The quadratic equation is given by:
y = 3x² + 10x - 8
The standard equation of a parabola is given by:
y = ax² + bx + c
Where a, b, c are constants
At point (4, 80):
80 = a(4)² + b(4) + c
16a + 4b + c = 80 (1)
At point (-3, -11):
-11 = a(-3)² + b(-3) + c
9a - 3b + c = -11 (2)
At point (-1, -15):
-15 = a(-1)² + b(-1) + c
a - b + c = -15 (3)
Solving equations 1, 2 and 3 simultaneously gives:
a = 3, b = 10, c = -8
Therefore the quadratic equation becomes:
y = 3x² + 10x - 8

Answer:
I believe its 2 so sorry if im wrong
Step-by-step explanation:
Answer:
The Line p
y= 3/4x+ 6.25
Step-by-step explanation:
The points given changed 4 right and 3 up, giving a slope of .75
plug this slope into (1,7) to get the y-intercept. This shows the intercept at 6.25.
Answer:
$8,440
Step-by-step explanation:
5.5% of 8,00 = 440
8,000 + 440 = 8,440
