Let the three sides be: x, %28x%2B2%29, %28x%2B4%29
then the perimeter:
p+=+x+%2B+%28x%2B2%29+%2B+%28x%2B4%29
p+=+3x+%2B+6
- the longest side is it is 22 units shorter than the perimeter, so you will have
%283x%2B6%29+-+%28x%2B4%29+=+22
3x+%2B+6+-+x+-+4+=+22
2x+%2B+2+=+22
2x+=+22+-+2
2x+=+20
x+=+10, ........the shortest side
then
10+%2B+4+=+14 units is the longest side
Using function concepts, it is found that:
- The domain is: {0, 1, 2, 3, 4, 5, 6}
- The range is: {0, 0.25, 0.5, 0.75, 1, 1.25, 1.5}.
-----------------------------
- The domain of a data-set is the set that contains <u>all possible input values.</u>
- The range of a data-set is the set that contains <u>all possible output values.</u>
-----------------------------
- The data-set is (n, 0.25n), in which the <u>input is the number of quarters n</u>, and the <u>output in the amount in dollars</u>, which is 0.25n, as each quarter is worth $0.25.
- Up to $1.50, thus at most 6 coints, as
Thus means that:
- The domain is: {0, 1, 2, 3, 4, 5, 6}
- The range is: {0, 0.25, 0.5, 0.75, 1, 1.25, 1.5}.

Answer:
d
Step-by-step explanation:
Solution by substitution method
y=7x+8
∴y-7x=8
and y=x+20
∴y-x=20
Suppose,
-7x+y=8→(1)
and -x+y=20→(2)
Taking equation (1), we have
-7x+y=8
⇒y=7x+8→(3)
Putting y=7x+8 in equation (2), we get
-x + 7x + 8 = 20
6x = 20-8
6x = 12
x= 12 / 6
x = 2
substitute for x in equation (3)
y = 7(x) + 8
y = 7(2) + 8
y = 22
