Hey there!
2x^2 - 5 / x + 9
= 2(-1)^2 - 5/ -1 + 9
= (2(-1)^2 - 5) / (-1 + 9)
= (2(1) - 5) / 8
= (2 - 5) / 8
= -3 / 8
≈ -0.375
Therefore, your answer is:
-3/8 OR -0.375
EITHER OF THOSE SHOULD WORK BECAUSE THEY ARE EQUIVALENT TO EACH OTHER!
Good luck on your assignment & enjoy your day!

Answer:
A) 0 (no solutions)
Step-by-step explanation:
Solve the equation:
3x - 10(x+2) = 13 - 7x
3x - 10x -20 = 13 - 7x
-7x - 20 = 13 - 7x
-20 = 13
Since both sides are clearly not equal to each other, no solution can satisfy both sides to be equal to each other. So A is correct.
Answer:
-1.5
Step-by-step explanation:
2 times -1/4 is -0.5. -0.5 times 3 is -1.5
Answer:
11
Step-by-step explanation:
7-(-4) is 11. You must make the subtraction symbol in the middle to addition, since you have 2 negatives. Two negatives = postive. So after you do that it would be 7+4=11
Hope this helped!
