The slope is -1/5 after using the formula m=rise over run. Reflected across the x-axis, the slope is 1/5 because the y coordinates become negative when reflected across x-axis.
Descriptions 1, 2, 3, and 5 are accurate, though 5 is ambiguous.
_____
Description 4 goes with (7x)² = 49x², not 7x².
Description 6 goes with 5·8 + x² + (2x + 8) = x² +2x +48, not 40x² +100x +40.
The description for 5 is accurate, but could also be applied to y² + 3(y - 4), which is why it can be considered to be ambiguous. There are a number of ways to resolve the ambiguity, but they were not used here.
There would be 8 lines of symmetry for this shape.
Answer:
hh
Step-by-step explanation:
The missing percent is 70
7/10 times 10 is 70/100 which is 70 %
