Answer: x = 1
Step-by-step explanation:
(any line with an undefined slope is a vertical line)
x = 1 has an undefined slope and passes through (1,8)
Answer:
x = 1
Step-by-step explanation:
The line of symmetry is defined as the x value of the vertex of a parabola.
To find the vertex of a parabola, we need to convert to vertex form.
Vertex form looks like this:
, where -h is the x value of the vertex and k is the y value of the vertex.
H is also defined as 
where a is the coefficient of x squared and b is the coefficient of the x term.
The coefficient of the x squared term is 1 and the coefficient of b is -2.
Plugging in, we get 
, which is equal to 1. This can then be plugged into the equation as
, but k doesn't matter because all we need is the x-term. Now, our x-term is negative h, which is negative negative one, which is positive one. Therefore, our answer is x = 1.
Decrease = 500000 - 420000 = 80000
Percent decrease = 80000 / 500000 x 100% = 16%
Use of word “amount” is irritating as in English this only used for measurements.
“Number” of cars would be better grammar.
-x^4
The degree is the exponent, and he amount of degrees there are depends on the amount of degrees in each monomial.
In this case, there is only one monomial, with it's degree as 4
4 is your answer
hope this helps
Answer:
Solution,
First term (a) = 25
Common difference (d) = Second term - first term = 20 - 25 = -5
Now,
nth term = a + (n - 1)d = 25 + (n - 1) (-5) = 25 - 5n +5 = 30 - 5n
The nth term of the series is 30 - 5n
