Answer:
Step-by-step explanation:
Use the Quadratic formula:
You can identify that, in this case:
Now you need to substitute these values into the formula:
Remember that:
Therefore,rewriting and simplifying, you get:
Then, you get the following roots:
1. Subtract x+7. x = 2
2. Subtract x+7. x = 8
3. Subtract x+3. x = 4
4. Subtract x+1, divide by 2. x = 9
5. Subtract x+1. x = 8
6. Subtract 2x+2. x = 3
7. Subtract x+3, divide by 3. x = 6
Answer:
A is correct
Step-by-step explanation:
A has no solution because since the slopes are the same, setting both equations equal to each other will cancel out the slopes and result in 8=16, meaning no solution will make both sides equal to each other.
B does have a solution because of different slopes
C does have a solution because of different slopes
D does have a solution because of different slopes
Only If the corresponding angles are in between the corresponding sides, than it would be ASA, or if the triangle was a right triangle and the hypotenuses and legs were congruent.
