Answer:
Not sure if you mean 2x+y=-4 or 2x+y=4
either way put it in y=mx + b form (slope intercept)
Step-by-step explanation:
so for 2x+y = -4 first move everything away from the side with "y" by -2x from each side you get y= -2x+ -4 so m= -2/1 (slope) and b= -4 the place the line crosses the y axis
so for 2x+y = 4 first move everything away from the side with "y" by -2x from each side you get y= -2x+ 4 so m= -2/1 (slope) and b= 4 the place the line crosses the y axis
Answer:
the answer is 18.53.... hope this helps
Step-by-step explanation:
how you find the area of a circle is the radius times pi which pi is 3.14
The slope between the points (5,5) and (1, -2) is 7/4
A line parallel to to that would also be 7/4 (m = 7/4)
Use the Point-Slope formula to find k:
Let (6,6) = (x, y) and let (-3, k) = (x1, y1)
y - y1 = m(x - x1)
6 - k = (7/4)(-3 - 6)
6 - k = (7/4)(-9)
6 - k = -63/4
6 + 63/4 = k
24/4 + 63/4 = k
87/4 = k
Answer:
y = -2x + 2
Step-by-step explanation:
slope is found with (change in y/change in x), or in this case, (-4--2,3-2), which is -2
with the equation y = -2x + b, solve for b by plugging in the x and y values of one of the points
using (2, -2):
-2 = -2(2) +b
b = 2
so the equation is y = -2x + 2
To find present value from monthly payments, we use
P_A=A((1+i)^n-1)/(i(1+i)^n)
where
A=monthly payment = $821.69
i=monthly interest rate = 6.5%/12 = 0.065/12
n=number of months = 30*12 = 360
Therefore
Present value
= amount borrowed
=A((1+i)^n-1)/(i(1+i)^n)
=821.69*((1+0.065/12)^360-1)/((0.065/12)*(1+0.065/12)^360)
= 130000.25
(note: the 0.25 could well be a round off error because the monthly payment is only accurate to the cent)
