Answer:
ok put into y=mx+b form
2y=60x+120
y=30x+60
so we know 60 is the y-intercept so he is not correct
if u want more:
-60x+2y-120=0 add 60x
2y-120=60x add 120
2y=60x+120 divide by 2
y=30x+60
Hope this helps plz hit the crown :D
Answer:
Step-by-step explanation:
total profit=income -cost
or
P(x)=R(x)-C(x)=-0.5x²+800x-100-(300 x+250)
or P(x)=-0.5x²+800x-100-300x-250
or P(x)=-0.5 x²+500 x-350
so (2)
Answer:
1. 8/$12=21/$x then cross multiply.
2. 1/$1.5, we're looking for cost so $1 is more reasonable
3. $31.5
Step-by-step explanation:
12x 21/ 8 = 31.5
first off let's recall that a square has all equal sides, so its area is just one side squared, namely A = s², or A = (s)(s).
we know the area is 16j² + 24j + 9, that simply means that two twin factors are in it, and it also means that the area polynomial is a perfect square trinomial.
