Salomon tracks the weight of his new puppy every 2 weeks. She weighs 10 lbs the
Gekata [30.6K]

Equation (B) "y = 3x + 10" represents the growth of the puppy.

<h3>What are equations?</h3>
  • An equation is a mathematical formula where the "equal to" sign appears between two expressions having the same value.
  • Like 3x plus 5 equals 15, for example.
  • Different types of equations exist, such as linear, quadratic, cubic, and others.
  • The three primary forms of linear equations are the slope-intercept form, standard form, and point-slope form.

So, the equation that represents the situation:

  • The weight increase is: (10, 13, 16, 19, 22, 25)
  • We can observe that every time, there is a rise of 3lbs of weight.
  • Now, let 10 be a constant as the weight is starting from 10 lbs.
  • And 'x' be the number of time Salomon tracks the weight.

Then:

  • y = 3x + 10

For example, Salomon checks the weight for the 6th time then:

  • y = 3x + 10
  • y = 3(5) + 10
  • y = 15 + 10
  • y = 25

So, the equation is correct.

Therefore, equation (B) "y = 3x + 10" represents the growth of the puppy.

The correct question is given below:
Salomon tracks the weight of his new puppy every 2 weeks. She weighs 10 lbs the day he brings her home. His list for her first 6 "weighs" is as follows: (10, 13, 16, 19, 22, 25}

Which equation represents the growth of the puppy? Select one:

A. y = x + 3

B. y = 3x + 10

C. y = 10x + 3

D. y = x + 10

Henry borrowed $770 from his friend at 6.875% simple annual interest for 8 months. What is the total amount that Henry will repa
tester [92]

The total amount to be repaid is equal to $949.66

Step-by-step explanation:

Simple interest is a type of interest that is usually applied on short term loans, where when a payment is made towards this kind of interest the payment first goes towards monthly interest, and then the remainder is reverted towards the principal.

FORMULA FOR CALCULATING SIMPLE INTEREST =

Here principal = $922

        interest rate = 6%

        time period = 6 months (when made per annum it will be 6/12)

SIMPLE INTEREST IS EQUAL TO $27.66

The total amount that is to be repaid is equal to

  PRINCIPAL + SIMPLE INTEREST

= $922 + $27.66

= $949.66
