Distribute the three

3(4x^2 + 1)

12x^3 + 3

he weight of a chimpanzee, y, in pounds, x months after birth is modeled by the equation y=1.5x+8. Which represents the equation

soldi70 [24.7K]

The equation that represents x when solved is $x=\frac{y-8}{1.5}$

Given the equation that expresses the weight of a chimpanzee with respect to the months of birth as:

y = 1.5x + 8

We are to express x in terms of "y"

$y = 1.5x + 8$

Subtract 8 from both sides

$y -8= 1.5x + 8-8\\y-8 = 1.5x\\Swap\\1.5x = y - 8$

Divide both sides by 1.5

$\frac{1.x}{1.5}= \frac{y-8}{1.5} \\x=\frac{y-8}{1.5} \\$

Hence the equation that represents x when solved is $x=\frac{y-8}{1.5}$

What lump sum must be invested at 9%, compounded monthly, for the investment to grow to $72,000 in 6 years?

lana [24]

Answer: $42042.50

Step-by-step explanation:

We need to use algebra and equations.

A = P x (1 + (R/n)/100)^nt

our amount (A) is $72K

the number of times we compound the money (n) is 12 (12 months in a year, 'compounded monthly')

our rate (R) is 9 (9%)

our time (t) is 6 (6 years)

we need to find our principal/initial amount (p)

72000 = p x (1 + 0.0075)^12x6

p = $42042.50
