Answer:
1. c.
2. a.
3. b.
Step-by-step explanation:
Remember f(x) = y
1. f(x) = y = 2/5x+8
2. f(x)= y - 8 = x => y = 8 +x
3. f(x) = y = x - 8
Answer:
Step-by-step explanation:
we have
we know that
The formula to solve a quadratic equation of the form
is equal to
in this problem we have
so
substitute in the formula
therefore
StartFraction 19 minus StartRoot 365 EndRoot Over 2 EndFraction comma StartFraction 19 + StartRoot 365 EndRoot Over 2 EndFraction
Just put 4 as x in the equation and solve it. The new equation is:
sqrt(2*4)+1+3 = 0
Now we can solve it.
sqrt(2*4) becomes sqrt8:
sqrt8+1+3=0. -------> sqrt8+4=0
The sqrt of 8 is about 2.83.. so 2.83+4 is:
6.83
So we have 6.83 as the answer
but 6.83 does not equal 0 so x cannot equal 4
Answer:
A. x + y > 30 8x + 10y ≥ 450
Step-by-step explanation:
x+y bunnies and puppies has to be greater than 30 (in amount)
the amount of money need to be greater than or equal to 450 for both x bunnies and y puppies.
