I am pretty sure it is linear decrease,

Step-by-step explanation:
i first started with 18×8=144 then i did 144-119 and got 25.
Answer:
(2g^2h^3)^(2g^2h^3) OR 4gg^4hh^9
Step-by-step explanation:
I'm back so
80% of 12=9.6 grams=gold so
so she wants to add to the alloy to make the gold 92.5% gold so
I'm not sure how to do A or B but I think the answer to B is 2.4 grams
C. so the jewler has 2.4 grams of alloy
we must find out when 2.4=7.5%, what is 100%
so if 2.4=.075x then 24=0.75x then 32 grams=100 %
so 32-2.4=29.6 grams
29.6/32=0.925 or 92.5%
this is not the legit way to do it
Answer:
y = 4x + 9/4
Step-by-step explanation:
4x − y − 3 = 0
y = 4x − 3
The slope of the line is 4.
The slope of the tangent line is:
f(x) = x − x²
f'(x) = 1 − 2x
Setting the slope equal to 4:
4 = 1 − 2x
2x = -3
x = -3/2
The point on f(x) is:
f(-3/2) = -3/2 − (-3/2)²
f(-3/2) = -3/2 − 9/4
f(-3/2) = -15/4
Using point-slope form:
y − (-15/4) = 4 (x − (-3/2))
y + 15/4 = 4 (x + 3/2)
y + 15/4 = 4x + 6
y = 4x + 9/4
