when dividing exponents with the same base, you subtract them. so, 11-7 = 4
Solution: 240 + 85 + 40 = 365
475 - 365 = 110
Answer: Olivia needs 110 points on her final exam in order to earn at least a B in Math.
Answer:
a) x = -6, 2 b) y = -12, c) minimum at y=-16
Step-by-step explanation:
y = x² + 4x - 12
The x intercepts are where the graph crosses the x-axis (y=0):
0 = x² + 4x - 12
0 = (x + 6) (x - 2)
x = -6, x = 2
The y intercept is where the graph crosses the y-axis (x=0):
y = (0)² + 4(0) - 12
y = -12
The max or min is at the vertex of the parabola, which happens at x = -b / (2a):
x = -4 / (2*1)
x = -2
At x=-2:
y = (-2)² + 4(-2) - 12
y = -16
Since the leading coefficient is positive (+1 x²), this is an upwards parabola, so the vertex is the minimum.
