Step-by-step explanation:

-x-4=4x-54

Adding x on both sides, we get

-x-4+x=4x-54+x
-4=5x-54

Adding 54 on both sides, we get

-4+54=5x-54+54
50=5x

Dividing both sides by 5, we get

50/5=5x/5
10=x

Hence, the value of x is 10.

Step-by-step explanation:

Aiden bought 60 candles.

0.37*60 is equal to $22.20

Aidens sister bought 170 candles at same price of $0.37

0.37*170=$62.90

Now subtract

$62.90-22.20=$40.70

She spent 40 more dollars or to be exact 40.70 dollars more then aiden

The number of views on an interesting video after it's uploaded is represented by the following table:

defon

Answer:

The model for V(t) ,the number of views, t ,months after it's uploaded, best fits the data is $,V(t)=50(6.25)^t$

Step-by-step explanation:

Time (months) Views

0 50

2 313

4 1950

6 12,210

8 76,300

10 476,800

$(x_1,y_1)=(0,50)\\(x_2,y_2)=(2,313)\\(x_3,y_3)=(4,1950)$

$Slope = \frac{y_2-y_1}{x_2-x_1}$

$Slope = \frac{313-50}{2-0}$

Slope =131.5

$Slope = \frac{y_3-y_2}{x_3-x_2}$

$Slope = \frac{1950-313}{4-2}$

Slope =818.5

Since the slope is not same . So, it is not a linear relationship

$\frac{y_2}{y_1}=\frac{313}{50}=6.25\\\frac{y_3}{y_2}=\frac{1950}{313}=6.25$

Since the ratio between the consecutive outputs is same so, it is exponential relationship.

Formula : $y=ab^t$

Where a is the initial value = 50

b = rate of change = 6.25

The model for V(t) ,the number of views, t ,months after it's uploaded, best fits the data

So $,V(t)=50(6.25)^t$
