Answer: sry
Step-by-step explanation:
Simplifying that would be 3 * (-7) -10+25 = -6. Combining like terms will get us to -21 +15 = -6, going further will be -6 = -6. Remember Order of Operations. Since -6 = -6, the equation is true.
Answer:
The number that goes in place of the question mark is 2.
Step-by-step explanation:
Let's solve it!
3x² + 12x - 24 = 0
First we can factor 3 out of each term:
x² + 4x - 8 = 0
Now we'll add 12 to both sides to complete the square:
x² + 4x + 4 = 12
And finish it off:
(x + 2)² = 12
So the answer to the question is 2
Bonus:
We can also now solve this for x:
(x + 2)² = 12
x = √12 - 2
x = 2√3 - 2
x ≈ 2 × ±1.732 - 2
x ≈ 1.464, -5.464
Answer:
D
Step-by-step explanation:
The end behavior is found by following the arrows on the graph. Here, the right end of the curve tends to infinity in both x- and y-directions.
The left end of the curve tends to negative infinity as the value of x approaches 0 from above.
These observations are summarized in the attachment.
