<h3>Explanation:</h3>

<u>We know that:</u>

  • The y-intercept of an equation is the constant.
  • Constants are the <u>numerals</u> in the equation.

<u>Finding the y-intercept.</u>

In the equation provided, we can see only one <u>constant.</u>

  • => y = 1x² + 7x - 5

Thus, the y-intercept is -5.

To find the y-intercept substitute x as 0

y = 1 \times  {0}^{2}  + 7 \times 0 - 5

y = 1 \times 0 + 0 - 5

y = 0 + 0 - 5

y =  - 5

  • <em>Thus, The y-intercept is -5...~</em>

Step-by-step explanation:

To get the correct answer, you can count the total number of shaded tenths and the total number of shaded hundredths and then regroup.

There are 9 shaded tenths and 18 shaded hundredths. Regroup 10 hundredths into 1 tenth to get 10 tenths and 8 hundredths. Then regroup the 10 tenths in one whole, giving you 1 whole and 8 hundredths. The product is 1.08.

Another way to get the answer is to count the total number of shaded hundredths. There are 108 hundredths. Regroup 100 of them as one whole, giving you 1 whole and 8 hundredths.

A population of deer mice consists of 200 individuals and has an r = 0.1. A population of wood rats consists of 100 individuals
Mariulka [41]

Answer:

Population of dice mice after one year = 2000

Population of wood rats after one year = 1000

The population of deer mice is growing faster than the popular of wood rats

Step-by-step explanation:

The expression for population = dN/dt = rN

Upon integration N = rN²/2

Therefore for population N = 200 and r= 0.1

N after one year = (0.1 x 200²)/ 2 = 2000

Therefore for population N = 100 and r= 0.2

N after one year = (0.2 x 100²)/ 2 = 1000

Hence the population of deer mice is growing faster than the popular of wood rats

Which of the following lists of orders pairs is a funtion
nordsb [41]

Answer:

D


Step-by-step explanation:

For it to be a function, every x value must have 1 unique y value ONLY.


In option A, you can see that the x value of 1 has 2 y values, 1 & 5. So it's not a function.


In option B, you can see that the x value of 0 has 2 y values, 0 & -4. Moreover, the x value of 4 also has 2 y values, 2 & -2. So it's not a function.


In option C, you can see that the x value of -2 has 2 y values, 4 & -4. This is not a function as well.


In option D, each x value has a unique y value that are different. So this is a function.


Answer is option D.
