Answer:
-3
Step-by-step explanation:
plug in 2 where a is
f(a)=-4(2)+5
f(a)=-3
The total number of magazine copies that the bookstore has is 96.
On the first day, the bookstore sold 1/3 copies ofmagazine among the total of 96.
Then the number of magazines sold on the yesterday = 96 * (1/3)
= 32
Number of magazines left in the bookstore now = 96 - 32
= 64
So the bookstore sold 23 magazines on the yesterday.
Number of magazines sold by the bookstore today is 1/8 of the total magazines left.
Then the number of magazines sold today by the bookstore = 64 * (1/8)
= 8
Then the number of copies that the bookstore has left = 64 - 8
= 56
Y = 11 x + 1
11 x + 12 y = 12
----------------------
11 x + 12 * ( 11 x + 1 ) = 12
11 x + 132 x + 12 = 12
143 x + 12 - 12 = 12 - 12
143 x = 0
x = 0
y = 11 * 0 + 1
y = 0 + 1
Answer:
y = 1
Answer:
y=-3x+20
Step-by-step explanation:
3/4x+1/4y=5
-3/4x -3/4x
1/4y=5-3/4x
divide the whole entire equation by 1/4 like this: (4)1/4y=4(5-3/4x)
Your answer is y=-3x+20
