Answer: option D. 2x^2 + (3/2)x - 5
Explanation:
1) polynomials given:
f(x) = x/2 - 2 and g(x) = 2x^2 + x - 3
2) question: find (f + g) (x)
That means that f(x) + g(x), so you have to add up the two polynomials given.
3) x/2 - 2 + 2x^2 + x - 3
4) Combine like terms:
a) terms with x^2: you only have 2x^2, so it is not combined with other term.
b) terms with x: x/2 + x
that is a sum of fractions: x/2 + x = [x + 2x] / 2 = 3x / 2 = (3/2)x
c) constant terms: - 2 + (-3) = - 2 - 3 = - 5
5) Result: 2x^2 + (3/2)x - 5
That is the option d.
The product is 3.3333333333333 so less. hope this was helpfull
We have two equations
One to for the total number of units, to distinct them from 1 bedroom units or 2 bedroom units
x- one bedroom units
y- two bedroom units
x+y= 100
495x+600y= 55,275
We can try to plug in these values for y since it’s asks “how many two bedroom apartments are there” and see if it works out
495x+600(45)= 55,275
495x+27000=55275
-27000 -27000
495x= 28275
/495 /495
x=57.12
There can’t be 57.12 units so A is wrong
495x+600(55)= 55,275
495x+ 33000= 55275
-33000 -33000
495x =22275
/495 /495
x=45
This could work so B is the answer , you could go ahead and try C and B but most likely the answer is B
