Answer:
I think the answer is C
Step-by-step explanation:
First you need to find 2 coordinates on the graph. (2,3) (4,6)
Use the formula M= y2-y1 ÷ x2-x1
Then m= 6-3 ÷ 4-2
Then m= 3÷2 = 1.5
So the slope should be 1.5 or 1 1/2
The x-intercept is point where the graph cuts the x-axis, while the y-intercept is the point where the graph cuts the y-axis. The y-intercept in a straight line equation normally represents some initial amount. Thus the correct answer that can be deduced from our graph is:
x-intercept is 400
y-intercept is 800
Thus the correct description is:
Ayita opened a bank account with $800
Mean is the average
So the first mean is 11
The second one is 14.7 so round to 15
15-11 is 4. Hope that is correct
X=60° (equilateral triangle)
y=120°
Working: (360°-120°)/2
F(x)= -8x²
f(-3)= -8* (-3)²
f(-3)= -8 * 9
f(-3)= -72
