Answer:
C
Step-by-step explanation:
The equation of a line passing through the origin is
y = mx ( m is the slope )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (- 3, 1) ← 2 points on the line
m = 
= - 
y = - x ← equation of line
Answer:
(x, y) -> (-x,-y)

Step-by-step explanation:
Let x be the total no. of strawberries, Let Sue be "S", Let Jim be "J" and Dan be "D"
S = 2x/7
J = 54+S -> J = 54+(2x/7)
D = 78
J+D = 5x/7
54+(2x/7)+78 = 5x/7
132+2x/7 = 5x/7
132 = (5x/7)-(2x/7)
132 = 3x/7
132*7 = 3x
924/3 = x
x = 308.
Therefore, there were initially 308 strawberries in the basket.
Of which; Sue had two-sevenths: 88, Jim had 142 and Dan had 78
To verify our answer, add these to see if we get 308
S+J+D = 308
88 + 142 + 78 = 308

Step-by-step explanation:
Factor x3−4x2−9x−36
Cannot factor
1 yard = 3 ft
if you have 20 yards you have to multiply it by 3 to know how many feet you have
20 x 3 = 60ft , so now Ginny is not correct because 20 yards is = to 60 ft
