Answer:
5
Step-by-step explanation:
Put -6 where x is and do the arithmetic.

To solve this we need to use this formula:
a(b+c)=ab+ac
5(7+3x)-12=35+15x-12=15x+23
Answer:
x = 6
y = -2
Step-by-step explanation:
6 - 8 = -2
2 x 6 = 12 - 14 = -2
Answers are like this: 1)Cos C 2)Cos B 3)Cos A 4)a 5)b 6)c all of them are different type of writing cosines law , just this.
Answer:
input: x+4 output (x,y)
-2 -2 + 4 =2 2 (-2,2)
0 0 + 4 = 4 4 (0,4)
2 2 + 4 = 6 6 (2,6)
...
Step-by-step explanation:
continue by plugging in x to the equation, x is input and y is output
then just plot your (x,y) points on the graph.
