Answer:
x-intercepts = 1,2, and 4, y-intercept = -8
Step-by-step explanation:
x^3 - 7x^2 - 14x - 8 in factored form is equal to (x-1)(x-2)(x-4).
Solving for x-intercepts:
We are actually able to solve for all x-intercepts without the given factor. But since we are given one of the factors, our job becomes much easier. Using synthetic division, or long division, we factor out the x-intercept 4. Which leaves us with the polynomial x^2 - 3x + 2. From here we can separate the polynomial into two binomials. x^2 - 3x + 2 = (x-1)(x-2). Giving us all 3 x-intercepts. Using Descartes' rules we can identify before even starting the problem how many real x-intercepts there are (Not needed for this problem). Solving for y-intercept:
The y-intercept is always the coefficient that does not have any assigned x-variables. The coefficient is -8, thus the y-intercept. If unsure of the y-intercept, you can always plug in x = 0. Solving for the y-intercept will give you the value of f(0). If there is no coefficient, the y-intercept is equal to zero.

Answer:
9:19
Step-by-step explanation:
Total number of students = 28
Number of boys = 19
Number of girls = Total number of students - Number of boys = 28-19 = 9
Therefore, ratio of girls to boys = Number of girls/Number of boys = 9/19 = 9:19
Answer:
(foh)(6) = -29
Step-by-step explanation:
(f o h)(6) is f(h(x)) when x = 6.
We have that:
f(x) = 4x - 1
h(x) = -x-1
f(h(x)) = 4(-x-1) - 1 = -4x - 4 - 1 = -4x - 5
(foh)(6) = -4(6) - 5 = -29
(foh)(6) = -29

17/7 cannot be put into a whole number, but it can be put into decimal form. The estimated decimal number is 2.43. You just divide 17 by 7 and then round.
The y-intercept is (0, -8)
