Answer:
Logarithms cannot have non-positive arguments (which are negative or zero), but quadratics and other equations can have negative solutions.
I hope that helped
Answer:
See solution below
Step-by-step explanation:
The following are the rules for counter clockwise rotation of a point around the origin. Let's assume the coordinates of the original point are A(x, y). The following are results of different degrees of rotation(all counterclockwise) for the new point A'
<u>Original Point A</u> <u> Degree of Rotation</u> <u>Coordinates of A'</u>
A(x, y) 90° A'(-y, x)
A(x, y) 180° A'(-x, -y)
A(x, y) 270° A'(y, -x)
In these questions we are only interested in 270° counterclockwise rotation where the resultant point A' has its original x, y coordinates swapped and x is made negative. A, B represent the originals, A', B' etc the post image coordinates ie the answers
<u>Q1 </u>
A (4, 7) →→ A' (7, -4)
B (3, 0) →→ B' (0, -3)
C (-4, -7) →→ C' (-7, 4)
<u>Q3</u>
A (3, 0) →→ A' (0, -3)
B (7, 0) →→ B' (0, -7)
C (3, -5) →→ C' (-5, -3)
D (-2, -5) →→ D' (-5, 2)
Answer:
B
Step-by-step explanation:
Surveying 30 7th graders would give biased results, because 4 seventh graders are running for class president, meaning that 7th graders would be more likely to vote for their fellow classmates who are running
