Answer:
- ∞ < x < ∞
Step-by-step explanation:
The domain of a quadratic function is all real values of x , that is
- ∞ < x < ∞
You have defined x to be the smaller of two consecutive integers. Then the larger will be (x+1). The given relation is
... (x) + 3(x+1) = -5 . . . . the smaller plus 3 times the larger is -5
... 4x + 3 = -5 . . . . . . . .simplify
... 4x = -8 . . . . . . . . . . subtract 3
... x = -2 . . . . . . . . . . . divide by the coefficient of x
The smaller of the two integers is -2.
Answer:
-9
Step-by-step explanation:
Given
See attachment for number line
Required
What does the arrow integer
Represent the value of the arrow with x.
The arrow is on number -9.
This number is what the arrow represents.
Hence:
Answer:
Step-by-step explanation:
7. Let the price of book be x
:- 8x + 17 = 129
8x = 129 - 17
8x = 112
x = 112/8
x = $14
Each book cost $14
8. Let the number of hours be x
9x + 15 = 87
9x = 87 - 15
9x = 72
x = 72/9
x = 8hrs
He paid for 8hours
9. Let the numbers be x, x +2, x +4,
So. x + x + 2 + x + 4 = 168
3x + 6 = 168
3x = 168 - 6
3x = 162
x = 162/3
x = 54
The smallest number is 54
10. Let the number of books be x
So, x/2 + 6 = 18
x/2 = 18 - 6
x/2 = 12
x = 12 ×2
x = 24
So she has 24 book's before
