Answer:
1. The graph represents a proportional relationship
2. 70,000 miles
Step-by-step explanation:
1. The graph represents a proportional relationship since the graph line is straight and begins at the origin.
2. Plot 5.5 hours on the graph and it'll give you 70,000 miles
11.28 cm is the answer to this problem.
First, eliminate the lowest grade (76). Now, find the average/mean of the remaining 4 test grades. To do so, add up all the test grades, then divide them by the total number of test grades:
80+84+91+95=350
350/4=87.5
Hope this helps!!
Answer:idk im on the quiz and im stuck just like you
Step-by-step explanation:
Answer:
The equation of the line would be y = -1/4x + 2
Step-by-step explanation:
In order to solve this, start by finding the slope of the original line. You can do this by solving for y.
28x - 7y = 9
-7y = -28x + 9
y = 4x - 9/7
Now that we have a slope of 4, we know that the perpendicular slope is -1/4 (since perpendicular lines have opposite and reciprocal slopes). We can use this and the new point in point-slope form to find the equation.
y - y1 = m(x - x1)
y - 1 = -1/4(x - 4)
y - 1 = 1/4x + 1
y = -1/4x + 2
