A is your answer the this question
the discriminant formula is b^2-4ac
so plug the values from each equation into the formula and solve, the result is the value of the discriminant
if the number is negative, there are no real roots/x-int
if it is 0 there is one real root/x-intercepts
if it is positive it has 2 real roots/x-int
and to find the actual solutions you have to plug the values into the quadratic formula
This would be an increase. You would have one fraction with 46 over 24 and next to it you would have X over 100. Multiply 46 times 100 and then divide that number by 24. This would be an increase of approximately 191.6
Answer:
Step-by-step explanation:
Number of boys = g - 7.
g - 7 + g = 23
2g = 30
g = 15.
The are 15 girls in the class.
B
5,000
because the library has more than or = to 5000 books.
