Answer:
A
Step-by-step explanation:
32.77 Will be your answer
Answer:
C. (-5,0) and (3,0)
Step-by-step explanation:
y= x² + 2x-15
y = 0
x² + 2x-15 = 0
(x - 3) (x + 5) = 0
x = 3 or x = -5
Are you asking me to demonstrate how to handle that equation ?
Are you expecting to get the procedure and solution here ?
If you were asking a question, would that be it ?
Well, OK. You manipulated me into it.
5p + 2 = 4p - 1
Subtract 4p from each side: p + 2 = - 1
Subtract 2 from each side: p = - 3
Let the capacity of bus be x students
And van be y students, now ;
From the given statements we get two equations ~
multiply the equation (2) with 2 [ it won't change the values ]
Now, deduct equation (1) from equation (3)
Therefore each bus can carry (x) = 45 students
Now, plug the value of x in equation (1) to find y ~
Hence, each van can carry (y) = 17 students in total.
