Answer:
y=-4x-24
Step-by-step explanation:
The equation of a line is always in the form y=mx+c. By subbing in the values given by the two points, we get:
0=-6m+c
-24=c
∴0=-6m-24
6m=-24
m=-4
∴the equation is: y=-4x-24
Answer:
3 7/12
Step-by-step explanation:
1/2 of a mile.
Step-by-step explanation:
He has already gone 4/8 of a mile (3/8 + 1/8) and he needs to go 8/8 of a mile. 8/8 - 4/8 = 4/8. You can simplify that to 1/2.
Answer:
142 years 3 months
Step-by-step explanation:
Let us assume the investment is made using a simple interest
Given data
Principal p= $1200
Rate r= 7.5%= 7.5/100= 0.075
Final amount A= $14000
Time t=?
The Simple interest formula is expressed as
A= p(1+rt)
Substituting we can solve for t
14000= 1200(1+0.075t)
14000= 1200+90t
14000-1200=90t
12800= 90t
t= 12800/90t = 142.22 years
The time required to get a total amount, principal plus interest, of $14,000.00 from simple interest on a principal of $1,200.00 at an interest rate of 7.5% per year is 142.22 years (about 142 years 3 months).
Answer:
(2,5)
Step-by-step explanation:
y= 4x-3
y=-2x+9
-------------------------
4x-3=-2x+9
6x-3=9
6x=12
x=2
-----------------
y = 4(2)-3
y =8 -3
y=5
(2,5)
