d. True
Step-by-step explanation:
It represents a proportional and linear relationship.
It costs $9.75 for each ticket.
<u>x² + 3x + 3 = 0</u>
I can tell by looking that there's no easy way to factor the left side,
so we'll have to use the Quadratic formula.
Before doing that, let's just take a look at the discriminant:
( B² - 4AC ) = (9) - (4 x 3 x 1) = (9 - 12) = -3 .
The discriminant is negative, so we know that the roots will be complex conjugates.
Again: <u>x² + 3x + 3 = 0</u>
x = (1/2) [ -3 plus or minus the square root of (-3) ]
<u>x = -3/2 + (1/2) j√3</u>
and
<u>x = - 3/2 - (1/2) j√3</u>
Answer:
Step-by-step explanation:
Value of the car at the end of the first year = £9680
Depreciation = 12 %
Original price = £ x
If we reduce 12% of original price from x, we will get £9680
x - 12% of x = £ 9680

Original price = £ 11000
0.1
the 0 is in the thousandths place plus the 2 os next to is since 2<5 it is 0
q>-1
Step-by-step explanation:
q-12>-13
or, q>-13+12
q>-1
