Remember you can do anything to an equation as long as you do it to both sides
(y/4)-49=-9
isolate the variable
add 49 to both sides
y/4=40
multiply both sides by 4 to clear fraction
y=160
Answer: you keep adding 2 and 1/3 to get your answer. 18 day so the dog food should last up to 18days hope this helps
Dont take my word not 100% sure
Answer:
(a) 3
Step-by-step explanation:
Calculate the slope m of the line given using the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (0,3) and (x₂, y₂ ) = (3, 2)
m =
= - 
given a line with slope m then the slope of a line perpendicular to it is
= -
= -
= 3 → (a)
