2)
a*2 + b = 26;
a*(-4) + b = -16;
then, a*6 = 42 => a = 7 => b = 26 -14 => b = 12;

from table, 7*9 + 12 = 63 + 12 = 75, correct;
7*(-8) + 12 = -56 + 12 = -44, correct;

slope = ( -44 + 16) / ( -8 + 4) = ( - 28) / (-4) = 7 = a;

HERE ARE TWO NUMBER MACHINES A AND B

nika2105 [10]

Answer:

$x=-7$

Step-by-step explanation:

We can write them both like functions like this

$A=5x-4$

$B=3x+8$

Where

x=input

A=Output A

B=Output B

We want the output of A 3 times the output of B this can be written like this:

$A=3B$

we replace with the functions

$5x-4=3(3x+8)$

we solve for x

$5x-4=9x+24\\5x-9x=24+4\\-4x=28\\x=\frac{28}{-4}\\x=-7$

The output that makes the out put of A 3 times teh output of B is $-7$
