Answer:
- 439
Step-by-step explanation:
- s ( x ) = 2 - x²
- t ( x ) = 3x
- s ( t ( -7 ) ) = ?
--------------------------
- t (-7) = 3 * ( -7 ) = -21
- s ( t ( -7 ) ) = s ( -21 ) = 2 - ( -21 )² = 2 - 441 = - 439
- s ( t ( -7 ) ) = -439
Part A:it would be 32 dollars because 60 and 30 percent off is 42 dollars subtract 10 is 32
part b: yes it would be different the new total would be 35 because if you subtract 10 first it would be 50 then 30 percent off is 35
1.3y +3.2 = 1.3y +3.2
we notice that both sides of the equation are identical. So substitute y with any value and the equation would still be correct.
y has infinite solutions.
