Step-by-step explanation:
I'll do line A for you and you can use the formulas to solve lines B and C yourself, since its good for you to practice doing these questions yourself
a)
The gradient, m, is calculated using m = (y2-y1)/(x2-x1) where x1,x2,y1 and y2 can be any ordered pairs on the line. I'm going to use (4,0) and (7,3) as the 2 points.
m = (3-0)/(7-4) = 3/3 = 1
b)
The y-intercept is where the line intersects with the x-axis. In this case (0,-4)
c)
The equation of a linear line is y=mx+b (or c depending on which country you are from)
y = 1x-4
y=x-4
Now try the other 2 lines yourself!

Answer:
<h3>
Step-by-step explanation:</h3>
A)answer: A cross section is the two-dimensional shape that results from cutting a three-dimensional with a plane.
B)answer: A cross section is the face you obtain by making a "slice" through a solid object. A cross section is two-dimensional. ... When a plane intersects a solid figure, the cross sectional face may be a point, a line segment, or a two-dimensional shape such as, but not limited to, a circle, rectangle, oval, or hexagon.
Answer: Yes
Step-by-step explanation:
Each value of y maps onto one value of x.
Option C
The zeros of the polynomial function f(x) = x^3 - 5x^2 - 6x is x = 0 and x = -1 and x = 6
<h3><u>Solution:</u></h3>
Given that polynomial function is f(x) = x^3 - 5x^2 - 6x
We have to find the zeros of polynomial
To find zeros, equate the given polynomial function to 0. i.e f(x) = 0
Taking "x" as common term,
Equating each term to zero, we get
Thus one of the zeros of function is x = 0
Now let us solve 
We can rewrite -5x as -6x + x
Taking "x" as common from first two terms and -6 as common from next two terms
Taking (x + 1) as common term,
(x + 1)(x - 6) = 0
x + 1 = 0 and x - 6 = 0
x = -1 and x = 6
Thus the zeros of given function is x = 0 and x = -1 and x = 6
Working backwards, we first subtract 1. That is 228. Next you divide 228 by 4, which is how many parts they have in all. That is 57. 57 times 3 is how much ben has. Your answer is 171.
