How many solutions does 9x - 18 = 3(3x - 6) have?

Step-by-step explanation: Since the line crosses the y-axis at 6, the y-intercept is 6.

Answer: 500 messages will the costs for the two plans be the same.

Step-by-step explanation:

Let x= Number of text messages .

Given: One plan has a monthly fee of $15 with a charge of $0.05 per text.

i.e. Total cost of plan = 15+0.05x

The other plan has a monthly fee of $5 with $0.07 per text.

i.e. Total cost of plan = 5+0.07x

As per given ,

[tex]5+0.07x=15+0.05x\\\\\Rightarrow\ 0.07x-0.05x=15-5\\\\\Rightarrow\ 0.02x=10\\\\\Rightarrow\ x=\dfrac{10}{0.02}\\\\\Rightarrow\ x= \dfrac{1000}{2}\\\\\Rightarrow\ x=500[/tex]

Hence, 500 messages will the costs for the two plans be the same.

Answer:

3.0 x 10^1

Step-by-step explanation:

Step 1) 4,500,000,000 / 149,600,000 = about 30

Step 2) 3.0 x 10^1 = 30

If the hydronium concentration increases, the pH decreases, causing the solution to

become more acidic. This happens when an acid is introduced. As H+ ions dissociate from the acid and bond with water, they form hydronium ions, thus increasing the hydronium concentration of the solution

Answer:

-x + 16

Step-by-step explanation:

We need to use the distributive property to solve this!

We can isolate this into 2 parts that we will need to combine later on, but isolating them will make it less confusing to simplify:

2(x+5) is one part, and the second is -3(x-2)

The first part simplifies to 2x + 10, and the second simplifies to -3x + 6. Now we need to combine the 2 values.

2x + 10 - 3x + 6

Combine like terms

-x + 16 is your answer!

Answer:

Step-by-step explanation:

2x+10 - 3x -5 and for the fun of it the answer will be..

you will subtract 10 and 5 and that gives you 5

then you do -3+2 = -1x

5 divided by -1 gives you

X= -5

Answer:

One pound of ground beef costs $2.75.

Step-by-step explanation:

To solve this you want to divide both numbers by 3.4 this is because you want to find out much the ground beef costs per 1 pound and 3.4 / 3.4 = 1. Additionally, what you do to one side you must do to the other!

3.4 / 3.4 = 1

9.35 / 3.4 = 2.75

One pound of ground beef costs $2.75.

Answer: g(x) = 3*Ix + 2I - 5

Step-by-step explanation:

First, let's define the transformations in a general way.

A vertical stretch of a scale factor A, is written as:

g(x) = A*f(x)

A vertical shift of A units is written as:

g(x) = f(x) + A

if A is positive, the shift is up, if A is negative, the shift is down.

A horizontal shift of A units is written as:

g(x) = f(x - A)

If A is positive, the shift is to the right.

If A is negative, the shift is to the left.

Then we start with the absoulte value parent function f(x) = IxI

"The graph of the absolute value parent function is vertically stretched by a factor of three"

We start with:

g(x) = 3*f(x)

"then shifted two units left"

g(x) = 3*f(x - (-2))

"and five units down."

g(x) = 3*f(x + 2) - 5.

and knowing that f(x) = IxI, we have:

g(x) = 3*Ix + 2I - 5

B

Step-by-step explanation:

Answer:

3

Step-by-step explanation:

we want to get (n) alone

3n+17=26

subtract 17 from each side

3n=9

divide each side by 3

n=3

3

Answer:

A

Step-by-step explanation:

3n+17=26 Inverse operation of addition is subtraction so subtract 17 from both sides of the equation

3n-17+17=26-17

3n=19 Inverse operation of multiplication is division, so divide 3 from both sides of the equation so you can get n alone

3n/3=9/3

n=3

Inverse operation means the opposite operation

Answer:

$1281

Step-by-step explanation:

[tex]8540 \times \frac{15}{100} \\ 1281 [/tex]

Step-by-step explanation:

-24+12d=2(d-3)+22

-24+12d=2d-6+22

12d-2d=-6+22+24

10d=40

10d/10=40/10

d=4

Pretty sure is 5 bud.

Answer:

Step-by-step explanation: There are no solutions whenever k=4,5mod9.

This holds since it is not difficult to verify that for every integer n, we have n3=0,±1mod9.

Up till this year, there were just two values for k in the range 1..100 for which it was not known if there were a solution. These values are k=33,42.

Both values are now known to have solutions. See 42 is the answer to the question “
