Answer:
No, it does not. When you enter this formula into the y- input you gut mostly a U or V shaped graph
Answer:
x=-58/15
Step-by-step explanation:
distribute first 10-2.5x+12=21-10x-28
Simplify(add the numbers) 22-2.5x=-7-10x
move the variable to the left side 22-2.5x+10x=-7
move the constant to the right side -2.5x+10x=-7-22
simplify like terms 7.5x=-29
divide by 7.5 x=-58/15
alternate forms are x=-3 13/15 or x=-3.86
Answer:

Step-by-step explanation:
Drop a height directly through the middle of the triangle, intersecting the base at a 90 degree angle. We form two right triangles and can use the Pythagorean theorem to solve for the hypotenuse.
The Pythagorean theorem states that for any right triangle, the following is true:
, where
and
are two legs of the triangle and
is the hypotenuse.
Therefore, we have the following equation (using the graph to measure the length of the two legs):

The other "tilted" side must be the same length. The base of the triangle can be measured using the graph - 10 units.
Therefore, the perimeter is 
Y= -3/4x - 5
slope intercept form is y=mx + b
the mx is your slope, in this equation -3/4
the b is the y intercept, where the line first crosses the y axis. in this equation -5.
hope this helps :)
