Answer:
(f - g)(x) = 9x + 1
Step-by-step explanation:
Step 1: Write out functions
f(x) = 3x + 10x = 13x
g(x) = 4x - 1
Step 2: Find (f - g)(x)
(f - g)(x) = 13x - (4x - 1)
(f - g)(x) = 13x - 4x + 1
(f - g)(x) = 9x + 1
X=lebgth
y=width.
I suggest this system of equations:
x=2y
(x+4)(y+4) - xy=88
we can solve this system by substitution method.
(2y+4)(y+4)-2y(y)=88
2y²+8y+4y+16-2y²=88
12y=88-16
12y=72
y=72/12
y=6
x=2y
x=2(6)=12
Answer: the dimensions of the original rectangle are:
length=12 m
width=6 m
Answer:
a) interest in 30 years will be $1,890
b) account balance in 30 years will be $6,390
Step-by-step explanation:
Interest = Principal · Rate · Time

= 1,890
Total Amount = Interest + Principal
= 1,890 + 4,500
