Answer:
2,100
Step-by-step explanation:
$200 * 3.5= $700
$700 * 3= $2,100
Answer:
A: 9x-3y =5
Step-by-step explanation:
slope of the line = (8-(-1))/(-1)-(-4) = 3
so y = mx+ c , where m= slope
the equation 9x-3y= 5 has the slope 3 since we can make y the subject of the formula to get
y= 3x - 5/3..here m is also equal to 3
You first have to set up the two equations. Y is equal to the total number of gallons in a tank and x is equal to the number of hours the tanks are filling.
Since the two equations both equal y I can make them equal each other. I then solved for x as you see and got -4.
Once I found my x value I now needed to find my y. You only needed to chose one equation to solve for y, so I decided to do the first one. I plugged in -4 where my x value currently was and solved for y. I got 2.
If you have any questions please comment!! Hope this helps!!
To find slope, use the form y1 - y2/x1 - x2. Using these points, that would look like:
-7 - 5/-1 - 1 or -12/-2, which simplifies to 6.
The slope is 6. Hope this helps with slope.
A simple diagram will show you the intersection of altitudes is in the 2nd quadrant. It must have x-coordinate -2, as the altitude to the "base" y=10 must be the vertical line through (-2, 4).
The appropriate choice is ...
... C: (-2, 12)
