Answer:
the percent of people that end up coming as error is 12%
Answer:
m = -7
initial value = 27
Step-by-step explanation:
The rate of change is also known as the slope of a line.
To find this do y1-y2/x1-x2 or y2-y1/x2-x1. You can't do rise/run in this case because there is no graph. I will help you with both answers for the first question only, because I think it is better for you to also practice.
The initial value is also when x = 0, therefore the initial value is 27.
The slop is:
27-(-8)/0-5
35/-5
-7
The rate of change, or slope, for the first question is -7.
3c=12+8d
c=12+8d/3
c=4(3+2d)/3
Use y2-y1/x2-x1
So 0-5/3-2
-5/1= m= -5
Then plug it into y=MX+B
0= -5(3)+b
0= -15+b
b=15
y=-5x+15
So I hope this helps but I'm not sure how to plug it into that's equation. The rest of my work is rigt
X+6=y thats the answer i got
