Answer:
boys = 705
girls = 783
Step-by-step explanation:
We are to find the number of boys and girls in the school
the answer can be determined using simultaneous equation
x = boys
y = girls
y - x = 78 equation 1
y + x = 1488 equation 2
subtract equation 1 from 2
2x = 1410
x = 1410/2 = 705
Substitute for x in equation 1
y - 705 = 78
y = 705 + 78 = 783
Answer:
y = 745,000
Step-by-step explanation:
They are asking for the y intercept (the original year)
y = -2.07x^2 +78.39x +745
y is in thousands
Let x =0 years
y = -2.07 * 0 +78.39*0 +745
y = 745
y is in thousands
y = 745,000
