B. By solving for x, you get x=8.39,x=-2.39.
(5x+7)(2x−3) is the answer
Answer:
f(12) = - 20
Step-by-step explanation:
To evaluate f(12), substitute x = 12 into f(x), that is
f(12) = - 2(12) + 4 = - 24 + 4 = - 20
For the first 1 X= 11 because all you need to do is add or subtract the numbers visible.
The second would be 2.
Answer:
13. is a solution of the equation. 14. and 15. are both inequalities.
Step-by-step explanation:
the equal sign is something you can look out for to decide if it is a solution to the equation. the > sign means 'greater than' and the ≤ means 'less than' or 'equal to'. both are not equals, therefore they are inequalities.
