7: The point B (-8,5) is dilated from the origin with a scale factor of 12 . What are the coordinates of B'? A (−6,3) B (−4,2.5
1 answer:
Answer:
The correct option is option B.
The coordinate of B' is (-4,2.5).
Step-by-step explanation:
Formula of dilation:
Image = (pre-image)×(scale factor)
Scale factor:
The amount by which the shrinks or grows is called " scale factor".
- If the scale factor less than 1 then the shape shrinks.
- If the sale factor equal to 1 then the shape remains same.
- If the scale factor greater than 1 then the shape enlarged.
Given point is B(-8,5)
Scale factor is .
The co-ordinate of image B is
=(-4,2.5)
The coordinate of B' is (-4,2.5).

Step-by-step explanation:
Jane is given a $100 gift to start and saves $35 a month from her allowance.
- After 1 month, Jane has saved
- After 2 months, Jane has saved
- After three months, Jane has saved
- and so on
In general, after x months Jane has saved
This means that it makes sense to represent the relationship between the amount saved and the number of months with one constant rate (in this case the constant rate is 35). It makes sense because the amount of money increases by $35 each month. Since the amount of increase is constant, we get constant rate. Also the initial amount is known ($100), so there is a possibility to write the equation of linear function representing this situation.
