1. Conversion: 0.001 = 1/1000
2. Multiple: 10 * 0.001 = 10 · 11 · 1000 = 101000 = 1100
Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(10, 1000) = 10
3. Subtract: 1100 - 3 = 1100 - 31 = 1100 - 3 · 1001 · 100 = 1100 - 300100 = 1 - 300100 = -299100
The common denominator you can calculate as the least common multiple of the both denominators - LCM(100, 1) = 100
4. = (-299/100)

Need help on 9 and 10

Wewaii [24]

9.) The relation can not be a function only if the domain is the same. If you plot the points on a graph and use the Vertical Line Test(VLT) you would see that none of the points would be on the same line. It doesn't matter if the range is the same

10.)On the graph your y-intercept would be 2 so that is where you plot your first point. In order to find the slope you need to go up three spaces and one space to the left this is also known as "rise over run". *Remember you always go up spaces for "rise over run" but if the slope is positive then you go to the right and if its negative you go to the left.

I hope this helps love! :)
