Answer:
The persons saves 25% by buying one set of six ball instead of two sets of three balls.
Step-by-step explanation:
Cost of 1 set of three balls = 40 cents
Cost of 2 sets of three balls = 40 cents × 2 = 80 cents
Cost of 1 set of six balls = 60 cents
Percent dose he save by buying one set of six ball instead of two sets of three balls :
=

Answer:
y=-1/2x-5
Step-by-step explanation:
First we need to put (y-3)=2(x-4) in slope intercept form.
we need to do order of operations....
so we need to first do the parenthesis
x*2= 2x
2*-4= -8
y-3=2x-8
add 3 on both sides to isolate y
y= 2x-5
so now we know the y=mx+b form
this is one line...
now we need to find out what line is perpendicular.
Perpendicular lines have opposite reciprocals slopes.
y=-1/2x-5
<span>The rocket that will reach a greater distance above the ground at its maximum height is y = -4x</span>² + 80x. The answer is letter B. This is because of the coefficient presented in the x² term. The number -4 is much greater than -6. Graphing these equations into a graphing paper or excel, you would get a parabola.
