<span>1) Name the variables
Number of days: x
rent: y
2) state the initial points
x y
days $
3 285
60 510
3) assume linear relation:
=> (y - yo) / (x - xo) = (y1 - yo) / (x1 - xo)
=> (y - 285) / (x - 3) = (510 - 285) / (60 - 3)
=> (y - 285) / (x - 3) = 225 / 57 = 75 / 19
=> 19 (y - 285) = 75 (x - 3)
=> 19y - 19*285 = 75x - 75*3
=> 19y - 75x = 5415 - 225
=> 19y - 75x = 5190
=> standar form = -75x + 19y = 5190
PART B: Write the equation obtained in Part A using function notation.
-75x + 19y = 5190
=> 19y = 5190 + 75x
=> y = 5190/19 + (75/19)x
=> function notation = f(x) = (75/19)x + 5190 / 19
PART C: Describe the steps to graph the equation obtained above on the
coordinate axes. Mention the labels on the axes and the intervals.
1) Coordinate axes:
x: number of days
y: rent
2) draw the two given points: (3,285) and (60, 510)
3) draw the line that joins those points from the interception of the y-axis until some points further (60, 510).

Answer:
8
Step-by-step explanation:
A quadrilateral with exactly one pair of parallel sizes
B
One triangle has 180°
33°+57°=90°
180°-90°=90
So Z is 90°
so it's a right triangle.

Answer:
16. k^5/j^3
18. 81y^20
Step-by-step explanation:
The applicable rules of exponents are ...
(a^b)(a^c) = a^(b+c)
(a^b)/(a^c) = a^(b-c) . . . . where b may be 0
(a^b)^c = a^(bc)
(ab)^c = (a^c)(b^c)
