Answer: domain: 0 ≤ x ≤ 8
Step-by-step explanation:
Domain is an independent variable with a minimum and a maximum value. Or the starting point (value) to the end point (value)
The time taken by the ball is from 0 to 8 seconds
The domain of the function represented by the graph will be from the starting time of the ball to the end time. Therefore, In this case, domain will be
0 ≤ x ≤ 8
Answer:
y = -.5x -.5
Step-by-step explanation:
All you do is plug in the x and y in the point to the equation, y = mx + b. Since the coordinate is (5, -3), this in the equation would look like -3 = -.5(5) +b. (all you need to find is the y-intercept, or b.) Solve it out to get -3 = -2.5 + b. Add 2.5 to each side of the equation, you're left with b = -.5. Now, put that back into the original equation, and get y = -.5x -.5. I think this is right, you can go back through and check once more if you'd like.
Answer:
B
Step-by-step explanation:
Because the number of degrees in a triangle is 180 degrees so x = 180 - (45 + 60) = 75. Now w + 75 = 180 , therfore w = 105 degrees.
Answer:
y=-3
Step-by-step explanation:
there is no slope so x will not be used in the equation it also crosses at -3
