Answer:
y=2/5x-15
Step-by-step explanation:
y-y=m(x-x¹)
y-(-11)=2/5(x-10)
y+11=2/5x-4
-11 -11
y=2/5x-15
Answer:
x = 1 ; x = -7/2
Step-by-step explanation:

Here the sol. of x =
1) x - 1 = 0
=> x = 1
2) 2x + 7 = 0
=> 2x = -7
=> x = -7/2
Answer:
52 tickets cost $10 and 18 tickets cost $12
Step-by-step explanation:
10x+12y=804. (1)
x+y=70. (2)
From (2)
x=70-y
Substitute x=70-y into (1)
10x+12y=804
10(70-y)+12y=804
700-10y+12y=804
700+2y=804
2y=804-700
2y=104
y=104/2
y=52
Recall
x+y=70
x+52=70
x=70-52
x=18
