You move y so that it’s by itself then add common variables (Comment if you want a more detailed explanation)
The answer would be
Y= -6/3x +3 (for the 1st equation)
Y= -3/2x +4.5 (for the 2nd equation)
Answer:
y=10/3x+5
Step-by-step explanation:
If we know the cost of a ticket is $7, we can then write an equation in slope-intercept form for the amount it will cost to buy any amount of tickets.
If we denote x as the amount of tickets purchased, and c as the total cost, we can write the equation:

Since we can vary the amount of tickets purchased independently of the total amount, x (the amount of tickets purchased) will be the independent variable.
However, since y (the total cost) is directly dependent on the amount of tickets that are purchased, c is the dependent variable.
This problem Is an example of geometrica progression. The formula
for the sum of geometric progression is:
S = a[(r^n)-1] / (r – 1)
Where s is the sum
a is the first term = 1
r is the common ratio = 2 ( because it doubles every year
n is the number of terms = (19) since the first term is when
he was born which he still 0
s = S = 1[(2^19)-1] / (2 – 1)
s = $524,287

Answer:
See attached image for the graph of the function
Step-by-step explanation:
Notice that this is the product of a power function (
) times the trigonometric and periodic function cos(x). So the zeros (crossings of the x axis will be driven by the values at which they independently give zero. That is the roots of the power function (only x=0) and the many roots of the cos function:
, and their nagetiva values.
Notice that the blue curve in the graph represents the original function f(x), with its appropriate zeros (crossings of the x-axis), while the orange trace is that of "-f(x)". Of course for both the zeroes will be the same, while the rest of the curves will be the reflection over the x-axis since one is the negative of the other.
