Tanα=5/12
α=arctan(5/12)°
α≈22.62° (to nearest hundredth of a degree)
Answer:
first box is 4/5 and the second box (=) is 7/15
Remember that a parallel line has the same slope...
So we already know the slope of the line containing point C is -4.
Using point slope equation, we can do...
y-y₁=m(x-x₁)
y-7= -4(x-4)
y-7- -4x+16
*Add seven to both sides...* y=-4x+23
There is you answer... hope this helps!
Answer:
(-2, 1)
Step-by-step explanation:
Hi Juliadayx! How are you?
Well, maybe you already heard about the domain and the range of a function.
The domain is the set of values that the independent variable can take (usually referred to as the letter "x"), while the range is the set of values that the dependent variable takes, which is called f(x) or function of x.
In this case, the exercise asks you to evaluate for which values of “x” (right column of the table), the function “f(x)” takes positive values (left column of the table), the positive values also include zero. And in this case you can see that the function f(x) is only positive for the values of "x": -2, -1, 0 and 1. Therefore, the answer is the entire interval (-2, 1).
I hope I've been helpful!
Regards!

Step-by-step explanation:
13:
It is a function, notice that if you draw a vertical line anywhere, it doesn't pass two points.
Domain : All real numbers (x-values)
Range : 2 (y-values)
14:
Not a function, if you draw a vertical line through one point, it will hit two others.
Domain : -3
Range : 4 , 0, -4
15:
It is a function, no two points in any vertical line.
Domain: All real numbers
Range: All real numbers
16:
Not a function, two points in one line
Domain : -5 ≤ x ≤ 5
Range: -2 ≤ y ≤ 2
