Answer:
y=-2x+11
Step-by-step explanation:
equation of a line
y-b=m(x-a)
m=-2
a=3
b=5
sub into the equation
y-5= -2(x-3) multiply out the brackets and a negative multiply by negative equals positive
y-5=-2x+6
y=-2x+11
or
2x+y-11=0

Step-by-step explanation:
10. The perimeter of any shape is the sum of the length of the sides, which means that the perimeter of this triangle is x+y+z.
11. Since this is a right triangle, the two legs form the height and base. The area of this triangle is therefore x*y/2.
12.
a. x=3, y=4, z=5
b. 
c.
Hope this helps!
Answer:
y=-4x+9
Step-by-step explanation:
a line parallel to another line means the two lines have the same slope
so you can already cross out the second and last equation
the y-intercept is 9 so it is positive, not a negative 9
Volume of oblique cylinder
= (base area) * height (perpendicular to base)
= (30 π )*m
= 30m π cm^3
