Answer: Let's say the first number is x, the next one is x+1, and so on
Step-by-step explanation:
x + (x + 1) + (x + 2) = -51
x + x + 1 + x + 2 = -51
3x + 3 = -51
3x = -54
x = -18

Step-by-step explanation:
A graphing calculator is useful for this.
The region of interest is below the parabola and above the line.
For a relation to be function, every x value should have its unique image in co-domain. If x is related to more than one y value, then that relation is not a function
In 1, as you can see, 1 related to -7 as well as 8. Which means 1 has two images viz. -7 and 8. But for a relation to be function, x should have only one image. Thus, it is not a function.
The worst is the 4th one in which -2 has 4 images.
Therefore, only relation B is a function.
Answer:

➳ These equations will have <u>infinite solutions</u> because they are in 2 variables. Any value can be substituted in the place of the variables x & y.
