Point slope form is y-y1=m(x-x1)
M is the slope
y1 and x1 come from the point given
Answer:
Y+8=1/2(x-0)
If it should be simplified y+8=1/2x
The x value is 0 because when the line intercepts the y axis x=0
Am assuming the text of the problem is:
"At 6:00 p.m., the temperature was 55 Fahrenheit. At 11:00 p.m. that same evening, the temperature was 40 Fahrenheit. What real number represents the average change in temperature per hour?"
Average change in temperature per hour = (55 - 40)/(11 - 6)
Average change in temperature per hour = 15/5
Average change in temperature per hour = 3 Fahrenheit per hour
P = $3,471.52, the principal
r = 3.1% = 0.031, annual ratr
n = 12, monthly compounding
t = 21 years
Note that n*t = 252.
The value after 21 years is
A = 3471.52*(1 + 0.031/12)²⁵²
= $6,650.91
The interest earned is
6650.91 - 3471.52 = 3179.39
Answer: $3,179.39
Answer:
The are parallel lines.
Step-by-step explanation:
2x + 3y = 4
3y = -2x + 4
y = -2/3x + 4/3
10x + 15y = 2
15y = - 10x + 2
y = -10/15x + 2/15
y = - 2/3x + 2/15
Answer: D. $3,450
Given: 2,500 shares of a stock bought for $8 a share
<span>Probabilities: the stock will rise to a value of $32 a share is 22%</span> <span> the stock will fall to $3 a share is 78%</span>
<span>Question: What is the expected value of the investor’s profit from buying the stock?</span>
Solution: (22%(32-8)-78%(8-3))2500
(.22(24)-.78(5))2500
(5.28-3.9)2500
(1.38)2500
3450
