Answer:

3, –2, –7, –12, ...

Step-by-step explanation:

f(n+1) = f(n) − 5

This means each term is 5 less than the term before it.

The only option that works is the third one.

use the distance formula to find the distance between the two points. (0, -2) and (9, 10) give the exact length (leave in radica

kkurt [141]

Answer:

15 units

Step-by-step explanation:

Calculate the distance d using the distance formula

d = $\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }$

with (x₁, y₁ ) = (0, - 2) and (x₂, y₂ ) = (9, 10)

d = $\sqrt{(9-0)^2+(10+2)^2}$

= $\sqrt{9^2+12^2}$

= $\sqrt{81+144}$

= $\sqrt{225}$

= 15

$\dfrac{c^2-4}{6c^4+15c^3}\div\dfrac{c^2+4c+4}{12c^3+30c^2}=\dfrac{c^2-2^2}{3c^3(2c+5)}\div\dfrac{c^2+2(c)(2)+2^2}{6c^2(2c+5)}\\\\_{\text{use}\ a^2-b^2=(a-b)(a+b)\ \text{and}\ (a+b)^2=a^2+2ab+b^2}\\\\=\dfrac{(c-2)(c+2)}{3c^3(2c+5)}\cdot\dfrac{6c^2(2c+5)}{(c+2)^2}=\dfrac{(c-2)}{c}\cdot\dfrac{2}{(c+2)}=\boxed{\dfrac{2(c-2)}{c(c+2)}}$

Y+x=1 show whether x and y show direct variation <br><br><br>plzz helpp

Thepotemich [5.8K]

Answer:

Step-by-step explanation:

Please write: "Determine whether y+x=1 shows direct variation."

No, it does not, because of the constant term, 1.

If we were to eliminate the 1 and write y + x = 0, then yes, this would represent direct variation.
