Answer:
24
Step-by-step explanation:
If she did all 3of them today then you subtract a day from each one then it would look like this
5+4+15=24
Answer:
1999
Step-by-step explanation:
y = 0.2313(y - 1992)^2 + 2.600(y - 1992) + 35.17
verify with known data point
y = 0.2313(2004 - 1992)^2 + 2.600(2004 - 1992) + 35.17
y = 0.2313(12)^2 + 2.600(12) + 35.17
y = 27.9873 + 28.6 + 35.17
y = 99.6772 which verifies our equation
65 = 0.2313x² + 2.6x + 35.17
0 = 0.2313x² + 2.6x - 29.83
quadratic formula
x = (-2.6 ±√(2.6² - 4(0.2313)(-29.83))) / (2(0.2313))
x = (-2.6 + 5.86) / 0.4626 = 7.05 years
7.05 = y - 1992
y = 1999.05

Answer:
slope m = 0
Step-by-step explanation:
To find the slope for two points, you need use
m = (y2 - y1)/(x2-x1)
for point 1 (-1, -4) and point 2 (-2, -4)
m = (-4 - (-4)) / ((-2)-(-1))
m = 0 / -1
when the top number is zero, the answer is 0
if you plot the points in a graph, it is a horizontal line or y = mx + b = 0m -4
y = -4
