X=-1.8
To solve first use the distributive property to change the equation to -2x+1 1/3+1=5
Then you subtract 1 from 5 so then the equation looks like this: -2x+1 1/3=4
Next subtract 1 1/3 from 4 to get 3.6
then divide it by -2 and you get -1.8
The sum of interior angels of a pentagon is 550
Answer:
Step-by-step explanation:
The total height of the building in the picture has been shown as
x + x + 6
That is, the first two storys have been shown as x feet each and the total height is 26 feet.
That means the two x are actually 20 feet, (if you deduct the 6 feet given)
Total height = x + x + 6
26 = x + x + 6
26 = 2x + 6
Subtract 6 from both sides of the equation
26 - 6 = 2x + 6 - 6
20 = 2x
Divide both sides of the equation by 2 and you now have,
20/2 = 2x/2
10 = x
Therefore, te height of each story is 10 feet!
Answer:
A function means that we get one input and one output. In this example that means for every x-value that we have, we only have one y-value.
Looking at the first option, we can see that there is no x-value that has more than one y-value which means that it is a function.
The rest of the options are seen with at least two values for one x-value in one of the points. Therefore, they wouldn't be considered a function leaving us with only option A as the solution.
