“Find the value of x if 30(3x-10)”

step one: multiply the 30 by the two terms which are 3x and 10.
- 90x-30

step two: divide by thirty
90x-30/30 = 3x-1

x=3x-1
x+1=3x-1+1
x+1=3x
x+1-x=3x-x
1=2x
1/2=2x/2
1/2=x

answer: x equals 1-2

The graph of f(x) = (0.5)x is replaced by the graph of g(x) = (0.5)x − k. If g(x) is obtained by shifting f(x) down by 5 units,

tekilochka [14]

Answer: The value of k is 5 units.

Step-by-step explanation:

Since we have given that

The graph of f(x)=0.5x is replaced by the graph of g(x) = 0.5x-k

If g(x) is obtained by shifting f(x) down by 5 units,

Then the graph of f(x) = 0.5x is replaced by the graph of g(x) = 0.5x-5

Hence, k = 5 units

Therefore, the value of k is 5 units.

Two simple question Brainliest, 5 stars and Thanks too you pls HELP!!!!

Setler79 [48]

Answer:

$\Huge\boxed { 1/4}$

$\Huge\boxed {226•333. miles}$

Step-by-step explanation:

$\huge\pink{\boxed{\green{\mathcal{\overbrace{\underbrace{\fcolorbox{Black}{aqua}{\underline{\pink{✩1.solusion✩}}}}}}}}}$

1. ⟾ one dozen = 12, so 2 dozen = 12×2=24

⟾ 24 Joe's doughnuts = $6

⟾ 1 Joe's doughnuts or unit / rate = $6/24 = $1/4.

⟾ so per doughnut unit rate is $ 1/4.

$\huge\pink{\boxed{\green{\mathcal{\overbrace{\underbrace{\fcolorbox{Black}{aqua}{\underline{\pink{✩2.solusion✩}}}}}}}}}$

2. ⟾ 24 hours = 5432 miles.

⟾ 1 hours = 5432/24 hours

⟾ 1 hours = 226•333 miles.

⟾ so aryan drove in 226•333 miles in 1 hours.

Hope it's helps you

Tell whether the sequence 1/3, 0, 1, -2 ... is arithmetic, geometric, or neither. Find the next three terms of the sequence.

max2010maxim [7]

Answer:

A. neither; 7, -20, 61

Step-by-step explanation:

The sequence 1/3, 0, 1, -2 ...

The difference between the terms are; -1/3, 1, -3......

Looking the difference between consecutive terms in the sequence, we can predict the next differences between the following terms, as the differences form a geometric sequence;

Therefore; -1/3, 1, -3, 9, -27, 81

Thus; the sequence will be;

1/3, 0, 1, -2 , (-2+9), (-2+9+-27), (-2+9+-27+81)

1/3, 0, 1, -2, 7, -20, 61

Hence the next three terms are; 7, -20, 61
