Answer:
I know for sure that it is 1.5, -1.5
A)
Accurate = close to the 'true' value, and 9.998 is close to 10. Imagine a scale that has the zero point wrong as says 8.998, it would not be accurate, but still precise (several digits known)
Precise = several digits known. I would say to know it until grams is quite a good precision (the 9.998 has 4 digits)
Answer:
B
Step-by-step explanation:
Combine like term.
Hers 7x and (-5x) are like terms
7x + 4x² - 5x = 7x - 5x + 4x²
= 2x + 4x²

Answer:
see below
Step-by-step explanation:
When a figure is rotated about a center point, the central angle formed by any point on the figure and the corresponding image point will be the rotation angle. Every image point is the same distance from the center of rotation that the pre-image point was. No lengths or angles are changed: rotation is a "rigid motion", so the rotated figure is congruent with the original.

-Angle AQA' is 60 degrees.
-Triangles ABC and A'B'C' are congruent.
-Angle ABC is congruent to angle A'B'C'. (<em>this is one of the angles of the congruent triangles</em>)
-Segment BC is congruent to segment B'C'
-Segment AQ is congruent to segment A'Q.
First of all z=16 and its true
