Answer:

This is the associative property.

Step-by-step explanation:

The only operation in this expression is multiplication.

We know that the order in which we multiply numbers does not change their product; therefore we can group different numbers together and get the same product.

In this case, on the right hand side, 3 and 4 are grouped together first, then multiplied by 6. This gives us 12*6 = 72.

On the left hand side, 4 and 6 are grouped together first, then multiplied by 3. This gives us 24*3 = 72.

<span>-4x + y = -25 y = 4x - 25

-6x - 6y = 0 </span>

-6x - 6(4x - 25) = 0
-6x - 24x + 150 = 0
-30x + 150 = 0
-30x = -150
x = 5

y = 4(5) - 25
y = 20 - 25
y = -5

Answer:

maximum height of 17.07 feet about 10.67 feet from the club

returns to the ground 21.33 feet away

Step-by-step explanation:

A graphing calculator can answer these questions easily.

The vertex of the quadratic ax²+bx+c is given by x=-b/(2a). For this quadratic function, the highest point is found at ...

x = -(3.2)/(2(-0.15)) = 32/3 = 10 2/3 . . . . feet horizontally from the club

The maximum height is the function value at that point.

h(10 2/3) = (-0.15(10 2/3) +3.2)(10 2/3) = 1.6(10 2/3) = 17 1/15

The ball reaches a maximum height of 17 1/15 feet at a horizontal distance of 10 2/3 feet from the club. The ball's flight is symmetrical about the peak, so it returns to the ground about 21 1/3 feet away.
