Answer:
Step-by-step explanation:
x-4y=2
4y=x-2
y=1/4 x-1/2
slope=1/4
4x+y=8
y=-4x+8
its slope=-4
product of slopes=1/4×(-4)=-1
so lines are perpendicular.
Answer: it would be 99
Step-by-step explanation:
because of the rate it is going at it will be 99
2=5
3=10
4=17
5=??
Answer: 26
There is a pattern. It is squared then added with one.
For visual reference-
2=5 (2*2=4, 4+1=5)
3=10 (3*3=9, 9+1=10)
4=17 (4*4=16, 16+1=17)
5=?? (do the same thing)
so
5=26 (5*5=25, 25+1=26)
