Answer:25%
Step-by-step explanation:
1. increase=new number-original number
increase=2.25-1.80
increase=0.45
2. increase %= increase÷ original number × 100
%= 0.25× 100
%=25
Answer: -1.3
Step-by-step explanation:
Answer:
26
Step-by-step explanation:
3x^2 + 7x
when x = 2,
=> 3(2)^2 + 7(2)
=> 3(4) + 14
=> 12 + 14
=> 26
Answer:
I like to compare them all the same. Put all the equations in slope intercept form y=mx+b
So you need to isolate y.
Step-by-step explanation:
Main equation to compare y=2/3x + 4
If they have the same slope they are parallel. If they have opposite reciprocal slopes then they are perpendicular.
First one is y=2x +12 neither
Second one is y= -3/2x -1 perpendicular
Third one is y= 2/3x - 1 parallel
Forth one is y= 2/3x + 11/3 parallel
