Answer:
x3, +1
Step-by-step explanation:
To go from x to 3x +1, we need to multiply by 3 and add 1. However, the order is important! Think back to PEMDAS, BIDMAS or any equivalent, we know that multiplication goes before addition, and so x3 happens first. To double check, let's have a look at an example, and use x = 2, and so 3x+1 becomes 7.
If we add first, we get 2+1 = 3, and then when we multiply, we get 3x3=9, which isn't correct.
If we multiply first, we get 3x2=6, and then 6+1=7

Answer:
<h3>A (3, 1)</h3>
Step-by-step explanation:
If we have the coordinate (x,y), if this coordinate is rotated by 180 degrees clockwise, the resulting coordinate will be expressed as (-x, -y) i.e the original coordinate axis are both negated.
Given the coordinate C(-3, -1), if this coordinate is rotated clockwise about the origin, the coordinate of the resulting point will be at C' (-(-3), -(-1))
C' (-(-3), -(-1))
C' = (3, 1)
Hence option A is correct
Answer:
x = 1
Step-by-step explanation:
Sum the coefficients of the polynomial, that is
1 - 6 + 11 - 6 = 0
Hence x = 1 is a root and (x - 1) is a factor of the polynomial
