Answer:

Step-by-step explanation:
A polynomial is given to us and we need to make the polynomial by its degree . Here the given polynomial is 3x² + 5x -3 .

So here we can see that the highest power of the variable in the given polynomial is 2 . So the polynomial is a quadratic polynomial .
<u>★</u><u> </u><u>More </u><u>to </u><u>Know </u><u>:</u><u>-</u>
When we equate this quadratic polynomial with 0 , it becomes a quadratic equation.
That is ,
This is done in order to find the zeroes of the polynomial. The zeroes of the polynomial are the values for which the polynomial becomes 0 .
This is a system of equation:
7y - 5x = 31
x = 4 - 2y
Plug in 4 - 2y for x
7y - 5(4 - 2y) = 31
Distribute -5 to both 4 and -2y
7y - 20 + 10y = 31
Simplify
17y - 20 = 31
Isolate the y. Note the equal sign. What you do to one side you do to the other. Do the opposite of PEMDAS.
Add 20 to both sides
17y - 20 (+20) = 31 (+20)
17y = 51
Divide 17 from both sides to isolate the y
17y/17 = 51/17
y = 51/17 or 3
y = 3
-------------------------------------------------------------------------------------------------------------------
Plug in 3 for y in one of the equations.
x=4−2y
x = 4 - 2(3)
Simplify.
x = 4 - 6
x = -2
-------------------------------------------------------------------------------------------------------------------
x = -2, y = 3 is your answer, or B)

Answer:
9 squirrels and 36 birds
Step-by-step explanation:
4x+x=45
5x=45
x=9
4*9=36
Last choice cuz look at the graph
<h2>
Answer:</h2>
x = 37
<h2>
Step-by-step explanation: </h2>
x + x = 74
2x = 74
divide both sides by 2 which is
x = 37
