You would drive 420 miles.
You have to first fine how much you drive in 1 hour. So you divide 300 by 5.
That equals 60 miles per hour. So then you must multiply 60 times 7 to get 420 miles.
Complementary angles add up to 90°, if say the angle is "x", then
x + 54.6° = 90°
x = 90° - 54.6°.
The equation of a line is y = mx + b where m is the slope and b is the y-intercept (the point where the line crosses the y-axis). we can look at the graph and see that the line crosses the y axis at y = 4. Therefore, the y-intercept, b, is 4.
Now we must calculate the slope. To do so, we divide the "rise" of the line,
y₂ - y₁ by the "run" of the line x₂ - x₁. We must choose two points (x₁, y₁) and (x₂, y₂) to find the slope. Two points are already given to us, (1, 2) and (4, -4):
m = (-4 - 2)/(4 - 1)
m = -6/3
m = -2
Now that we know the slope and the y-intercept, we can simply plug them back into the equation to find the equation of the line:
y = -2x + 4
Not the way you wrote it, it isn't. Nothing you wrote is repeated, and
there's no note saying that the 561, or the 61, or the 1 repeats.
