Answer:
3(1+3) = 8-2
12 = 6
therefore x is not equal to 1.
Answer:
undefined
Step-by-step explanation:
so you can just pick 2 points. use -3,0, and 2,0. so to get from -3 to 2(becusse slope is change of y over change of x) you add 5. to get from 0 to 0, you would add zero. so, 5/0=undefined. I'm not quite sure why thered 3,4. in that case it may just not be a function
Answer:
you use the foil method, which is just multiplying the first and second term in the first parentheses by the two numbers in the parentheses being multiplied.
Since <A = <D and <B = <E, it must be true that the third angles <C = <F (the triangles are similar).
If <C = x and <F = 2x-30 then you need to find x for which <C = <F is true:
x = 2x-30
and that holds for x=30
So m<C=30 degrees
You are right: the graph does not represent a proportion, because it does not go thru the origin.
