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:

Answer:

i.x=1      (x,y)=(1,3)

y=3

ii.x=2      (x,y)=(2,4)

y=4

iii.x=3      (x,y)=(3,5)

y=5

iv.x=4       (x,y)=(4,6)

y=6

v.x=5        (x,y)=(5,7)

y=7

Step-by-step explanation:

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

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

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.

No

Step-by-step explanation:

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:

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

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.

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.

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.
