Answer:
B. y - 2x = 5
Step-by-step explanation:
Add 2x to both sides, and the equation becomes, y = 2x + 5, as demonstrated from the graph.
Answer: 2
Step-by-step explanation:
This is a direct proportion. Since y varies as x. This will be:
y = kx
where,
y = 9
x= 3
9 = 3k
k = 9/3
k = 3
Find x when y=6
y = kx
6 = 3x
x = 6/3
x = 2
2 bags of corn chips + 8 bags of potato chips + 5 bags of ??? = 15 bags total
2/ (5+8+2) = Probability
3x - 3y = -12 ------------- (1)
7x + 2y = -19 --------------(2)
(1) x 2 : 6x - 6y = - 24 ----------- (1a)
(2) x 3 : 21x + 6y = -57 ----------- (2a)
(1a) + (2a) : 27x = - 81
x = - 3
Sub x = -3 into (1) : 3(-3) - 3y = - 12
y = - 12 + 9
y = - 3
Answer( -3, -3)
Answer:
Half of 24 is 12, and if all 12 have been red, then the other 12 are all black.
