X+3=45 find the answer to X
If she got 5/100 wrong she got 95%
95% is the same as 0.95
Directly means when x goes up by 3 then y goes up by 3
it is represented by
y/x=k where k stay the same
so y=-21
x=3
the equation is -21/3=-7
k=-7
so k =-7
therfor
y/x=-7
then manipulate the equation
multiply boht sides by x
y=-7x
subsitute valuse for x and get values for y
if (x,y)
(1,-7)
(2,-14)
(3,-21)
so posiible equationscould be
-7/1=-7
-14/2=-7
-21/3=-7
and so on
Answer:
4,4? try that.. if not, I'm so sorry
