Determine if the equation is parallel, perpendicular, or neither;

The equations are parallel because the slopes are opposite reciprocals, which means if you flip -3/2 and multiply by -1 you get 2/3.

Solve each system of equations by graphing y=-1/2x+5 and y=3x-2
777dan777 [17]
Just make the equations equal to each other.  -0.5x+5=3x-2.  Solve for x and find that it is 2, via simple algebra.  Since you know x is 2, sub it in in either equation to find y.  y should be 4.  So the point that fits both equation is (2,4).  This shows that the two graphs of these lines will intersect at this exact point.

If you were to graph these two lines, you ould see that the point of intersection is at (2,4) like we solved for.

Thrice the difference between x and 4 is less than9 what's the inequality
3241004551 [841]
(x-4)•2 < 9
the difference between x and 4 means to subtract
and twice that means to double or times by 2
and all that’s LESS than 9
so the sign opens up towards the 9

A home Improvement store advertises 60 ft.² of flooring for 287.00 including an 80.00 installation fee write an equation to repr
anastassius [24]

Answer:

cost = \frac{287}{60} +80

Step-by-step explanation:

So, for 60 square feet they charge = 287

So, for 1 square foot they charge = \frac{287}{60}

If they charge the installation fee this becomes = \frac{287}{60} +80

We can write an equation to calculate cost by using this =\frac{287}{60} x +80

Where x is the amount of square foot
