This is a function
Step-by-step explanation:
The vertical line test is a test where you take a straight vertical line and move it from right to left. If during the test, the line touches two points at the same time, it's not a function. In this case, it is a function since it passes the vertical line test.

Which numbers complete the blanks when solving the equation cos(x+2π) = - √2/2 over the interval [0,2π]
Answers
Answer:
x = 3π/4, 5π/4
Step-by-step explanation:
cos(x+2π) = -√2/2, [0,2π]
cos(x)cos(2π)-sin(x)sin(2π) = -√2/2
cos(x) = -√2/2
x = 3π/4, 5π/4
Remember that the cosine function is periodic, so cos(θ+2π)=cos(θ).

Identify the range of values for x.
Answers
Answer: Overall, the steps for algebraically finding the range of a function are:
Write down y=f(x) and then solve the equation for x, giving something of the form x=g(y).
Find the domain of g(y), and this will be the range of f(x). ...
If you can't seem to solve for x, then try graphing the function to find the range.

f(x)=17,000(0.87)x
The value of a certain SUV, in dollars, x years from its model year can be predicted by the exponential function shown in the table.
x| 0| 1| 2| 3| 4| 5|
g(x)| 21,000| 18,690| 16,634.10| 14,804.35| 13,175.87| 11,726.52|
How much more will the SUV be worth than the car 5 years after their model years? Round your answer to the nearest cent.
Answers
Using the exponential function, it is found that the SUV is worth $3,253.36 less than the car after 5 years.
The exponential function for the value of the SUV, after x years, is given by:
[tex]f(x) = 17000(0.87)^x[/tex]
Hence, after 5 years, the value is:
[tex]f(5) = 17000(0.87)^5 = 8473.16[/tex]
From the table, after 5 years, the car is worth $11,726.52.
11726.52 - 8473.16 = 3253.36.
The SUV is worth $3,253.36 less than the car after 5 years.

(b) A sum of money was to be shared among three friends Keisha, Tracey, and Kerry-Ann, in the
ratio 7:9:11 respectively. If Kerry-Ann received $3,300.00, find the sum of money that was
between the three friends.
Answers
The sum of the money that was between the three friends is $8100.
Let x represent the amount of money given to the three friends to share.
Keisha, Tracey, and Kerry-Ann shared the money in the ratio 7:9:11 respectively.
Since Kerry-Ann received $3300, hence:
(11/27) * x = 3300
11x/27 = 3300
x = $8100
The sum of the money that was between the three friends is $8100.

Hey there!
Solve for x :
Answer :x = 2 ✅
Explanation:9x + 4 = 5x + 12
>> Substract 4 from both sides :
9x + 4 - 4 = 5x + 12 - 4
9x = 5x + 8
>> Substract 5x from both sides :
9x - 5x = 5x - 5x + 8
4x = 8
>> Divide both sides by 4 :
4x / 4 = 8 / 4
x = 2

40. Let C be the total number of cupcakes. Then 2/3 x C + 1/6 x C = 200.
Combining , 5/6 x C = 200. So C = 240.

The point (x,y) = (4,2) is on the line
Use slope intercept form to find the y intercept
y = mx+b
