Answer:

11x^2y^3 - 4xy^2

Step-by-step explanation:

(4x^2y^3 - 2xy^2 - 2y) - (-7x^2y^3 + 6xy^2 - 2y)

Combine like terms

4x^2y^3 - -7x^2y^3 = 11x^2y^3
Two negative signs together makes addition!

Combine like terms

2xy^2 - 6xy^2 = -4xy^2

Combine like terms

-2y - 2y = 0
We don’t have to include the zero

Now add 11x^2y^3 with -4xy^2 together

11x^2y^3 - 4xy^2

Therefore, the answer is: 11x^2y^3 - 4xy^2

2x + 3 = 4x^2<br> completing the square
ch4aika [34]

Answer:

\frac{1+\sqrt{13} }{4}, \frac{1-\sqrt{13} }{4}

Step-by-step explanation:

First, make them on one side of the formula in the form of ax^2+bx+c=0 which is 4x^{2} -2x-3=0

Next, insert the corresponding number in the quadratic formula, \frac{-b+\sqrt{b^{2}-4ac } }{2a}  ,\frac{-b-\sqrt{b^{2}-4ac } }{2a} , and the answer can be calculated.

Determine the equation of a circle with a center at (–4, 0) that passes through the point (–2, 1) by following the steps below.
GaryK [48]

Answer:

Radius length: √5

Standard Form (Equation): (x + 4)^2 + y^2 = 5

Step-by-step explanation:

First we will determine the radius;

Center: (-4, 0)

Point on Circumference: (-2, 1)

d = √(-2 - (-4))^2 + (1 - 0)^2 = √(2)^2 + (1)^2

= √4 + 1 = √5

Therefore the radius is of length √5

Now the equation of a circle is in the form ((x - h)^2 + (y - k)^2) = r^2. The center is in the form (h,k) and r is the radius. Given this our equation would be (x - (-4))^2 + (y - 0)^2 = (√5)^2, or [simplified] (x + 4)^2 + y^2 = 5.
