Answer:
They are both linear
Step-by-step explanation:
1.
Use rise/run to find the slope of the line.
rise=21.8
run=1
therefore, the slope is 1/28. You can use that to graph the line. If the line meets the points on your table, it is linear. It does. The equation of the line would be y=21.8x.
2.
We can use the same process as before.
rise=7
run=2
Therefore, slope is 7/2. When this line is graphed it meets all the points, so it is linear.
Alteratively, you could graph the points first and then see if you get the same slope.
The correct option about squaring the binomial is that B. The student is wrong. There is a missing term.
<h3>How to use binomial theorem?</h3>
We want to square a binomial and using pascal's triangle in binomial theorem, we know that; (x + a)² will follow the pattern;
1x²a⁰ + 2a¹x¹ + 1x⁰a²
Thus, we can say that the expression (x + 3)² will give us;
x² + 2(3x) + 9a²
= x² + 6x + a²
Thus, we can say that the correct option about squaring the binomial is that B. The student is wrong. There is a missing term.
Complete Question is;
A student is instructed to square a binomial, and gets the result shown. Choose the correct description of the student's work. (x + 3)² = x² + 9 Choose the correct answer below.
A. The student is wrong. You cannot square a binomial, only monomials.
B. The student is wrong. There is a missing term.
C. The student is correct. Each given term is squared.
D. The student is wrong. The student should add the threes instead of multiplying them.

Answer:
5x+10
Step-by-step explanation:
let f(x)=(x-10)/5=y
now write 'x' in term of y
i.e, x-10=5y
i.e, x=5y+10
now replace y with x to get required inverse of f(x)
=5x+10
