Answer: #10 is right angles
Step-by-step explanation: because that is the sign for a right angle
Answer:
? = 49
Step-by-step explanation:
To solve this we just need to understand that when A=1, B=7. So when the side for a is 7 that is basically multiplying A by 7 so we have to do the same to the B side. So when the B side is multiplied by 7 it would be 7*7 =49 so the ? is equal to 49 when that similar side is equal to 7.
This is all based on the fact that the two triangles must be similar triangles.
Answer: (8, -4)
Step-by-step explanation:
The answer to the solution is:
X= 7
Initial:
![y=x^2-1](https://tex.z-dn.net/?f=y%3Dx%5E2-1)
Changed to:
![y=x^2+6](https://tex.z-dn.net/?f=y%3Dx%5E2%2B6)
As you can see the change is: from -1 to +6.
In a equation as follow:
![y=x^2+k](https://tex.z-dn.net/?f=y%3Dx%5E2%2Bk)
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:
![6-(-1)=7](https://tex.z-dn.net/?f=6-%28-1%29%3D7)
Then, the parabola y=x²-1 is moved 7 units up when it is changed to y=x²+6
