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:
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
Answer:
$5728
Step-by-step explanation:
$4000 is deposited into an account with 4.8% interest.
We assume that there are no withdrawals from the account.
Then we are asked the determine the amount will be there in the account after 9 years.
From the formula of simple interest, the final amount in the account after 9 years will be 
dollars. (Answer)
<span>(x^2-4x-6) factors into:</span>
(x -5.1623) (x+1.1623)
Therefore x = 5.1623 and x = -1.1623
(4x^2-8x-2) <span>factors into:
(x -2.2247) * (x +2.2474)
</span>
Therefore x = 2.2247 and x= -0.22474
Answer:
Step-by-step explanation:
First, find the <em>rate of</em><em> </em><em>change</em><em> </em>[<em>slope</em>]:
Then, plug these coordinates into the <em>Slope-Intercept Formula</em> instead of the <em>Point-Slope Formula</em> because you get it done much swiftly. It does not matter which ordered pair you choose:
35 = 4[3] + b
12
Then convert to <em>Standard</em><em> </em><em>Form</em>:
y = 4x + 23
- 4x - 4x
__________
_______________________________________________
19 = 4[−1] + b
−4
Then convert to <em>Standard Form</em>:
y = 4x + 23
- 4x - 4x
__________
** You see? I told you it did not matter which ordered pair you choose because you will ALWAYS get the exact same result.
