Answer:
12
Step-by-step explanation:
Rearrange into the form y = mx + c, where m is the slope.
12x - y = 30
y = 12x - 30
m = 12
Answer:
3.019 hours.
Step-by-step explanation:
In this case they ask us to calculate the time in hours that are in those distances, for this we have the speed and the distance, we know that speed is equal to:
v = d / t
therefore the time would be:
t = d / t
we must pass the distance that is in kilometers to miles, like this:
350 km * 1 mile / 1.61 km = 217.4 mi
Now if replacing:
t = 217.4 / 72 = 3.019
Therefore, the time would be 3.019 hours.
The true statement about the quadratic function is that it has two distinct real zeros
<h3>How to interpret the quadratic function?</h3>
The given parameters are:
- x-intercepts = 2 i.e. intercepts the x-axis in two places
- y-intercept = 1 i.e. intercepts the y-axis in one place
The first highlight above means that, the function can be represented as:
y = a(x - x1)(x -x2)
Where x1 and x2 are the x-intercepts
This also means that the quadratic function has two distinct real zeros

3x + 7y = 14
Subtract 3x from both sides
7y = -3x + 14
Slope is equal to -3.
