Answer:
x = 1.5
Step-by-step explanation:
Since the axis of symmetry is between the 2 x intercepts, we can find it by finding the average of the x-coordinates of the 2 points.
(-7 + 10) / 2
3/2
= 1.5
So, the axis of symmetry is at x = 1.5
Answer:
The amount of interest payable after 6 months is $28.
Step-by-step explanation:
Here, the Principal amount borrowed = $400
Rate of Interest = 14%
Time = 6 months = 6 / 12 years = 0.5 year
Now, SIMPLE INTEREST = 
So, here SI = 
or, SI = $28
Hence, the amount of interest payable after 6 months is $28.
Squaring a number means you're multiplying the number by itself. This would mean (6b)^2 = (6b)(6b).
