DE//AB, apply the Thales theorem, you have:
DC/AC = EC/BC
or
DC = (EC x AC)/BC
=> Option A is correct

Hello!
Slope intercept form is y = mx + b, where m is the slope and b is the y intercept.
Now, we first can find the slope. We know the line is parallel to y = 2/5x - 2, and parallel lines <u>always have the same slope.</u> Therefore, we now know that the slope (or m) is 2/5. Substitute that in the equation.
y = 2/5x + b
Finally, we are given a point. We can substitute (-5, -3) into the equation, and then solve for b.
x = -5, y = -3
-3 = 2/5 (-5) + b
-3 = -2 + b
-1 = b
Now, we know what b is. Substitute this into the equation.
Therefore, y = 2/5x - 1 is our final equation.
Hope this helps!
The given equation is 4x^2=x^3+2x.
On the left side it has 4x² and on the right side the expression is x³+2x.
So, if we have any system of equations in which we have these two expression which will be equal to any other variable then we can use that system of equations to find the roots.
Now notice that in option D it's given,
y=4x² and y=x³+2x.
So, if we will equate this equations then we will get the same above equation which will be use to find the roots.
So, D is the correct choice.
Answer:
15 1/12 feet
Step-by-step explanation:
Well if he descended 8 1/3 feet below the water, that means he must've went from board to water which is 6 3/4 feet then down 8 1/3 feet
6 3/4 + 8 1/3
= 6 9/12 + 8 4/12
=15 1/12 feet
