Answer:

B. 9

Step-by-step explanation:

4(x – 2) = 3x + 1

Distribute the 4

4x-8 =3x+1

Subtract 3x from both sides

4x-3x -8 =3x-3x+1

x-8 =1

Add 8 to each side

x-8+8=1+8

x=9

Math help please, thank you!

The answer to the first question of the attached document is option 1. We obtain the answer subtracting the term n from the series with the term n-1.For example:
 -3 - (- 5) = 2
 -1 - (- 3) = 2
  1 - (- 1) = 2
 So you can see that the common difference is the 2.

 The answer to the second question is option 3:
 y = | x + 7 |
 We can confirm it by substituting values in the equation.
 For example:
 if we do y = 0 then x = -7
 if we do x = 0 then y = 7.
 As corresponds in the graph shown.
 Remember also that as a general rule yes to the equationy = | x | whose vertex is in the point (0,0) we add a positive real number "a" of form y = | x + a | then the graph of y = | x | will move "to" units in the negative direction of x.

 The answer to the third question is option 4.
 The quotient of x and "and" is constant.
 k = y / x
 Rewriting:
 y = kx
 You can see that it corresponds to the equation of a line that passes through the origin, this means that and is proportional to x and both vary directly

In most places, it is only possible to see 2,000 stars in the nighttime sky due to light pollution. This is 4/15 as many stars a
emmainna [20.7K]

Let the no. of stars one can expect to see at Bryce Canyon be x.

Given that : No. of stars visible in the night sky = 2000

Also, given that, it is 4/15 of x.

Now, we have

\frac{4}{15}x = 2000\\\\x= \frac{2000 * 15}{4} = 7500

∴  You can expect to see 7,500 stars at Bryce Canyon.

Which quantity is proportional to 35/80
Talja [164]

Answer:

35/80

u want to find a number that is proportional to 35/80, then all u need is a number that is equivalent...another words, if it is proportional, it is an equivalent fraction to 35/80.

there can be several answers to this...such as 35/80 reduces to 7/16...so 7/16 is proportional....or if u multiply numerator and denominator by the same number, u will find a proportional number...

example :

35/80 * 2/2 = 70/160...this is proportional

35/80 * 3/3 = 105/240...this is proportional

35/80 * 4/4 = 140/320...this is also proportional

and so on....

so without giving us any answer choices, there can be many numbers to choose from
