Okay, so you what you would is solve one equation for Y=mx+b and then substitute this equation for Y so the answer would be Y=-3/2x + 20
And then you would do 2x-3(-3/2x+20)=-11 and you solve it for x
But to get y you would substitute what you got for x into ether equations.
Answer:
amplitude = 5
Step-by-step explanation:
The amplitude is the average of the maximum value subtract the minimum value
maximum value = 6 and minimum value = - 4, hence
amplitude = = = 5
Two consecutive integers would be 13 and 14
because 13 x 13 = 169 and 14 x 14 = 196 and the inequality fits inbetween perfectly.
You would make two mountains because you need to compare the two factor mountains
Answer: n=-5
Step-by-step explanation:
distribute: 0.6(10n+25)=10+5n 0.6(10n)= 6n 0.6(25)=15 so then you put the problem together again... 6n+15=10+5n then you cancel out the n variable... 10-15=-5 6n=-5+5n 6n-5n=1n 1n=-5 -5/1 n=-5
