Answer:
y = 156
Step-by-step explanation:
The equation for direct variation is
y = kx
65 = k*5
Divide each side by 5
65/5 = k
13 =k
The equation is y = 13x
Let x = 12
y = 13*12
y = 156
Answer:
k^2-18k+81
Step-by-step explanation:
Of course there is no way for them to be both correct, since they contradict each other.
Here is how to prove Ray incorrect. Suppose that a polynomial has four roots: s, t, u, and v. If the polynomial were evaluated at any of these values, it would have to be zero. Therefore, the polynomial can be written in this form.
p(x)(x - s)(x - t)(x - u)(x - v), where p(x) is some non-zero polynomial
This polynomial has a degree of at least 4. It therefore cannot be cubic.
Now prove Kelsey correct. We have already proved that there can be no more than three roots. To prove that a cubic polynomial with three roots is possible, all we have to do is offer a single example of that. This one will do.
(x - 1)(x - 2)(x - 3)
This is a cubic polynomial with three roots, and four or more roots are not possible for a cubic polynomial. Kelsey is correct.
Incidentally, if this is a roller coaster we are discussing, then a cubic polynomial is not such a good idea, either for a vertical curve or a horizontal curve.
pls double check these im not super sure
im p sure the first one with || means parallel n second one means perpendicular lol
Answer:
m= ll m= -1/3
m= ⊥ m= 3
Step-by-step explanation:
uh regular slope
m = -1/3
parallel - slope is same
perpendicular - product of slopes is -1
Answer:
Step-by-step explanation:
The System of equations is:
In order to solve the system of equations you need to find the value of the variable "x" and the value of the variable "y".
Then, you can follow the steps shown below:
Step 1. You can use the Equalization methods. Make . Then:
Step 2. You must solve for the variable "x" in order to find its value. This is:
Step 3. SUbstitute the value of "x" into any original equation:
Step 4. Evaluating, you get that "y" is:
