Answer:
Step-by-step explanation:
4(8+2n) = 4 + 4n
32 + 8n = 4+4n
4n = -28
n = -7
Answer:
1310.4
Step-by-step explanation:
26 x 12= 312 x 4.2= 1310.4
Answer:
Step-by-step explanation:
we know that
The simple interest formula is equal to
where
I is the Final Interest Value
P is the Principal amount of money to be invested
r is the rate of interest
t is Number of Time Periods
in this problem we have
substitute in the formula above
Solve for t
Convert to percent form
EQUATION 1) 2x - 3y = -4
EQUATION 2) 7x + 9y =- 5
Multiply the whole first equation by 3 so that we could find the values of X first.
1) 3(2x - 3y = -4)
1) 6x-9y=-12
2) 7x+9y=-5
Add the 2 equations together.
13x=-17
x=-17/3 OR -5 2/3
2x-3y=-4
Plug the value of X into the equation.
2(-17/3) -3y=-4
-11 1/3 - 3y=-4
-3y=-4+11 1/3
-3y=22/3
y=-22/9 OR -2 4/9

Answer:
(-4, 24)
(-2, 18)
(0, 12)
(2, 6)
(4, 0)
Step-by-step explanation:
You need to plug the domain values into the function for x to find the range, which is the y.
f(x) = 12-3x
So for -4, it would be f(-4) = 12 - 3(-4) = 24, and do the same with the other values.
