Answer:
Its 9
Step-by-step explanation:
The number next to the x its the slope when you have that form of a line
Answer:
C and D
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (- 3, - 6) and (x₂, y₂ ) = (9, 3) ← 2 points on the line
m =
=
= 
Using (a, b ) = (9, 3 ) , then
y - 3 =
(x - 9) → C
Using (a, b ) = (- 3, - 6 ), then
y - (- 6) =
(x - (- 3) ) , that is
y + 6 =
(x + 3) → D
Answer:
x=4 y=1
Step-by-step explanation:
given equation
x+y=5
so x= 5-y.......(i)
and
x-2y=2
so x= 2+2y........(ii)
then
5-y=2+2y
therefore y=1
and x=4
Answer: x = 11
Step-by-step explanation:
x+3 = 42/3 = 14
x = 11
Answer:
I have no idea if this would be right but I am guessing (for the 1/5 one) if you put 5 different colored marbles in a container and wanted to pull out a red one. You can also do this for the 1/10 one just use a different object.
