Answer:
-16 (t+3) (t-3)
Step-by-step explanation:
5x + y = 9....multiply by 7
10x - 7y = -18
----------------
35x + 7y = 63 (result of multiplying by 7)
10x - 7y = -18
----------------add
45x = 45
x = 45/45
x = 1
5x + y = 9
5(1) + y = 9
5 + y = 9
y = 9 - 5
y = 4
solution is : (1,4)
=========================
-4x + 9y = 9
x - 3y = -6 ....multiply by 4
----------------
-4x + 9y = 9
4x - 12y = -24 (result of multiplying by 4)
---------------add
- 3y = - 15
y = -15/-3
y = 5
x - 3y = -6
x - 3(5) = -6
x - 15 = -6
x = -6 + 15
x = 9
solution is : (9,5)

What are the coefficients in the polynomial 4x²+3x-3?

<u>Coefficient:-</u> A number before a variable
<u>Coefficients in this polynomial:-</u>
4 (the number before x²) and 3 (the number before x)
<h3 />
So we conclude that the right option is:-
4, 3 (Option B)
<h3>Good luck.</h3>

Hope i understand it right
9y^2 -12y^4 = 3y^2 *(3 - 4y^2)
If your asking what d equals, then it’s 10
