a = 6b = 9a + b = 6 + 9 = 15

Set it up like this: B+9=8+6B+9=14B=5

= a + b - 2

The answer is 144. The compound operator for (a) and (b) in each pair is a * (a+b). For 9 and 7, this is 9 x (9+7) = 9 x 16 = 144.

b = 6

It is b + 9.

Set it up like this: B+9=8+6B+9=14B=5

= a + b - 2

The answer is 144. The compound operator for (a) and (b) in each pair is a * (a+b). For 9 and 7, this is 9 x (9+7) = 9 x 16 = 144.

-3

Only when a and b have the same sign (or when a or b equals 0). Here are some examples: |2+4|=|2|+|4|--> |6|=|6|--> 6=6 TRUE |(-1)+(-3)|=|(-1)|+|(-3)|--> |(-4)|=1+3--> 4=4 TRUE |3+(-6)|=|3|+|(-6)|--> |(-3)|=3+6--> 3=9 FALSE

4+5=9

b = 6

Perpendicular equation: y = ax+14 Slope of line: 2-6/1-b = -1/a Multiply both sides by 1-b: -4 = -1+b/a By trial and improvement: -4 = -1+9/-2 By trial and improvement: -4 = -1-9/2.5 Therefore: a = -2 and b = 9 or a = 2.5 and b = -9

3 times a times a times b

It is: b+4 when simplified
