Line 1--------- >(0,2) (1,-1)
y=mx+b m=(-1-2)/(1-0)=-3
2=(-3)*(0)+b----- > b=2
y1=-3x+2Line 2--------- >(0,-1) (2,2)
y=mx+b m=(2+1)/(2-0)=3/2

y2=(3/2)x-1
<span>using a graphic tool
see attached figure</span>
the best estimate solution for the system is <span>
(1, 1)
because </span>is the only one within the range of the x axis (-5,5) and the y axis (-5,5)
-l-7+3l = -|-4| = -4
Answer:
-4
Answer:
f(x)=60[1/3]^x
initial value⇒ x=0, f(x) = 60*[1/3]^0 = 60*1 = 60
x=1 ⇒f(1) = 60*[1/3]
x=2 ⇒f(2) = 60*[1/3]^2 = f(1) * [1/3]
x = n ⇒ f(n) = 60*[1/3]^n=60*[1/3]^(n-1)*[1/3] = f(n-1)*[1/3]
Then, the right choice is: the graph has an initial value of 60, and each successive term is determined by multiplying by 1/3
Step-by-step explanation:
i think this is what your looking for
4b+3s=72
6b+3s=96
Multiply the second equation by -1
-6b-3s=-96
Now you can cross out the +3s -3s
-2b=-24
Divide both sides by -2
b=12
s=8
So blouses cost $12 each and skirts cost $8 each
