Answer:
$30
Step-by-step explanation:
Multiply 15 by 2 because 4 hours is twice as much as 2 hours.
Solution:
y = 2x^2 - 3 ---- equation 1
y = 3x - 1 ------equation 2
Then we get,
2x^2 - 3 = 3x - 1
Now, simplifying the equation, we get
2x^2 - 3x - 3 + 1 = 0
2x^2 - 3x - 2 = 0
After factoring the equation, we get
(2x+1)(x-2) = 0
So, this means
(2x+1) = 0 and (x-2) = 0
From this, we get
x = -1/2 and x = 2
Putting values of x = -1/2 in equation 2
y = 3(-1/2) - 1
y = -2.5
Now, putting value of x = 2 in equation 2
y = 3(2) -1
y = 5
Answer:
4 or 5
Step-by-step explanation:
The answer is $122.13
Explanation:
610 • 0.32 = 1,105.6
Then you’re going to add everything up:
650 + 260.40 + 260.40 + 16.95 + 11.56 + 10.56 + 17.84
And get =
1,227.73
And you’re going to subtract that with 1,105.6 and get the answer.
