3x-2-(2x+1)= 3x-2-2x-1
= x- 3
C. x - 3
Answer:
The equation is -3x^2 + 30x + 225 = 0, and the number of days is 15.
Step-by-step explanation:
I assume an x is missing, and the function is h(x) = -3x^2 + 30x + 225
You want to know the number of days in which the function value is zero.
-3x^2 + 30x + 225 = 0
Divide both sides by -3.
x^2 - 10x - 75 = 0
(x - 15)(x + 5) = 0
x - 15 = 0 or x + 5 = 0
x = 15 or x = -5
We discard the negative solution.
Answer: The equation is -3x^2 + 30x + 225 = 0, and the number of days is 15.
Answer: 4x + 76 = 688, $153 per ticket
Step-by-step explanation:
there are 4 tickets but you don't know the price of the tickets. Let x represent the price. Insurance costs $19. They got insurance ($19) on all 4 tickets (19 x 4) to get a insurance total of $76.
To get the price of one ticket we need to solve the equation.
4x + 76 = 688
subtract 76 from both sides.
4x = 612
divide by 4.
x = 153
each ticket costs $153
Tan is opposite/adjacent.
Tan=8/6
Tan=simplified to 4/3
So you answer is C.

Answer:
$70,750
Step-by-step explanation:
The expected gain/loss is found by <em>adding the products of all of the profits/losses by their probability</em>. So,
<em>(0.8 * 100000) + (0.1 * 0) + (0.1 * -2500)</em> =
<em>80000 + 0 + -250</em> =
$70750
