Answer: x = 5
Step-by-step explanation:
We can set up an equation to solve for x:
3x + 4 = 19
We can subtract 4 from both sides:
3x = 15
We can divide both sides by 3:
x = 5
7−4x+3=x−16−3x
Simplify
7−4x+3=x−16−3x
7+−4x+3=x+−16+−3x
(−4x)+(7+3)=(x+−3x)+(−16)(Combine Like Terms)
−4x+10=−2x+−16
−4x+10=−2x−16
Add 2x to both sides.
−4x+10+2x=−2x−16+2x
−2x+10=−16
Subtract 10 from both sides.
−2x+10−10=−16−10
−2x=−26
Divide both sides by -2.
−2x/−2=−26/−2
x=13

Answer:
-4f
Step-by-step explanation:
Hi! Let's work on simplifying this.
f(4) = 4f
f(0) = 0, because anything x 0 is 0
f(-8) = -8f
Our equation is 4f + -8f
We can get rid of the plus negative...
4f - 8f
So we get:
-4f
Answer:
The principal investment required to get a total amount, principal plus interest, of $400.00 from simple interest at a rate of 8% per year for 9 years is $232.56.
Step-by-step explanation:
Given
- Total accrued Amount A = 400.00 (Let say $)
- Interest rate r = 8% = 0.08
To determine
Principle P = ?
Using the formula
P = A / (1 + rt)
substituting A = 400.00, t = 9 and r = 0.08 in the formula
P = 400 / ( 1 + (0.08 × 9))
P = $232.56
Therefore, the principal investment required to get a total amount, principal plus interest, of $400.00 from simple interest at a rate of 8% per year for 9 years is $232.56.
