What is an Equation?

An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.

Given that,

Fixed amount he earns per week = $15

Additional amount added depending on the number of subscription sold = $3

Let x be the number of subscription sold.

Amount earned in a week = 15 + 3x

If amount earned is $90,

15 + 3x = 90

3x = 75

x = 75 / 3 = 25

Hence the number of subscriptions is 25.

what's the domain function for y=(x+1)(x-9)

Answers

Answer:

Step-by-step explanation:

Division by zero is undefined, so the only restriction on the domain, the values of x is that x cannot equal 9. So the domain is all real numbers except 9. Or in interval notation

x=(-oo,9),(9,+oo)

Answer:

All real numbers

Step-by-step explanation:

y = (x+1)(x-9)

y = x² - 8x - 9

There are no asymptotes, restrictions of x, or holes.

Answers

Complete question :

From the set {24, 36, 72}, use substitution to determine which value of x makes the inequality true.

x ÷ 12 < 3

Answer:

24

Step-by-step explanation:

Given the inequality : x ÷ 12 < 3

Substitute the values in the set for X and test the inequality expression if it hoods true for each of the substituted value.

x = 24

24 ÷ 12 < 3

2 < 3 (true)

x = 36

36 ÷ 12 < 3

3 < 3 (false)

x = 72

72 ÷ 12 < 3

6 < 3 (false)

A $3,000 deposit for 66 months compounded at an annual interest rate of 1.6%. What is the interest and the account balance at the end of the 66 months

Answers

Answer:

interest: $275.77balance: $3,275.77

Step-by-step explanation:

The account value is given by the compound interest formula:

  A = P(1 +r/12)^n

Principal P invested at annual rate r compounded monthly for n months.

__

Using your parameters, the account balance would be ...

  A = $3000(1 +0.016/12)^66 = $3275.77 . . . account balance

The interest is the difference between this balance and the original investment amount:

  interest = $3000 -3275.77 = $275.77 . . . interest
