For what value of c is the relation a function: (2,8),(12,3), (c,4), (-1,8), (0,3)?
Answers
It seems to me c could be any number besides 2,12,-1 or 0
why?
a function is defined by each x value having a single y value
if an x value has two numbers such as (0,1) (0,2) than it is not a function.
the vertical line test is great for seeing if something is a function becasue it determines if each x value has one y value.

The side lengths form a triangle that is similar to triangle ABC will be 30, 21, and 45. Option A is correct.
What is the triangle?
In terms of geometry, a triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.
It is found that the sides of the triangle are,
AB=10
BC=7
CA=15
In order for the triangle to similar the ratio of their sides is equal.
AB:BC: CA = 10:7:15
The ratio is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.
AB:BC: CA = 10×3:7×3:15×3
AB:BC: CA =30, 21, 45
The ratio of the triangle for the given condition must be the same.
Thus, the side lengths that form a triangle that is similar to triangle ABC will be 30, 21, and 45. Option A is correct.

The final result is: x = -3.
Ok. First you isolate the variable. So Ill take 12 which is posotive, and subtract 12 from the 15 and the 12. Now all were left with is -x=3. We multiply each side by -1 to give us x=-3. Hope this helps!
