Answer:
The answers A, B, and C all work for this problem. The answer D is the only one that does not.
Step-by-step explanation:
When looking at two parenthesis being multiplied together and being equal to 0, we know that at least one of the parenthesis must be equal to 0 for it to be true. In A and C, the first parenthesis will be equal to 0 due to a = -6.
(a + 6)
(-6 + 6)
(0)
And in B, we can see that the second parenthesis would be equal to 0 due to b = 1
(b - 1)
(1 - 1)
(0)
Now we can try the D options, but will note that they do not work for either parenthesis.
(a + 6)(b - 1)
(0 + 6)(0 - 1)
(6)(-1)
Answer:
x = 17.046
y = 17.045
Step-by-step explanation:
neclace price = x
bracelet price = y
35+75=110
35 = 31.82% of 110 ($596.625)
75 = 68.18% of 110 ($1,278.375)
Answer:
x=7,-17/3
Step-by-step explanation:
It will take an additional 8 weeks to reach a height of 48 centimeters.
y = 4.5x
Since, the maximum height is 48 cm and the plant has already grown 12 cm, we deduct the 12 from 48 to get the additional weeks it needs to grow.
48 - 12 = 4.5x
36 = 4.5x
36/4.5 = 4.5x / 4.5
x = 8 weeks.
1. 6.25 x 10^0
2. 8.07 x 10^-1
