Your answer is A look at the Z coordinates x value
Part A: The algebraic equation for the situation is 2x - 3 = 5
Part B: Bob has 4 brand new music CD's
Step-by-step explanation:
Translate the situation into an algebraic equation:
- Ann has 5 brand new music CD’s, which is 3 less than twice the amount that Bob (x) has
- Find the value of x (the number of brand new CD's Bob has)
Part A:
∵ Bob has x brand new CD's
∵ Ann has 5 brand new music CD’s, which is 3 less than twice
the amount that Bob has
- That means multiply x by 2 and then subtract 3 from the product
and equate the answer by 5
∵ Twice x 2x
∵ 3 less than twice x = 2x - 3
∴ 2x - 3 = 5
The algebraic equation for the situation is 2x - 3 = 5
Part B:
Let us solve the equation to find the value of x
∵ 2x - 3 = 5
- Add 3 to both sides
∴ 2x = 8
- Divide both sides by 2
∴ x = 4
Bob has 4 brand new music CD's

Answer:
The value of an exterior angle is the sum of the two interior angles not adjacent to it so
a:
x = 64 + 45 = 
b:
3x + 6 = 153 so
3x = 147 so
x = 
Answer:
True if reflection over a line.
Step-by-step explanation:
Given that there is a reflection symmetry. We have to discuss about the quality of the design.
By reflection , we mean it can be either on a line or on a point.
If symmetry is on a line, then we get a mirror image of the original one keeping the line of symmetry as mirror. Hence in this case when rotated about axis of symmetry lying it its plane the original design would be maintained.
Examples are : Circles, ellipses, hyperbolas, etc.
Reflection about a point is obtained by keeping equal distance form the point.
For example, reflection of (1,1) over origin would be (-1,-1)
Here the rotation quality may not apply
