Answer:
1.0 mph
Step-by-step explanation:
so there are 60 minutes in an hour
you need to find what her speed is per hour
right now it is per minute
so multiply her current speed by 60
88*60=5280
there are 5280 feet in a mile.
Her current speed is 1 mile per minute
rounded to the nearest tenth of a mile is
1.0 mph
Divide 30 by 10. 30mph/10seconds = 3mph/seconds
By definition, if two lines share the same gradient, they are said to be parallel. So, we know for this equation, it must have a gradient of 1/2.
Now, since the point (-6, 4) passes through the line, we know it must satisfy the equation. Since we have a gradient/slope and a point, we can use the point-gradient form:
![y - y_1 = \frac{1}{2}(x - x_1)](https://tex.z-dn.net/?f=y%20-%20y_1%20%3D%20%5Cfrac%7B1%7D%7B2%7D%28x%20-%20x_1%29)
, where
![(x_1, y_1)](https://tex.z-dn.net/?f=%28x_1%2C%20y_1%29)
represents the points being passed through.
![y - 4 = \frac{1}{2}(x + 6)](https://tex.z-dn.net/?f=y%20-%204%20%3D%20%5Cfrac%7B1%7D%7B2%7D%28x%20%2B%206%29)
![2y - 8 = x + 6](https://tex.z-dn.net/?f=2y%20-%208%20%3D%20x%20%2B%206)
![2y = x + 14](https://tex.z-dn.net/?f=2y%20%3D%20x%20%2B%2014)
The slope is (9-7)(4-(-2)) = 2/6 = 1/3;
<span> user: which of the following represents 3x - 5y 10 = 0 written in slope-intercept form???
</span>
The correct anwer for the last question is b).
