Angle ADB is a right angle --- Given

Angle ADB is 90 degrees --- Definition of a Right Angle

Angle CDB is 90 degrees --- Definition of Supplementary Angles

Angle ADB = Angle CDB --- Definition of Congruent Angles

Proofs can be tricky! What helps me is thinking through them step by step and how I would prove I did something. While I'm not entirely sure what options you have for this proof, I've given my best guess.

Hope this helps!! :)

If the original function () = 22 − 1 is shifted to the left 3 units to make the
Rom4ik [11]

A horizontal translation is expressed by transforming

f(x)\mapsto f(x+k)

If k is positive, the function is translated to the left. If k is negative, the function is translated to the right.

So, a 3-units left shift is given by k=3. So you have

f(x)=2x^2-1 \implies f(x+3)=2(x+3)^2-1

Create an equation to solve for x, then solve to find its value.
Amanda [17]

Answer:

Equation: x + 16 + 13 + x = 21 ; x = -4

Step-by-step explanation:

x + 16 + 13 + x = 21 (Given)

2x + 29 = 21 (Added like terms)

2x = -8 (Subtracted 29 on both sides)

x = -4 (Divided 2 on both sides)

Mars2501 [29]

Answer:

Kyle's house is 5000 m away from the school.

Step-by-step explanation:

Carter lives 3 kilometers away from the school and Kyle lives 2000 meters farther away from the school then Carter does.

Simply put, Kyle lives an extra 2000 meters plus the distance of Carter's house from the school.

So, we simply need to add the two distances given to us to the find our answer.

Let us put the distance of Carter's house in metres:

1 km = 1000 m

=> 3 km = 3 * 1000 m = 3000 m

Hence, the distance of Kyle's house from the school is:

3000 m + 2000 m = 5000 m

Kyle's house is 5000 m away from the school.
