Step-by-step explanation:
log(z) is defined when z > 0.
For log(9 - x²) to be defined, we have 9 - x² > 0.
=> x² < 9, -3 < x < 3.
The domain of y = log(9 - x²) is (-3,3).
first work out the value of 2 bags of chips which is: 0.75 + 0.75 = 1.50p
take that away from the total: 22.50-1.50=21 pounds
since what is left (21) is how much 4 ham sandwiches cost we can just divide 21 by 4 which is 5.25
so each sandwich costs 5.25 pounds
Answer:
x^2 = 9
Step-by-step explanation:
Both 3 and -3 are 9 when squared.
Answer:
(1, 0 )
Step-by-step explanation:
A translation of 5 units left means subtract 5 from the x- coordinate
A translation of 1 unit down means subtract 1 from the y- coordinate, thus
(6, 1 ) → (6 - 5, 1 - 1 ) → (1, 0 )
