-4+(-2)=
Adding negative numbers

-6

Step-by-step explanation:

-4 + (-2)

recall that;

- * - = +

- * + = -

+ * - = -

+ * + = +

So when we expand we'll have

-4 ( + * -) *2

-4 - 2 = -6

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
