Answer:
x = 40
Step-by-step explanation:
Adding 23 to both sides gives us:
x - 23 + 23 = 17 + 23
x = 40
Answer:
AAS
Step-by-step explanation:
The first A:
∠ABC ≅ ∠DCB
The S:
CB ≅ BC
The second A:
∠A ≅ ∠D
All of them combined to prove ΔABC ≅ ΔDCB through ASA.
Initial:

Changed to:

As you can see the change is: from -1 to +6.
In a equation as follow:

The k is a transformation that moves up or down the graph of the function. If k is changed to a less value the graph moves down, If k is changed to a greather number the graph moves up.
In this case the graph moves up
To find the number of units the graph moves find the difference betwwen values of k:

Then, the parabola y=x²-1 is moved 7 units up when it is changed to y=x²+6
12:7*2=24:14
The radio is of 12:7 is 14:14
