1. Start with y=sx+m and input the slope of the line given, because the two lines are parallel they have the same slope. Then input the X and Y coordinates of point X to get 10=-1/2-5+m and finally solve the equation to get m=-7.5 or -15/2 making slope intercept form Y=-1/2-5-15/2
2. Follow the same instructions imputing 1/2 in as the slope because it is perpendicular to the line. so you get 10=1/2-5+m. solve to get m=7.5 or 15/2 making the final equation Y=1/2X+15/2
First, multiply the first equation by 3 to get:
Then, add the two equations together to get
We can follow that x=2. Plugging in x=2, we get that y=-4.
Therefore, the solution of (2,-4)
To do this you have to round the 3. It is the same things as asking to round to the ones place.
To the right of the 3, is a 1. Since this digit is not bigger than a 5, the 3 stays the same.
Your answer is 3
Answer:
C
Step-by-step explanation:
In five minutes it decreased by 10 gallons (5x2=10), In 10 minutes it decreased by 20 gallons.
It's a good idea to get into the habit of using <u>parentheses</u> when substituting numbers in for variables.
Since <em>a = -3</em> and <em>x = 3</em>, 5a - x is 5(-3) - (3).
5(-3) is -15 and we have (-15) - 3 which simplifies to -18.
