Answer:
1
Step-by-step explanation:
Anything to the zero power is 1
7^0
1
Its 60 all you really had to do is 6 times 10
Answer:
You would do this problem like a normal varible problem. x=10
Step-by-step explanation:
Since 9x is a right angle the inside would also be 9x
9x+4x+10+40=180
180 because that is how much a triangle equals
combine like terms
13x+50=180
subtract 50 from both sides
13x=130
divide by 13
x=10

Determine which system of equation satisfy (-4,2)
To do this, we simply substitute -4 for x and 2 for y in the given functions.
A.
and
![3x + 13y = 14](https://tex.z-dn.net/?f=3x%20%2B%2013y%20%3D%2014)
![3(-4) + 13(2) = 14](https://tex.z-dn.net/?f=3%28-4%29%20%2B%2013%282%29%20%3D%2014)
![-12 + 26 = 14](https://tex.z-dn.net/?f=-12%20%2B%2026%20%3D%2014)
![14 = 14](https://tex.z-dn.net/?f=14%20%3D%2014)
![6x + 11y = -2](https://tex.z-dn.net/?f=6x%20%2B%2011y%20%3D%20-2)
![6(-4) + 11(2) = -2](https://tex.z-dn.net/?f=6%28-4%29%20%2B%2011%282%29%20%3D%20-2)
![-24 + 22 = -2](https://tex.z-dn.net/?f=-24%20%2B%2022%20%3D%20-2)
![-2 = -2](https://tex.z-dn.net/?f=-2%20%3D%20-2)
The above shows that the given linear combination has a solution of (-4,2).
<em>Hence, this option answers the question and there is no need to check other options</em>
