Answer:
Explanation:
<em>The line y = -1 </em>is horizontal: parallel to the y-axis.
The point<em> B (2,3)</em> is above <em>the line y = - 1 </em>at a distance equal to the y-coordinate of B (y = 3) less - 1:
When the <em>point B (2,3) </em>is <em>reflected over the line y = -1</em>, the x-coordinate does not change. The image will be 4 units down the line y = -1, thus the y-coordinate will be - 1 - 4 = - 5.
Hence,<em> the coordinates of the vertex B'</em> are x = 2, y = - 5: (2, - 5).
The last one is a function. A rule for functions is that there can only be one x value or coordinate but there can be multiple y values or coordinates.
The sum of an infiinte series exists when the ratio is in the interval (-1,1)
Here the ratio is 1/3, then the sum exists.
The formula for this sum is A / (1 -r); where A is the first term and r is the ratio
Then, the sum is [1/3] / [1 -1/3] = [1/3] / [2/3] = 1/2
Answer: 1/2
Answer:
b = -18
Step-by-step explanation:
Multiply both sides by -6/1 which is the reciprocal of -1/6
(-6/1)*(-1/6)b=3*(-6/1)
b=-18/1 = -18
1 step: Divide the polynomial 
by the polynomial 
with remainder:
Here 
is quotient and 
is remainder.
2 step: Substitute previous result into the fraction:
Answer: correct choice is A.
