Answer:
70% or 175 students
Step-by-step explanation:
3/10 is equivalent to 30/100 which is the same thing as 30 percent
41 increased by d is 41+d
Y=2x and y = x² - 3. To find the intersections of these 2 functions we proceed as follows:
2x= x²-3 → x² - 2x -3 =0
The zeros of this trinomial are x = 3 and x =-1
Now to find y-coordinates replace in any of the initial equation x by both values:
y = 2x . For x = 3 , y = 6
and for a = -1, y = -2
