Answer:

x = 14

Step-by-step explanation:

45 = 3(x + 1)

Distribute the 3

3(x) = 3x

3(1) = 3

We now have 45 = 3x + 3

Subtract 3 from both sides

45 - 3 = 42

3 - 3 cancels out

We now have 42 = 3x

Divide both sides by 3

42/3 = 14

3x / 3 = x

We're left with x = 14

Answer:

The answer is 3/2 or 1 1/2

Step-by-step explanation:

First, you have to make it as a improper fraction :

$- 2 \frac{1}{4}$

$= - \frac{( 2 \times 4) + 1}{4}$

$= - \frac{9}{4}$

$- 1 \frac{1}{2}$

$= - \frac{(1 \times 2) + 1}{2}$

$= - \frac{3}{2}$

Next, you can divide it by cutting out the common factor :

$- \frac{9}{4} \div - \frac{3}{2}$

$= - \frac{9}{4} \times - \frac{2}{3}$

$= - \frac{ 3}{2} \times - 1$

$= \frac{3}{2}$

$= 1 \frac{1}{2}$

Please help with math

pshichka [43]

I did some research, and I think it's the first one. PLEASE CORRECT ME IF I'M WRONG!!
Here's why, because the first segment extends from 0 to 1. So, x has to be 0 or larger, but less than 1 or 1.

Answer:

a = 5120

b = 1.25

Step-by-step explanation:

Let the exponential function representing the given table is,

f(x) = $a(b)^x$

Here, f(x) = Number of views

x = Number of weeks

We choose two points from the given table and satisfy the equation of the function.

Let the points are (0, 5120) and (1, 6400)

For a point (0, 5120),

f(0) = a(b)⁰ = 5120

a = 5120

Now for the second point (1, 6400),

6400 = 5120(b)¹

b = $\frac{6400}{5120}$

b = 1.25

Therefore, a = 5120 and b = 1.25 are the values.
