The factors of 13 are 1 and 13 .
13 is a "prime" number.
Bow hello IQR is 21 + 1 -1 = 21
Answer:
Step-by-step explanation:
The first parabola has vertex (-1, 0) and y-intercept (0, 1).
We plug these values into the given vertex form equation of a parabola:
y - k = a(x - h)^2 becomes
y - 0 = a(x + 1)^2
Next, we subst. the coordinates of the y-intercept (0, 1) into the above, obtaining:
1 = a(0 + 1)^2, and from this we know that a = 1. Thus, the equation of the first parabola is
y = (x + 1)^2
Second parabola: We follow essentially the same approach. Identify the vertex and the two horizontal intercepts. They are:
vertex: (1, 4)
x-intercepts: (-1, 0) and (3, 0)
Subbing these values into y - k = a(x - h)^2, we obtain:
0 - 4 = a(3 - 1)^2, or
-4 = a(2)². This yields a = -1.
Then the desired equation of the parabola is
y - 4 = -(x - 1)^2
Answer:
Step-by-step explanation:
Zero in on the highest power of x. It's 4. Thus, this polynomial is of the 4th degree.
Note: Please use " ^ " to indicate exponentiation:
-2x^4 - x^3 + 8x^2 - 12
If you would like to solve <span>2/5 * (15x - 20) = 3 * (3x - 4), you can do this using the following steps:
</span>2/5 * (15x - 20) = 3 * (3x - 4)
6x - 8 = 9x - 12
-8 + 12 = 9x - 6x
4 = 3x
x = 4/3 = 1 1/3
The correct result would be 4/3.
