This is the concept of quadratic equations, to find out whether the two expressions we need to expand each of them:
(x)=(25+10x)(300-36x)
(x)=25(300-36x)+10x(300-36x)
(x)=7500-900x+3000x-360x^2
(x)=7500+2100x-360x^2
Expanding equation 2?
(x)=(100+20x)(100-12x)
(x)=100(100-12x)+20x(100-12x)
(x)=10000-1200x+2000x-240x^2
(x)=10000+800x-240x^2
considering the lead coeffienct
7500+2100x-360x^2≠10000+800x-240x^2
Answer:
We could start with the simpler function f(x) = IxI and construct the other function using transformations.
First, an horizontal translation of A units to the right is written as:
g(x) = f(x - A)
And an vertical translation of A units up, is written as:
g(x) = f(x) + A.
Where A is positive and this works for any function f(x).
Then in this case, if we start with:
f(x) = IxI and:
g(x) = Ix - 2I -3
Then:
First we do an horizontal translation of 2 units to the right.
g(x) = f(x - 2) = Ix - 2I
Then we do a vertical translation of -3 units up (or a translation of 3 units down)
g(x) = f(x - 2) - 3 = Ix - 2I - 3
Those two transformations are the ones that relate the graphs of g(x) and f(x)

Answer:
765 grams
Step-by-step explanation:
Exchange:
2.33 kg = 2330 gr
Grams of grapes that are left after giving 800 grams to her brother:
2330 - 800 = 1530 gr
Grams of grapes each sister will get if Doreen shares the remaining equally:
1530 : 2 = 765 gr
