Answer:
270 Markers
Step-by-step explanation:
5 x 54 = 270
(sorry if I'm wrong)
B
160
4 is too low, 90 cant be divided by 8 and 160 is the only answer even though it is highest number
the answer is A. :)
f(x) = - 3x + 4
Note that y = f(x)
Given
9x + 3y = 12 ← Rearrange making y the subject
Subtract 9x from both sides
3y = - 9x + 12 ( divide all term by 3 )
y = - 3x + 4, thus
x=k+c over 7
7x-c+c=k+c
7x=k+c
divide both sides by 7
