Answer:
Step-by-step explanation:
The formula for simple interest is
I = Prt
where I is the interest earned, P is the initial deposit, r is the rate in decimal form, and t is the time in years. For us,
I = 125(.03)(3) which gives us an interest amount of
I = 11.25
To find out how much money she has total after that interest builds up, we add that interest amount to the initial investement amount to get
125 + 11.25 = 136.25
One positive plus another is always positive because:
+ and + is +
+ and - is -
- and - is +
Answer:
put a dot on -5 on the y axis
Step-by-step explanation:
-1/3x-4/3y=2
1/3x-2/3y=4
First realize that the coefficient of x is -1/3 and 1/3 which can be eliminated with addition
Adding the two equations together gets
-6/3y=6
Simplify
-2y=6
y=-3
Substitute back into original equation
1/3x-2/3(-3)=4
1/3x+2=4
1/3x=2
x=6
Answer
x=6, y=-3
Check answer
-1/3(6)-4/3(-3) =?= 2
-2+4=2
2=2
Done!
Answer:
4x+12
Step-by-step explanation:
(x+2)+(x+2)=2x+4
(x+4)+(x+4)=2x+8
(2x+4)+(2x+8)=4x+12
