Answer:
1 kg I thik it is right ans
X is 0 so that means you answer would be 3+0=3
Answer:
60 degrees
Step-by-step explanation:
Since all three sides are the same length, all three angles must be the same size. This means the triangle is an equilateral triangle
The angles are 60 degrees
Answer:
Yes
Step-by-step explanation:
The domain is {-19, 19}
The range is {0,16}
We can write as ordered pairs to obtain:
(-19,0), (19,16)
None of the first coordinates of the ordered pairs repeats.
Hence the relation represents a function.
See attachment for mapping diagram.
C(x)=rx+s we are told that x=3, c(x)=21, and s=3
21=3r+3 divide both sides by 3
7=r+1 subtract 1 from both sides
6=r so now c(x) becomes:
c(x)=6x+3
