The x intrercepts is where the function crosses the x axis; In other words, it is where the output of the function is 0.
In a quadratic, you can start by factoring, if it’s unable to be factored then use the quadratic formula. Also, it is good to use the discriminate.
D= Discrimminate
D>0 2 real solutions
D=0 1 real solution
D<0 2 imaginary solutions.
The discrimminate is the equation/expression under the radical of the quadratic formula. With this formula, it’s not factorable. Using the discriminate it is also seen, as you’ll get a negative in the square root. This is imagenary because you cannot take the root of a negative value, which is why “i” is used to represent the square root of negative one.
I believe it is B because the dots are solid, therefore it would only include numbers between -2 and 4
The correct answer to this question should be 3,600
Answer:
Step-by-step explanation:
12X-20=5-3X
12X+3X=5+20
16X=25
X=25/16=1.56
What I would do is divide $46.50 by 6 and see what I get. What did you get?
