x + 2y = -7. Typically, do the easier equation to solve:
3x + 2(-2) = -7
3x - 4 = -7
3x = -3
x = -1
The order pair solution is like a coordinate: (x, y)

Answer:
58.6*14=820.4 miles
Step-by-step explanation:
Answer:
x < − 4
Step-by-step explanation:
Divide both sides by 88.
1 − x > 40/8
Simplify 40/8 to 5.
1 - x > 51 − x > 5
Subtract 11 from both sides.
− x > 5 − 1
Simplify 5 - 15 − 1 to 44.
Multiply both sides by - 1 − 1.
x < − 4
