2x-y=1 is also equal to y=2x-1 so then plug in 1 or x and so on to create a table
Let
x---------> first positive integer
x+1------> second positive integer
x+2-----> third positive integer
we know that
(x+1)*(x+2)=72-------> x² +2x+x+2=72 -------> x² +3x-70=0
using a graph tool-------> <span>I solve the quadratic equation
</span>see the attached figure
the roots are
x1=-10
x2=7
the answer is
first positive integer is x=7
second positive integer is x+1=8
third positive integer is x+2=9
Answer:
C) x/2 +2y = 4
Step-by-step explanation:
Of the equations offered, only equation C has the given point as a possible solution.
___
Since the graph is not given, we don't know if the given point is on the graphed equation.
That is how you graph y=2/5x+2 since 2/5 is the slope and 2 is the y intercept.
Answer:
I think it's A.
