The answer is A. sin40=6/x
Answer:
Convex, since none of the angles are greater than 180°
Answer:
Step-by-step explanation:
-3x -7 +2x + 9 = 5
-x + 2 = 5 (you are combining like terms here)
-x = 3
x = -3
Hope this helps :)
The value of the function at x = -1 is 5
<h3>What is function?</h3>
Function can be defined as an expression, rule, or law that defines a relationship between one variable known as the independent variable and another called the dependent variable.
From the information given, we have that;
f (x) = 3 (2)x with x=-1
Now, let's substitute the value of x as - 1 in the function given;
f (x) = 3 (2)x
f (x) = 3 (2) -1
Expand the bracket;
f (x) = 6 - 1
f(x) = 5
Thus, the value of the function at x = -1 is 5
