Answer:
21 2
33 3
44 4
Step-by-step explanation:
think of them as equivalent fractions
Answer:
2
Step-by-step explanation:
The temperature was originally 2 degrees because if you draw a number line and put a 0 in the middle of the positive numbers and the negative numbers ( - 8 - 7 - 6 -5 - 4 0 1 2 3 4 5 6 7 8) - example. Put the positive and negative numbers on different sides of the 0 and go left from the positive numbers from 2 and count 6 skips down to - 4. So 2 would be your answer.

Seems like "6x+5=4x+5" has only one solution that's 0.
Answer:
116
Step-by-step explanation:
3 to the power of 4 is 81. 7x5 =35+81=116
<u>ANSWER</u>
The zeros are ![x=-5,x=0,x=5](https://tex.z-dn.net/?f=x%3D-5%2Cx%3D0%2Cx%3D5)
EXPLANATION
Given;
.
We can rewrite the function as
![f(x)=x^2(x^2-25)](https://tex.z-dn.net/?f=f%28x%29%3Dx%5E2%28x%5E2-25%29)
![\Rightarrow f(x)=x^2(x^2-5^2)](https://tex.z-dn.net/?f=%5CRightarrow%20f%28x%29%3Dx%5E2%28x%5E2-5%5E2%29)
![\Rightarrow f(x)=x^2(x-5)(x+5)](https://tex.z-dn.net/?f=%5CRightarrow%20f%28x%29%3Dx%5E2%28x-5%29%28x%2B5%29)
The zeros are found by equating the function to zero.
![\Rightarrow x^2(x-5)(x+5)=0](https://tex.z-dn.net/?f=%5CRightarrow%20x%5E2%28x-5%29%28x%2B5%29%3D0)
![\Rightarrow (x-5)=0](https://tex.z-dn.net/?f=%5CRightarrow%20%28x-5%29%3D0)
The multiplicity is 1, since it is odd the graph crosses at this intercept. which is ![x=5](https://tex.z-dn.net/?f=x%3D5)
Or
![\Rightarrow (x+5)=0](https://tex.z-dn.net/?f=%5CRightarrow%20%28x%2B5%29%3D0)
The multiplicity is 1, since it is odd the graph crosses at this intercept. which is ![x=-5](https://tex.z-dn.net/?f=x%3D-5)
Or
![\Rightarrow x^2=0](https://tex.z-dn.net/?f=%5CRightarrow%20x%5E2%3D0)
This last root has a multiplicity of 2.
That is
repeats two times.
Since the multiplicity is even, the graph touches the x-axis at the point
