Answer:
h = 16
Step-by-step explanation:
to solve this equation
we are going to take cognizance of the positive and negative sign as any misinterpretation of the sign might influence our answer wrongly. Note this
negative × negative = positive
positive × negative = negative
negative × positive = negative
positive × positive = positive
so, from the question 19 - h - h = -13
19 - h - h = -13
19 -2h = -13
collect the like terms
19 + 13 = 2h
32 = 2h
divide both sides by the coefficient of h which is 2
32/2 = 2h/2
16 = h
therefore h = 16
Let P (x,y) be any point on the x-axis. Then clearly, for all position of P we shall the same ordinate 0 or, y = 0. Therefore, the equation of x-axis is y = 0. If a straight line is parallel and below to x-axis at a distance b, then its equation is y = -b.
those are the vertex form of a parabola... so hmmm
the vertex of this one is at 0,1 and intercepts or "solutions" are at -1 and 1, so is opening downwards, notice the picture below
that means, the squared variable is the "x", thus the form is
now, we know the vertex is at 0,1, and two x-intercepts of
thus
solve for "a", to see what that coefficient is, then plug it back in the vertex form equation
