Answer:
a. y = x + 3
Step-by-step explanation:
All three ordered pairs satisfy the first equation.
___
If you want to look into it a little further, you can notice that if you sort the ordered pairs by their x-values, you get ...
(-1, 2), (0, 3), (1, 4)
That is, the y-values increase (by 1) as the x-values increase (by 1).
All of the other answer choices have -1 as the coefficient for x, which means the y-values will decrease as x increases. None of these choices (b–d) is viable.
15x = 30
x = 30/15
x = 2
Easy =)
The answer for the exercise shown in the figure attached is shown below:
1- side lengths.
2- a^2+b^2=c^2
3- is a rigth triangle
Therefore, in other words, you can know that a triangle is a rigth triangle (which means that it has an angle of 90 degrees) when the square of its longest side is equatl to the sum of the squares of the other sides.
Answer:
It proves that a||b because they are corresponding externally.
4 and 5 are the only constant terms in that expression.
