Answer:
The domain of the function is 0 less-than-or-equal-to x less-than infinity ⇒ 3rd answer
Step-by-step explanation:
The domain of the function f(x) = y is all the values of x which make the function defined
∵ 
- There is no square root for negative number, that means x
must be non-negative number
∵ The non negative numbers start from zero till infinity
∴ 0 ≤ x < ∞
∴ x must be greater than or equal zero and less than infinity
- Values of x are the domain of the function
∴ The domain of the function is 0 ≤ x < ∞
The domain of the function is 0 less-than-or-equal-to x less-than infinity
Answer:
True
Step-by-step explanation:
3x5=15
15+8=23
23=23
I don't think It is 72,
most likely, its 21....?
(also sorry for before, lol)
Answer:
The graph and the number line in the attached figure
Step-by-step explanation:
we have
Solve for x
subtract 7 both sides
Divide by -2 both sides
Remember
When you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol
so
The solution is the interval (-8,∞)
All real numbers greater than -8
In a number line the solution is the shaded area at right of x=-8 (open circle)
The graph and the number line in the attached figure
To start, let's define our variable, which is x. x will represent the width of the rectangle. Next, since you know that the length is 4 times as long as the width, it will be represented by 4x. Now, since you know that the perimeter of a figure is the sum of the length of all the sides of the rectangle, you can express the perimeter with this expression: 4x+4x+x+x
Then, you set the expression to the perimeter, which is 110.
4x+4x+x+x=110
Combine like terms: 10x=110
And solve for x: x=11
Now that you have solved for x, which represents the width of the rectangle, you now know that your answer is 11.
