Answer:
Step-by-step explanation:
A polynomial is said to be in standard form when it is written in descending order of the given variable.
From the given polynomial
- s is written in descending power
- r is written in ascending order
Therefore, a first term of the polynomial must satisfy the following:
- Power of r must be less than 2
- Power of s must be greater than 4.
The following satisfies these conditions:
Y(hat) = 14x + 1
y(hat) = 14(12) + 1
y(hat) = 168 + 1
y(hat) = 169
Residual = y - y(hat)
12 - 169
Res = - 157

For problem 4; start with clue 2, then clue 3, then clue 4, and lastly do clue 4.
<u>Clue 2</u>
3 · square - 8 = 19
3 · square = 27 <em>added 8 to both sides</em>
square = 9 <em>divided both sides by 3</em>
<u>Clue 3</u>
2 · triangle + 3 = -3
2 · triangle = -6 <em>subtracted 3 from both sides</em>
triangle = -3 <em>divided both sides by 2</em>
<u>Clue 4</u>
square + triangle = 6
(9) + (-3) = 6 <em>substituted solutions from Clue 2 and Clue 3</em>
6 = 6 <em>True statement confirms that Clues 2 & 3 are correct</em>
<u>Clue 1</u>
star + square = 12
star + (9) = 12 <em>substituted solution from Clue 2 </em>
star = 3 <em>subtracted 9 from both sides</em>
Answer: triangle = -3, star = 3, square = 9
For problem 5; do the same thing as problem 4 and start with Clue 2
Answers: triangle = -2, star = 10, square = 8
Answer:
k^2 = 90
k= 9.486

Technically yes they can be, but you won't get a whole number for all of them. To get a whole number only 3, 5, and 9 would be used.
