Your additional details state that “negative 9 less then seven minus fourx less the equal to nine.” Maybe you mean negative 9 less than seven minus four x LESS THAN OR EQUAL to nine. Because you also said you couldn’t combine the underscore with the less than sign. You can write it instead as <= (read as less than or equal). If that's the case, the solution is: -9 < 7 - 4x <= 9 Add -7 to all -16 < -4x <= 2 Multiply -4 to all 4 > x >= -8

or

-8 <= x < 4 which in interval notation is: [-8,4)

a million) 10x – 17 < 2x + 7x 10x < 9x + 17 10x - 9x < 17 x < 17 two) 25% of 60 25% = a million/four 60 * (a million/four) = 15 three) 6<7/2a+(-eight) 6+ eight < 7/2a 14(2a) < 7 28a < 7 a > (7/28) a > (a million/four) four) F= ly l = F/y five) P= a+m+okay a= P-m-okay 6) One quantity is 9 lower than one other. Their sum is 11. Find the numbers. (Enter answers from smallest to biggest.) 10-nine = a million a million+10=eleven for that reason smallest quantity is a million and biggest is 10. 7) Use the method 3x + 5y = nine to uncover y if x is three. y=(nine-3x) / (five) y=(nine-nine) / five y= zero / five y= zero eight) Solve the inequality. Write the answer set in period notation. 31.ninety three > 4x – zero.07 32 > 4x eight < x nine)Solve the inequality. Write the answer set in period notation. x + 7 > eight x > a million 10) Solve the compound inequality. Write the answer set in period notation. -10
