Answer:
Step-by-step explanation:
If x is -1, then the point on the parabol is (-1,4)
If x is 0, then the point on the parabol is (0,-2)
If x is 1, then the point on the parabol is (1,-6)
The "system" of equations can't be solved for (x, y), because there's no "system" of equations given. There's really only one equation.
Either of these two equations can be massaged to look exactly like the other one. And if you graph both equations, you find that they're both the same line on the graph.
ANY point on the line is a solution to both equations ... and we all know how many different points there are on a line.
Answer:
Is a consistent independent system
Step-by-step explanation:
we have
-----> isolate the variable y
----> equation A
-----> isolate the variable y
---> equation B
Compare equation A and equation B
We can affirm that
The slopes are not equal ( so the lines are not parallel)
The lines are different
The product of their slopes is equal to -1 (the lines are perpendicular)
so
The system of equations has only one solution
therefore
Is a consistent independent system
STEP 1
find cubic feet; multiply the three dimensions together; be sure to use the same unit of measure for all three dimensions: 6 inches is equal to 1/2'.
= 38' * 37' * 1/2'
multiply
= 703 cubic feet
STEP 2
divide cubic feet in step 1 by number of cubic feet in a cubic yard
27 cubic feet= 1 cubic yard
= 703 ÷ 27
= 26.037 cubic yards
STEP 3
multiply cubic yards in step 2 by cost per cubic yard
= 26.037 * $150
= $3,905.555
= $3,906 rounded to nearest dollar
ANSWER: It will cost $3,906 (rounded to nearest dollar).
Hope this helps! :)
