Answer:
Option (D)
Step-by-step explanation:
Standard equation of a quadratic function is,
ax² + bx + c
Comparing this function with the given quadratic function,
f(x) = 2x² - 4x - 3
a = 2, b = -4 and c = -3
By using quadratic formula to get the value of x,
x =
=
=
=
=
Therefore, Susie made a mistake in step IV.
Option (D) is the answer.
The number in the middle of 2.3 and 9.5 is calculated by finding the average, which is done by adding the two numbers and dividing the sum by 2, resulting in 5.9.
To find the number in the middle of 2.3 and 9.5, we need to calculate the average (or the mean) of the two numbers. This can be done by adding the two numbers together and then dividing by 2.
The calculation steps are as follows:
Therefore, the number in the middle of 2.3 and 9.5 is 5.9.

Answer:
After 12.86 days Nick and Perry will have the same amount of money
Step-by-step explanation:
Perrie's can be expressed as;
Total amount Perry will have after t days=Initial amount Perry has-Total amount Perry spends
where;
Initial amount that Perry has=$180
Total amount Perry spends=Amount he spends per day×Number of days=(6×t)=6t
Replacing in the expression;
Total amount Perry will have after t days=(180-6t)
Nick's can be expressed as;
Total amount Nick will have after t days=Initial amount Perry has+Total amount Nick earns
where;
Initial amount that Nick has=$0
Total amount Nick earns=Amount he earns per day×Number of days=(8×t)=8t
Replacing in the expression;
Total amount Nick will have after t days=(0-8t)=8t
Equating Total amount Nick will have after t days to Total amount Perry will have after t days;
180-6t=8t
180=(8t+6t)
14t=180
t=(180/14)=12.86 days
After 12.86 days Nick and Perry will have the same amount of money
