Answer:
A
Step-by-step explanation:
Given
x² - 25 = 0 ( add 25 to both sides )
x² = 25 ( take the square root of both sides )
x = ± 
= ± 5
Solutions are x = 5 and x = - 5
Answer:
9. 4x<12
10. x (greater than or equal to) 6
11. 9x>36
12. x (greater than or equal to) -5
13. x>15
14. x (less than or equal to) -30
15. x>-48
16. x<1
Step-by-step explanation:
i hope this helps :)
As the focus is at (0,5) it will be symmetrical about the y axis and will open upwards
General formula is x^2 = 4ay where a is the y coordinate of the focus
So its y = x^2/5*4
y = 1/20 x^2
The tax is found by mult. the total purchase by 1.07:
1.07(3)($0.99) = $3.18 (rounded up to the nearest cent)
