Answer:
hello your question is incomplete attached below is the complete question
answer : 54 m
Step-by-step explanation:
Applying jet equation of Parabola
(x-h)^2 = 4p (y-k) where (h,k) = 0
x^2 = 4py and this passes through ( 48, 24 )
(48)^2 = 4(p)(24)
hence P = 24
x^2 = 96h at x = 72 and y(h) unknown
= 72^2 = 96(h)
h = 72^2 / 96 = 54 m

An equation is formed of two equal expressions. There is no solution set of the equation 3x+13 = 3(x+6)+1.
<h3>What is an equation?</h3>An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The equation can be solved in the following manner,
Since both the sides of the equation are the same in terms of variable and the constant terms are not the same. Therefore, there is no solution set of the equation 3x+13 = 3(x+6)+1.

Answer:
(x, y) = (3, 5)
Step-by-step explanation:
To solve these equations graphically, you plot each one, then identify the coordinates of the point of intersection.
The first equation can be graphed using the y-intercept of -1 and the slope of 2.
The second equation has a y-intercept of 18/3 = 6, and a slope of -1/3. The x-intercept of 18 is off the chart, so the slope and intercept are a good way to plot this line, too.
__
The slope is the "rise" divided by the "run". A slope of 2 means the line goes up 2 units for each unit to the right. A slope of -1/3 means the line goes down 1 unit for each 3 units to the right.
The solution is (x, y) = (3, 5).
