It equals 1 1/6 + d.
In other words, one and one sixth plus d.
Costs her 10 so minus 10 from profit
earns 3 per pound
so if she sells x pounds and profit is y then
profit=number of pound sold times cost per pound minus shipping or
y=3x-10
the equation is y=3x-10
it intercepts the y axis at y=-10
intercepts the x axis at x=10/3
some points on the graph are (0,-10) (1,-7) (2,-4), (3,-1), (4,2) etc
see which one is that graph
Answer: it's the third one and the first one
Step-by-step explanation:
Answer: The required co-ordinates of point T are (13, -6).
Step-by-step explanation: given that S is the midpoint of the line segment RT, where the co-ordinates of point R are (-9, 4) and that of S are (2, -1).
We are to find the co-ordinates of point T.
We know that
the co-ordinates of the mid-point of a line segment with endpoints (a, b) and (c, d) are given by
Let (h, k) be the co-ordinates of point T. Then, according to the given information, we have
and
Thus, the required co-ordinates of point T are (13, -6).
Option 2: f(x) = (x-8)(x-7)
x-8 = 0 ⇒ x = 8
x-7 = 0 ⇒ x = 7
