Answer is 9
A(x)=f(b)-f(a)/b-a
where a=-10 b=10
f(x)= x^2+9x+18
f(a)=(-10)^2-90+18=28
f(b)=208
A(x)=208-28/10+10
A(x)=180/20=9
Answer:
Step-by-step explanation:
Well if you make them both equal to y I got...
Y=-3x+1
Y=5x-3
But I don't think you can find it without the y since they are different variables. Like I know -3x and 5x are the slopes and 1 and -3 are the y intercepts but I'm stuck after that. Sorry if that wasn't any help.
Hope I helped.
The Answer to your question ∑ (2k -10) from 3 to k=6 is -4
13+13+13+13=52, not 43 .
<span>43 is a prime number therefore the only two factors are 1 and itself, Technically, you can say that 21.5 multiplied by 2 would be 43.</span>
