its A
Answer:
-8
Step-by-step explanation:
-31 and +31 cancel each other out leaving you with -8
Answer:
D. 8
Step-by-step explanation:
y varies jointly as x and z
y = k(xz)
-------------------------
Find k, the constant of variation
y = 12 when x = -2 and z=3
12 = k(-2 * 3)
12 = k(-6)
k = -2
-------------------------
find y when x is 4 and z is -1
using k = -2
y = -2(4 * -1)
y = -2(-4)
y = 8
<h3>I’ll teach you how to solve 5x^3 - 3x^2 - 14x</h3>
--------------------------------------------------------
5x^3 - 3x^2 - 14x
Factor out the common term x:
x(5x^2 - 3x 14)
Factor 5x^2 - 3x 14:
Break the expression into groups:
(5x62+7x)+(-10x-14)
Factor out x from 5x^2+7x:
x(5x+7)
Factor out -2 from -10x-14:
-2(5x+7)
x(5x+7)-2(5x+7)
Factor out the common term 5x+7:
(5x+7)(x-2)
x(x+7)(x-2)
Your Answer Is x(x+7)(x-2)
