-14n⁴ + 7n² + 8n + 7

Step-by-step explanation:

(8n - 3n⁴ + 10n²) - (3n² + 11n⁴ - 7)

= 8n - 3n⁴ + 10n² - 3n² - 11n⁴ + 7

= -3n⁴ - 11n⁴ + 10n² - 3n² + 8n + 7

= -14n⁴ + 7n² + 8n + 7

Write the equation of the circle with center (7,-2) and radius square root 61. Please show your work!

Vladimir79 [104]

The equation of a circle is (x - h)^2 + (y - k)^2 = r^2
x and y are left alone in a circle equation, while h and k are the coordinates of the center.

Thus, our equation is (x - 7)^2 + (y + 2)^2 = 61

(5x-25)+(3x+9)=180 please answer right now

jok3333 [9.3K]

Answer:

$x=24.5\\$

Step-by-step explanation:

So we have the equation:

$(5x-25)+(3x+9)+180$

Combine like terms:

$(5x+3x)+(-25+9)=180$

Add:

$8x-16=180$

Add 16 to both sides:

$8x=196$

Divide both sides by 8:

$x=24.5\\$

So, our answer is 24.5 :)

Suppose that y varies inversely with x. Use the information to find k, and then choose the equation of variation. X=2 when y=2

Vlad1618 [11]

Answer:

see explanation

Step-by-step explanation:

Given that y varies inversely as x then the equation relating them is

y = $\frac{k}{x}$ ← k is the constant of variation

To find k use the condition

x = 2 when y = 2

k = yx = 2 × 2 = 4, hence

y = $\frac{4}{x}$ ← equation of variation
