Answer:(-6,-10)
Step-by-step explanation:
Let’s say that A is (-5,-6) and B is (-3,2). The slope of AB is (-6-2)/(-5+3)=(-8)/(-2)=4
The equation of AB is:
y-2=4(x+3)
y=4x+14
The lines intersect in:
4x+14=x-4
3x=-18
x=-6
(-6,-10)
1.4 as a decimal. 1.4=140
Answer:
Others 2367
Students 481
Step-by-step explanation:
Let x be students and y be others
x + y = 2848
x = 2848 - y...............(1)
2.50x + 3.75y = 10078.75
Substituting,
2.50(2848-y) + 3.75y = 10078.75
y = 2367
x = 2848 - 2367 = 481
Answer:
1/2
Step-by-step explanation:
