The answer your looking for well be A
Answer:
It is slope of a line which is 4
Step-by-step explanation:
We are given that the given points are generated by a linear function. A linear function is ta straight line that can be represented by:
Here m is the slope
The slope of a line is given by the formula:
In order to find the slope from the table we take any two pairs of inputs and outputs i.e. x and y
So here we take
(x1,y1) = (-6,-16)
(x2,y2) = (-5,-12)
Putting the values in the formula
Hence,
It is slope of a line which is 4
Answer: 13
Step-by-step explanation: Pythagorean theorem,
a²+b²=c²
5²+12²=c²
25+144=c²
Square root of 169 is 13

18 + 81 = 9(x²<span> + 6x + 9)

When we are completing the square, we are going to move the value of c across the equals. We will do that by adding, and end up with
18=9(x²+6x)
We take the value of b (the coefficient of x), divide it by 2 and square it:
(6/2)²=3²=9
This is the value that completes the square. However, since the entire square is multiplied by 9, this value must be multiplied by 9 before we can add it across the equals:
18+9(9) = 9(x²+6x+9)
18+81=9(x²+6x+9)
99=9(x²+6x+9)
Dividing both sides by 9, we have:
11=x²+6x+9
11=(x+3)²
