What is the slope of (-12,-12) and (9,-9)
telo118 [61]

Step-by-step explanation:

Slope, which is the same as gradient, is equal to

change in y axis ÷change in x axis

<h3>slope =  \frac{change \: in \: y}{change \: in \: x}</h3>

Our coordinates are (-12,-12) and (9,-9)

In (-12,-12),let the first -12 be <em>x1</em><em> </em>and the second one be <em>y1</em>

Same goes for the (9,-9), let 9 be <em>X2</em><em> </em>and -9l be <em>y2</em>

<em>slope =  \frac{y2 - y1}{x2 - x1}</em>

<em>=  - \frac{ - 9 -  - 12}{9 - 12}</em>

<em>=  \frac{3}{21}</em>

<em>=</em>0.1428571429

= 0.1429

Which of the following is a true polynomial identity?
Ira Lisetskai [31]

Answer:

  c.  (x^2+1)(x^2+a)-a = x^2(x^2+a+1)

Step-by-step explanation:

You can use FOIL or the distributive property to expand the product of binomials, Then collect terms and factor out the common factor.

  (x^2+1)(x^2+a)-a

  = x^2(x^2 +a) +1(x^2 +a) -a

  = x^4 +ax^2 +x^2 +a -a

  = x^4 +ax^2 +x^2

  = x^2(x^2 +a +1) . . . . . matches choice C

92% of x = 345 please explain. Thanks!
Alborosie
" of " means multiply......and turn ur percent to a decimal

0.92x = 345...divide both sides by 0.92
x = 345 / 0.92
x = 375.......so 92% of 375 is 345
