Answer:
27in
Step-by-step explanation:
1ft=12in
(12*2)+3=27in
So weight=x
blood=y
we got that when
y=kx
when y=4.6, then x=160
4.6=160k
divide both sides by 160
0.02875=k
the direct variation is
y=0.02875x
so plug in x and get y
the answers in (x,y) form is
(0,0)
(50,1.4375)
(75,2.15625)
(100,2.875)
(125,3.59375)
(150,4.3125)
Answer:
y = 12+3x/6
Step-by-step explanation:
Make sure y is on one side and no terms are with it.
6y = 12+3x
y = 12+3x/6
Answer: (-1,3)
(0,1)
(1,-1)
(2,-3)
Step-by-step explanation: For example, you put -1 as x in the equation, and then solve, your answer would be the y, and the number you inputted would be the x.
