Answer:
t=1.58 seconds
Explanation:
The equation which models the height <em>h</em><em> </em>of the seashell above water after t seconds
Make an equation for each statement with x being catcher's mitts and y being outfielder's gloves.
x + 10y = 239.50 and x + 5y = 134.50
Multiply the second equation through by -1 giving -x - 5y = -134.50
Combine the equations vertically
x + 10y = 239.50
-x - 5y = -134.50
giving
5y = 105
y = 21
Now substitute for y:
x + 10(21) = 239.50
x + 210 = 239.50
x = 29.50
Thus, Catchers mitts $29.50 and outfielder's gloves are $21
The answer is 25m.
Height = 15
Length = 25
Height+lengthx2= 80(perimeter)
Height x length=375m2(area)
Written in 2-point form, the equation of the line is
y = (y2-y1)/(x2-x1)·(x-x1) +y1
y = (3-(-5))/(-6-(-4))·(x-(-4)) + (-5)
y = 8/-2·(x +4) - 5
y = -4x -21
The value of b is -21.
