for these you need to rearrange the equations and do substitutions.
#3 = if x+y=5 then you know x = 5-y
now substitute that equation for x in the 2nd one so x + 2y = 8 becomes
5-y + 2y = 8 2y - y becomes 1y which becomes y then subtract 5 from each side to get y =3
now replace y with 3 in the first equation x = 5-3 so x = 2
so (2,3) is the answer
same type of work for #4
2x-y=6 ,S0 y = 2X+6
so now you have 4x+2(2x+6)=-4
that becomes 4x +4x+12 = -4
8x+8 = 1, x =1
y = 2(1)-6 = -4
so answer is (1,-4)
Answer: hello your question is incomplete attached below is the missing part
answer : There is no slope
Step-by-step explanation:
To interpret the slope we plot a graph of Winter severity index vs Fawn count
slope = Δy / Δx = 0
attached below is the graph
There no slope because the graph is a curve and not a straight line graph
Answer:
10
Step-by-step explanation:
Price of baseball hats without shipping = $130.49 - $3.99 = $126.50
Number of baseball hats he ordered: $126.50 ÷ $12.65 = 10
