The formula for simple interest =
I = PRT
P = initial capital = $7000
R = rate = 0.02 in this case
T = time = our variable we are solving for
Thus substitute the parts into the equation we get
280 = 7000*0.02*T
Solving for T we get A or 2 years
Answer:
77777
Step-by-step explanation:
we can look at the trend line, find the slope.
let's start at the start of the line, (0, 5).
the line goes up 5 units and goes right 1 unit, so that means the slope is 5/1, or 5.
so you know the slope is 5x. now let's see the y-intercept, ask yourself this, where is the start of the line ? we already answered that: (0, 5). so the y-intercept is 5.
the equation should look like y = 5x + 5, so the answer is C
0.0765 = 7.65 x 10^-2
965,000,000,000,000 = 9.65 x 10^14
8.61×10−8 = 0.0000000861
-3x-y = -17
-x+y=-1
Using addition
-4x +0y = -16
-4x=-16
x=4
Then plug the value of x into one of the original equations
-x+y=-7
-(4)+y=-7
y=-7+4
y=-3
The solution is x=4 and y=-3
Thus (4,-3)
