Which of the following describes the correct process for solving the equation 3x + 6 = 21 and arrives at the correct solution? D

ivide both sides by 6 and then add 3. The solution is x = 5. Add 6 to both sides of the equation and then divide by 3. The solution is x = 9. Subtract 6 from both sides of the equation and then divide by 3. The solution is x = 8. Subtract 6 from both sides of the equation and then divide by 3. The solution is x = 5.

Mrs. Smythe is twice as old as her daughter Samantha. Ten years ago the sum of their ages was 46 years. How old is Mrs. Smythe?
Fynjy0 [20]
Mrs. Smythe = x
Daughter = y

x = 2y
(x - 10) + (y - 10) = 46
x - 10 + y - 10 = 46
x + y - 20 = 46
x + y = 66
Put 2y in for x
2y + y = 66
3y = 66
y = 66/3
y = 22

The daughter is 22
The mother = 44

Antoine stands on a balcony and throws a ball to his dog, who is at ground level.
sdas [7]

Answer: The ball will hit the ground 4 seconds after being thrown.

Step-by-step explanation:

By definition, the ball hits the grounds when the height is zero.

Then, knowing that the Quadratic function that models that situation is:

h(x)=-2x^2+4x+16

You can make it equal to zero:

0=-2x^2+4x+16

Now you can use the Quadratic formula:

x=\frac{-b\±\sqrt{b^2-4ac} }{2a}

In this case you can identify that:

a=-2\\b=4\\c=16

Therefore, knowing these values, you can substitute them into the Quadratic formula and then evaluate, in order to find the solution:

x=\frac{-4\±\sqrt{4^2-4(-2)(16)} }{2(-2)}\\\\x_1=4\\x_2=-2

Choose the positive solution.

Then, the ball will hit the ground 4 seconds after being thrown.
