The answer is 4.
36/63 = 0.57
4/7 = 0.57
The best way to answer this item is to use the Substitution method. Substitute the value of y from the first equation to the y of the second equation such that the second equation becomes,
-4x + 3(x - 4) = -3
Simplifying the equation,
-x = 9
Dividing both sides by -1 gives an answer of,
<em>x = -9</em>
Then, substitute the value of x in the first equation.
y = -9 - 4
<em> y = -13</em>
The answer to this item is letter B.
THE ANSWER ISSSSSSIS 52/9
Y = 3x....where y is # pgs read and x = # of minutes
0 minutes....x = 0
y = 3(0)
y = 0
ordered pair (0,0)
1 minute...x = 1
y = 3(1)
y = 3
ordered pair (1,3)
2 minutes...x = 2
y = 3(2)
y = 6
ordered pair (2,6)
3 minutes...x = 3
y = 3(3)
y = 9
ordered pair (3,9)
X 2^(-x) 4^(x+3)
-3 8 1
-2 4 4
-1 0 16
0 1 64
1 0.5 256
2 0.25 1024
3 0.125 4096
The solution is x = -2 because both functions return the same value, i.e. 4.
