12/4 = 3 + 2x 1/2
Divide and then multiply and your answer will be 4
Answer:
Step-by-step explanation:
f * g = (x^2 + 3x - 4) (x+4)
open bracket
x((x^2 + 3x - 4) + 4 (x^2 + 3x - 4)
x³ +3x²-4x+x²+12x-16
x³+3x²+x²-4x+12x-16
x³+4x²+8x-16 (domain is all real numbers.
f/g = (x^2 + 3x - 4)/(x+4)
factorising (x^2 + 3x - 4)
x²+4x-x_4
x(x+4) -1 (x+4)
(x+4)(x-1)
f/g = (x^2 + 3x - 4)/(x+4) =(x+4)(x-1)/(x+4) = (x-1)
Before factorisation, this was a rational function so the domain is all real numbers excluding any value that would make the denominator equal zero.
Hence I got x - 1, and x cannot equal -4
So the domain is just all real numbers without -4
Answer:
12
Step-by-step explanation:
Simplify \frac{4}{5}G
5
4
G to \frac{4G}{5}
5
4G
.
\frac{4G}{5}+42=2.8G+18
5
4G
+42=2.8G+18
Multiply both sides by 5.
4g + 210 = 14g + 90
Simplify
14G + 90 - 4G to 10G + 90
Subtract 90 from both sides.
210-90=10G210−90=10G
Simplify 210-90210−90 to 120120.
120=10G120=10G
Divide both sides by 1010.
\frac{120}{10}=G
10
120
=G
Simplify \frac{120}{10}
10
120
to 1212.
12=G12=G
Switch sides.
G=12G=12

Answer:
Here, x represents the amount of time that the money is accruing interest.
Step-by-step explanation:
The function below represents the annual interest Alexander earns on a savings account.
f(x) = 500(1 +0.02)x
Here, x represents the amount of time that the money is accruing interest.
We know that, if R% of interest is accrued over a principal of P over time , T,
then the net interest accrued is given by,
P×R×T/100
