The expressions 3x² - 7y, 2 - 8y, 4x² - 9 are polynomilas.
What is apolynomial?A polynomial is an algebraic expression of degree n where n belongs to whole numbers.
A polynomial of degree n can be written as a₀xⁿ + a₁xⁿ⁻¹ + a₂xⁿ⁻² + ... + aₙ.
Given, are 4 polynomials 3x² - 7y it is a polynomial because it has powers that are in whole numbers and it is of degree 2 in variables x and y.
2 - 8y is also a polynomial as the degree of y is 1 and it is a whole number.
3x⁻² + y is not a polynomial as the degree of x is - 2 and it is not a whole number.
4x² - 9 is also a polynomial as it has a degree of 2 a whole number.

he two In a class of 60 students, 46 passed Biology
and 42 passed Chemistry. Every student
ariable passed at least one of the two subjects. How
many students passed in both subjects?
Solution
Let U = students in the class
cps
Answer:
28 students passed in both subjects.
Step-by-step explanation:
We solve this question treating each event as a Venn set.
I am going to say that:
Event A: Passed Biology.
Event B: Passed Chemistry.
46 passed Biology
This means that [tex]A = 46[/tex]
42 passed Chemistry.
This means that [tex]B = 42[/tex]
Every student passed at least one of the two subjects.
This means that [tex]A \cup B = 60[/tex]
How many students passed in both subjects?
This is:
[tex]A \cap B = A + B - A \cup B[/tex]
From the values we have above
[tex]A \cap B = 46 + 42 - 60 = 28[/tex]
28 students passed in both subjects.

Given f(x)=0.25(6)x, find f−1(x).
Answer:
f−1(x) = [tex]\frac{4x}{6}[/tex]
Step-by-step explanation:
f(x) = 0.25(6)x, find f−1(x).
f(x) = 0.25(6)x
f(x) = [tex]\frac{6}{4}[/tex]x = [tex]\frac{6x}{4}[/tex]
f(x) = y
y = [tex]\frac{6x}{4}[/tex]
Substitute y for an x & x for a y
x = [tex]\frac{6y}{4}[/tex]
Multiply both sides by 4
4( x ) = 4( [tex]\frac{6y}{4}[/tex] )
4x = 6y
Divide both sides by 6 to solve for y
[tex]\frac{4x}{6}[/tex] = y
y = [tex]\frac{4x}{6}[/tex]
so f−1(x) = [tex]\frac{4x}{6}[/tex]

3 ⅕ -⅔ divided by 2 ⅘
Answer:
160/196
Step-by-step explanation:
it would be easier if you converted all fractions to improper fractions
so 3 1/5 would equal 16/5 and 2 4/5 would equal to 14/5
[tex]\frac{14}{5} - \frac{2}{3}[/tex] : to solve this you would need the same common denomenator,
to do this you can multiply 5 and 3 by something to make the lowest common denominator, which would be 15
thus
multiplying first fraction by 3 and the second by 5
42/15 - 10/15 = 32/15
now 32/15 divided by 14/5
the rule for dividing fractions, is flipping the fraction which you will be using to divide, and then multiplying it to the first fraction:
[tex]\frac{32}{14}[/tex] multiplied by [tex]\frac{5}{14}[/tex]
thus, answer is 160/196
