They want you to combine the variables. So
−12x4 + 7x3 + 6x4 − 2x3 =
<span>5x3 − 6x4
</span>So you combine the coefficients, not the variable number, for instance -12+6=-6, and then you simply put the variable in the same place it was. You don't do anything else with it except what I just showed you : )

Answer:
18 years
Step-by-step explanation:
20,010 = 8700*(1.05)^x
x = log_21/20 (23/10)
x = 17.07125
<span>Hello : let
A(-10,-3) B(7,14)
the slope is : (YB - YA)/(XB -XA)
(14+3)/17) = 1
an equation is : y=ax+b a is a slope</span>
y = x +b
the line F through point B(7,14) :
14 =7+b<span>
<span>b = 7
the equation is : y =X+7</span></span>
<span>the x- intercept of F when y=0 : x+7 =0 so : x = - 7 </span>
