Answer:
D. Subtraction property of equality
B. 6.5
Step-by-step explanation:
First blank:
The equation is x + 6.5 = 13.
To solve the equation, you want x alone on the left side, showing "x = some number." Since 6.5 is being added to x, you need to SUBTRACT 6.5. You must do the same operation to both sides of an equation, so you need to SUBTRACT 6.5 from both sides of the equation. What allows you to subtract the same number from both sides of an equation is the
<em>D. Subtraction property of equality </em>
Second blank:
Subtract 6.5 from both sides.
x + 6.5 = 13
x + 6.5 - 6.5 = 13 - 6.5
x = 6.5
<em>Answer: B. 6.5</em>
in order to find a point on the line assume that the line cuts the y-intercept at x=0 then subsitute this value on the equation to get the value of of y at this point x=0
A. Karl
Karl has an average of 104 and Fredo only has an average of 99.6
E= 9 because you have to distribute -3.6 to E and -4
The height when the ball drops would be 0, so plug in 0 for h(t):
0 = -16t^2 + 500
Then you would solve for t, which in this case would equal to the time it takes to land.
-500 = -16t^2
t = 5.59, so it would take about 5.6 seconds to reach the ground.
