Answer:

  y = 2x +1

Step-by-step explanation:

The line rises 2 units for each 1 unit to the right, so its slope is ...

  m = rise/run = 2/1 = 2

The line crosses the y-axis at y = 1, so the y-intercept is ...

  b = 1

Then the slope-intercept form equation is ...

  y = mx + b . . . . . . . for slope m and y-intercept b

  y = 2x + 1 . . . . . . . . fill in the known values

Ratio is the quantitative relation between two amounts, which is being compared. In this question we are considering the ratio of weight to time consumed.

At the age 0

Weight = 2 pound

At the age 4 months

Weight = 3.5 pound

Proportion of Change = Change in Weight / Change in time = (3.5 - 2) / (4-0) = 1.5 / 4 = 0.375 pound per month

Weight after 6 months = 2 + (6 x 0.375 pond per month )= 4.25 pound

The sum of three numbers is 108. The second number is 4 times the third. The first number is 6 more than the third. What are the
Dvinal [7]

Answer:

The numbers are <u>23, 68 and 17</u>.

Step-by-step explanation:

Given:

The sum of three numbers is 108.

The second number is 4 times the third.

The first number is 6 more than the third.

Now, to find the numbers.

Let the third number be x.

The second number be 4x.

And the first number be 6+x.

According to question:

(6+x)+4x+x=108

<em>Now adding the variables we get:</em>

⇒6+6x=108

<em>Subtracting both sides by 6 we get:</em>

⇒6x=102

<em>Dividing both sides by 6 we get:</em>

⇒x=17.

Third number =  17.

Second number =  4x=4\times 17=68.

First number = 6+x=6+17=23.

Therefore, the numbers are 23, 68 and 17.

1. A sunflower grows at a rate of 3.5 cm per day, for the first 28 days.

Here, the growth of the sunflower per day is uniform i.e. 3.5 cm.

2. After the car is purchased the value of a car depreciates at a rate of 15% per year.

Here, also the the depreciation of the car's value is equal i.e. 15% of initial value per year.

3. During an experiment, the amount of bacteria in a culture triples every two days.

Here, the growth of bacteria count is not equal per day because the bacteria count per day increases exponentially. (Answer)
