Answer:
A
Step-by-step explanation:
(-2x^3y^2+4x^2y^3-3xy^4)-(6x^4y-5x^2y^3-y^5)
-2x^3y^2+4x^2y^3-(-5x^2y^3)-3xy^4-6x^4y-(-y^5)
-2x^3y^2+4x^2y^3+5x^2y^3-3xy^4-6x^4y+y^5
-2x^3y^2+9x^2y^3-3xy^4-6x^4y+y^5
-6x^4y-2x^3y^2+9x^2y^3-3xy^4+y^5
Half of 23 would 11.5 and you had to do was divide 23 by 2
Answer:
Coefficient is 405.
Answer:
-(14 - 7x); 7(x - 2); 3x - 14 + 4x
Step-by-step explanation:
for -(14 - 7x) when the negative is distributed you get -14 + 7x which is still 7x - 14
for 7(x - 2) when multiplied in you get 7x - 14
for 3x - 14 + 4x when added together you get 7x - 14
Answer:
r = 5sec(θ)
Step-by-step explanation:
The usual conversion is ...
y = r·sin(θ)
x = r·cos(θ)
__
The second of these can be used here.
r·cos(θ) -5 = 0
r·cos(θ) = 5
r = 5/cos(θ) = 5sec(θ)
A suitable polar equation is ...
r = 5sec(θ)
