Answer:
0 ≤ x ≤ 30
Step-by-step explanation:
In the month of September, a bird population increased by a factor of 1.25 every day for those 30 days. The function below shows the number of birds, f(x), after x days:
f(x) = 250(1.25)ˣ
Which of the following is a reasonable domain for the function?
0 ≤ x ≤ 250
0 ≤ x ≤ 30
All positive integers greater than 100
All real numbers
Solution:
Given that f(x) = 250(1.25)ˣ, where x is the number of days and f(x) is the population of the birds after x days. This means that at the beginning of the month of September (i.e. at x = 0), the population of the birds was 250. And as each day goes by, the population of the bird increases by a factor of 1.25.
The domain of a function is the set of all possible independent variables. In this case the number of days (x) is the independent variable. Since in the month of September there are 30 days, therefore the domain is:
0 ≤ x ≤ 30
a certain number is added to 9 the result is 5 - the same number what is the number
Answer:
the answer to the question is -2
Step-by-step explanation:
a certain number=x
therefore,x+9=5-x
x+x=5-9
2x= -4
you the divide both sides by2 to gain x

Calculate the marked price (original price) if
a. After 25% discount, the price of an article is Rs 7500,
Answer:
Step-by-step explanation:
let original price of an article be x
marked price(price after discount )=Rs 7500
discount%=25%
discount =discount % of cost price
=25/100*x
=25x/100
=x/4
Mark price=original price-discount amount
Rs 7500=x-x/4
Rs 7500=4*x-x/4
Rs 7500*4=4x-x
Rs 30000=3x
Rs 30000/3=x
Rs10000=x
therefore original price of an article is Rs 10000.

If you add the two equations 6x + 4y 46 and — 6x + 9y = 6 what do you get?
Answer:
13y = 52
Step-by-step explanation:
6x - 6x + 4y + 9y = (46 + 6)
6x - 6x + 4y + 9y = 52
0 + 4y + 9y = 52
0 + 13y = 52
13y = 52
(p.s. y = 4)

A) Yes, the ordered pair is a solution
B) No, the ordered pair is not a solution.
Given:
The inequality is:
[tex]-4x-7y<15[/tex]
To find:
The whether (-6,3) is a solution of given inequality of not.
Solution:
We have,
[tex]-4x-7y<15[/tex]
We need to check the inequality for point (-6,3).
Substitute [tex]x=-6, y=3[/tex] in the given inequality.
[tex]-4(-6)-7(3)<15[/tex]
[tex]24-21<15[/tex]
[tex]3<15[/tex]
This statement is true. It means the point (-6,3) satisfies the given inequality.
Therefore, the correct option is A. Yes, the ordered pair is a solution.
The value of the 9 in 901,532 is how many times the value of the 9 in 157,900?
NEED HELP!!!
Answer:
the answer for this question is 1000times.
Step-by-step explanation:
the value for 9 in 157,900 is nine hundred(900).and the value of 9 in 901,532 is nine hundred thousand(900000).
900×1000= 900,000.
The place value of the number 9 in the first number is 1000 times greater than the second number.
What is the standard decimal form of numbers?The standard decimal form of numbers is written in base 10 as there are 10 different numbers from 0 to 9.
Each digit has a face value and a place value.
Given, A number 901,532, So the place value of the number 9 is 900000.
And, In the number 157,900, The place value of 9 is 900.
Therefore, The number of times the value of 9 is greater in 901,532 compared to 157,900 is,
= 900000/900.
= 1000 times.

What is the first step you will use to solve this equation:
4x +2 = 7x - 13
1. Subtract 2 from both sides of the equation
4x + 2 = 7x - 13
4x + 2 - 2 = 7x - 13 - 2
2. Simplify
4x + 2 - 2 = 7x - 13 - 2 -----> 4x = 7x - 13 - 2 -----> 4x = 7x - 15
3. Subtract 7x from both sides of the equation
4x = 7x - 15
4x - 7x = 7x - 15 - 7x
4. Simplify
4x - 7x = 7x - 15 - 7x -----> -3x = 7x - 15 - 7x -----> -3x = -15
5. Divide both sides of the equation by the same term
-3x = -15
-3x/-3 = -15/-3
6. Simplify
-3x/-3 = -15/-3
x = -15/-3
x = 5
7. Solution
x = 5

Describe the relationship between GF and CD when the two lines are perpendicular to AB. Also describe the relationship between GF and CD when CD is not perpendicular to AB . Zoom in or out on the coordinate plane, if needed.
Answer:
See Explanation
Step-by-step explanation:
Given
Lines GF, CD and AB
Required
Relationship between GF and CD
The question is incomplete, as there is no attachment to support the given parameters.
The general solution goes thus:
(a) CD and GF perpendicular to AB
If two lines are perpendicular to another line; then the two lines are parallel to each other.
This means that CD and GF are parallel, and they have the same slope
(b) CD is not perpendicular to AB
Here, we know that GF is perpendicular to AB, CD is not;
This means that GF and AB are not parallel.
More information is needed to determine the actual relationship between GF and AB; but for sure, they are not parallel.

Answer:
288 square inches
Step-by-step explanation:
since we are not told what to find, we can as well find the volume of the prism
Volume of the prism = BH
B is the base area = 1/2 * 6 * 8
B = 48/2
B = 24 square inches
H is the height of the prism = 12in
Volume of the prism = 24 * 12
Volume of the prism = 288 square inches
for a smoothie Isaac needs 3 quarts of strawberry puree which is sold in bottles of 1 pint and bottles of 1 cup he already had 1.75 quarts of puree if he wants to buy exactly three bottles in total how many of each bottle should he buy pleasee help its really important
Answer:
There are 2 bottle of 1 pint and 1 bottle of 1 cup.
Step-by-step explanation:
Okay, so first let's look at the conversion factors of these units:
1 quart=2 pints & 1 quart= 4 cups.
Alright well, we already have 1.75 out of 3 quarts of the strawberry puree so all
we need left is 1.25 quarts left. So since 1 pint= .5 quarts and 1 cup=.25 quarts
we need to buy 2 pints and 1 cup to give us our three quarts.
Hence, there are 2 bottle of 1 pint and 1 bottle of 1 cup.
Hope this answer helps you :)
