Answer:
y = -0.3x + 103
Step-by-step explanation:
✔️Find the slope (b):
Slope = ∆y/∆x
Using, (25, 95.5) and (35, 92.5),
Slope (m) = (92.5 - 95.5)/(35 - 25) = -3/10 = -0.3
✔️Find the y-intercept (b):
Substitute (x, y) = (25, 95.5) and m = -0.3 into y = mx + b
95.5 = -0.3(25) + b
95.5 = -7.5 + b
95.5 + 7.5 = b
103 = b
b = 103
✔️To write the equation, substitute m = -0.3 and b = 103 into y = mx + b
Thus:
y = -0.3x + 103
Answer:
(4,1)
Step-by-step explanation:
The vertex of the quadratic can be found using -b/2a. The vertex is the point (-b/2a, f(-b/2a)).
To find the x coordinate of the quadratic, define its a,b, and c. The quadratic has a = 2, b=-16, and c=31. Then -b/2a is -(-16)/2(2) = 16/4 = 4.
To find the y-coordinate, input the x=4 and solve for y.
The vertex is (4,1).
373-13=360
360 divided by three equal to 120
So 120 children chose basketball
Answer:
In the number 36,521 the digit 5 is in one position lower than it is in the provided number, which means it's value is 1/10th of the original digit.
Step-by-step explanation:
It will take them 6 hours to travel 300 miles. How I got my answer: 160 divided by 3.2 = 50 miles per hour, 300 divided by 50 = 6 hours. Hope I could help! :D
