1) y= -4x+c
2) y= 3x+c replace x and y to find c , 5=3(2)+c
C= -1
Y=3x-1
3) find slope first m=y2-y1/x2-x1 = 0-(-1)/-2-1 = 1/-3 and now you have y= -1/3x+c to find c just replace any of the given points , 0= -1/3(-2)+c
C= -2/3 and so y= -1/3x-2/3
4) DO THE SAME STEP AS NUMBER 3 and enjoy!
Answer:
Length = 45 inches and Width = 20 inches
Step-by-step explanation:
Let the width be w.
Length(l)=2.25w
Area = 900 in^2
The formula for the area of a rectangle is Area = length * width
So substituting our values we get:

So we get width = 20 inches
Length = 2.25w
so Length= 2.25*20
=45 inches
Answer:
Step-by-step explanation:
The following statements are true:
B. As the absolute value of the negative slope gets smaller, the
graph of the line gets less steep.
E. The line goes down from left to right.
Answer:
3
Step-by-step explanation:
a term is the number and/or variable in between of the symbols
P(t)= A(1/2)^(t/h)
P(t)=10(1/2)^(16/8)
<em>(1/2)^(16/8) =.25</em>
P(t)=10(.25)
P(t)=2.5
Therefore the answer is B. 2.5mg.
