Answer 1

Answer:

18x

Step-by-step explanation:

3x^2 - 27 = -18x

x^2 - 3x = -1x

-18x / -1x = 18x

3x^2 = 9

x^2 = 2x

Answer 2
Answer: 18x

Step-by -step: first you started with 3x^2 which is 9x then go to 9x-27 which is 18x
Next you go to x^2 with is also know as 1x^2 which can be 2. Then you subtract 2x -3x which can be 1x. Finally you divide 18x to 1x giving you the answer 18x

Answers

Answer:

its C got it on E2020

Step-by-step explanation:

A line does not extend from a side of a triangle to form angle 2. Then the correct option is C.

What is the triangle?

The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180°.

The exterior angle of a triangle is almost always equal to the addition of the interior and opposing interior angles. The term "external angle property" refers to this feature.

Choose the triangle in which angle 2 is not an exterior angle.

The external angle can be made when the line is extended and the angle is formed outside the triangle, which is known as the exterior angle.

A line does not extend from a side of a triangle to form angle 2. Then the correct option is C.

Third table  represents the second piece of the function f(x)

What is Inequality?

a relationship between two expressions or values that are not equal to each other is called 'inequality.

The given function is given by -3.5x+0.5, x<1 and 8-2x≥1

The second piece of the function f(x) is 8-2x ,x≥1

Now, we substitute some values of x and find the corresponding function values and check which table satisfy the points.

For x = 1

f(1)=8-2(1)=6

f(1)=6

For x = 2

f(2)=8-2(2)=4

f(2)=4

For x = 3

f(3)=8-2(3)=2

f(3)=2

Among the given tables, third tables contains these values.

Hence, Third table  represents the second piece of the function f(x)

The general formula for nth term of given sequence is:

[tex]G_n = 54 . (\frac{1}{3})^{n-1}[/tex]

Step-by-step explanation:

Given sequence is:

54,18,6.....

In order to write the general formula of a sequence, first of all the common ratio has to be found. Common ratio is the ratio between consecutive terms of a geometric sequence.

[tex]Here\\a_1 = 54\\a_2 = 18\\a_3 = 6\\And\\r = \frac{a_2}{a_1} = \frac{18}{54} = \frac{1}{3} \\r = \frac{a_3}{a_2} = \frac{6}{18} = \frac{1}{3}[/tex]

The general formula is:

[tex]G_n = A_1 (r)^{n-1}[/tex]

Putting the values of a1 and r

[tex]G_n = 54 . (\frac{1}{3})^{n-1}[/tex]

Hence,

The general formula for nth term of given sequence is:

[tex]G_n = 54 . (\frac{1}{3})^{n-1}[/tex]

For A party 10 friends are byinh 100 cups 100 plates a punchbowl and 200 balloons if the friends share the cost equally how much should each friend contribute ?
100 Balloons:$7.80
100 plates:$4.75
100 cups:$5.45
100 napkins:$2.09
10 invitations: $1.60
plastic punchbowl$11.50

Answers

Answer:

$2.58

Step-by-step explanation:

First, we should divide each number by 10 to get the amount per person we get...

10 cups

10 plates

20 balloons

Since the cost of cups, plates, and balloons is written as 100 of them, we just have to divide each of the by the amount we got after dividing by 10 and use that same amount and divide the money...

1. 10 cups is 1/10 of 100 cups so we divide $5.45 by 10 = .545

2. 10 plates is 1/10 of 100 plates so we divide $4.75 by 10 = .475

3. 20 balloons is 1/5 of 100 balloons so we divide $7.80 by 5 = 1.56

Now, we add them all up to get $2.58

Max scored 71 and 65 on his first
two tests in Biology 101. What is the
lowest he must score on the third
test to get an average for the
three tests above 77?

Answers

Answer:

Step-by-step explanation:

If he scored 71 and 65 and needs an average above 77, you took the average needed of 77 and times by 3 since you will have 3 test total. 3*77=231. Take the 231- what you already have which is 136, to get 95. He will need a score of at least 95 to average the 77. 71+65+95=231 231/3= 77

So, x≥95. X is the next test. It would need to be greater than or equal to 95.

Thomas observed that his friend blinked an average of three times every 15 seconds.
How many times should his friend blink in 65 second?

Answers

Answer:

13 blinks

Step-by-step explanation:

Step one:

given

number of blinks= 3

time taken to blink=15 seconds

the rate of blink is given as

rate= number of blinks/time taken

rate= 3/15

rate= 1/5 blinks per second, 0.2 blinks per second

Step two:

hence for a 65 second period, the number of blinks is

rate=number of blink/time

0.2=number of blink/9=65

cross multiply we have

number of blink=0.2*65

number of blink=13 blinks

The volume of a cube increases by a factor of 6 when its edge length doubles.
D The volume of a cube increases by a factor of 8 when its edge length doubles.

Answers

Answer:

D The volume of a cube increases by a factor of 8 when its edge length doubles

Step-by-step explanation:

Volume of a cube is represented by the function

[tex]V(x)=x^3[/tex]

where [tex]x[/tex] represents the edge length of the cube

Now when [tex]x=2x[/tex] i.e., when the edge length is doubled we have

[tex]V(2x)=(2x)^3\\\Rightarrow V(2x)=8x^3\\\Rightarrow V(2x)=8(V(x))[/tex]

It can be seen that the volume of the cube increased by 8 times when edge length doubles.
